Mozilla Addons Blog: Introducing enterprise add-on policies

We are thrilled to announce that enterprise add-ons will launch on addons.mozilla.org (AMO) on December 1, 2026.

In response to input from enterprise organizations that distribute add-ons strictly via Firefox enterprise policies, we are establishing a dedicated enterprise release channel.

This tailored channel directly serves enterprise developers' requirements while freeing up resources to continue supporting non-enterprise developers.

Why enterprise add-ons need their own policies

Many organizations rely on Firefox add-ons to keep their people and data safe: security tools, data loss prevention, identity and access management, and internal productivity tools. These add-ons work very differently from the ones most people install from AMO:

Until now, these add-ons went through the same manual review queue as everyone else, under rules written for consumer add-ons. That slowed organizations relying on Firefox and took reviewer time away from the rest of the community without making a meaningful impact.

What is changing on December 1

The full policy text will be published on Extension Workshop. Until December 1, the current policies remain in effect.

How to take advantage of it

If you build add-ons for organizations: Read the enterprise add-on policies, and get ready to submit your enterprise versions through the enterprise channel from December 1.

In a nutshell, you must self-declare the enterprise status via the specific manifest key

"browser_specific_settings": {
   "gecko": {
      "admin_install_only": true
   }
}

If you build public add-ons: Nothing changes in how you submit or how your add-on is reviewed. The only thing you need to do is accept the updated agreement when prompted.

Quick Q&A: Who is this for?

Who are the enterprise add-on policies for?

Developers whose add-ons are built for organizations and deployed to managed Firefox installations through enterprise policies.

I'm an individual developer with a public add-on on AMO. Does this affect me?

Your submission process doesn't change, but you will need to accept the updated developer agreement.

My add-on is used by companies, but people also install it themselves from AMO. Is it an enterprise add-on?

Only versions you submit through the enterprise channel are enterprise versions, and those are available only through that channel. To keep your add-on listed on AMO, keep submitting it the usual way.

I only build an add-on for my own company's employees. Is this for me?

It can be. You can use the enterprise channel, or choose self-distribution, which is often the simplest route for add-ons meant for a smaller population.

I'm an IT administrator, not a developer. Do I need to do anything?

No. You keep deploying add-ons with Firefox enterprise policies as you do today.

Do I really need to accept the updated agreement?

Yes. Every developer on AMO, enterprise or not, needs to accept it, because the new policies are part of it.

When does this take effect?

December 1, 2026.

The Mozilla Blog: Skip the busywork with Smart Window

The days might be getting shorter, but your to-do list is only getting longer. Whether you're getting a head start on holiday shopping or planning your next career move, Smart Window's newest features will help you keep up.

Firefox's opt-in AI browsing experience can now use information from tabs you choose to help fill out forms. It can also watch web pages and notify you about specific changes you've asked it to track.

Let your open tabs fill in the blanks

Job applications ask for your work history; event registrations ask for a professional bio. If those details are already in your open tabs, Smart Window can now use pages you choose to suggest what to enter, saving you extra clicks and some Ctrl+C, Ctrl+V.

For example, Smart Window could use information from your online portfolio or professional profile to fill in your work history, or draw on those details to draft an answer to a question like "Tell me about a time when…" Firefox's regular autofill still handles saved information such as your name and address, which can be entered directly into forms without relying on AI models.

To get started, click into a form field. If the form has at least four text fields that Smart Window can help fill, you'll see "Fill from sources" appear in the dropdown, along with a recommended source page. Select "Fill from sources" to continue, or click the pencil icon to open "Edit sources" if you want to change or add tabs. Once you've chosen your sources, review the suggestions before filling out the form. You can edit the results before submitting; Smart Window won't submit the form for you.

When you choose to use this feature, information from your selected source pages is shared with Gemini 3.1 Flash Lite, the AI model used for detecting the fields and extracting relevant information from your selected tabs. Your model choice for Smart Window chat stays the same, and saved autofill values stay on your device. Learn more about how form filling works.

This feature currently supports text fields on web forms and does not save any generated form fill data. We're exploring support for more field types, including dropdown menus, as well as PDF forms and ways to save and manage generated information for future forms.

Give your refresh button a break

A watched pot never boils, and refreshing a web page won't make an update appear any sooner.

Smart Window can now watch a page for a specific update, whether that's an item going on sale or a new job listing that includes a job title or company name that you're following. Each task can follow up to five pages, so you can keep an eye on several stores or job boards at the same time.

Type "/watch" in the Smart Window chat to set up a task. Describe what you're looking for, add the pages to watch, and choose whether Firefox should check for updates on a daily or weekly basis. Those checks run only while the browser is open.

When there's a match, you'll see an update through the Tasks button in the toolbar. With desktop notifications enabled, Firefox can also notify you directly; click the notification to open the watched pages. You can have up to 15 active tasks at a time, and you can edit, pause or delete tasks. Smart Window will automatically pause tasks after 60 days without a matching change. If 90 days pass without a change, it will stop checking altogether.

Page monitoring uses the Qwen AI model to identify changes that match what you're looking for. Your model choice for Smart Window chat stays the same. Learn more about creating and managing tasks.

Try the latest additions

These two new features are available in the Smart Window beta on desktop, in English in the U.S. and Canada, and will roll out to additional markets in the coming months.

Try Smart Window and share your experience on Mozilla Connect. We'd love to hear how you're using Smart Window to get things done and what you'd like it to help with next.

The Mozilla Blog: Five Firefox updates you might have missed, and a look ahead

Some of our latest Firefox updates have had big moments of their own, from the launch of our new design and built-in ad blocking on iOS to Firefox Enterprise and our partnership with NVIDIA GeForce NOW. You might've even spotted a few familiar internet OGs in our latest campaign. Other improvements might've flown under the radar until you open a PDF or move your tabs around.

We wanted to take a moment to highlight some of the features and improvements we've been working on, from recent additions you might have missed to a look at what's coming next.

What's new in Firefox

  1. Open PDFs faster. Firefox's built-in PDF viewer now starts up to 45% faster on desktop, so there's less waiting when you open a document in your browser.
  2. Put your Android tabs where you want them. Prefer your tabs at the bottom of the screen? You now have the option to move Firefox's tab bar there. Go to Settings > Customize to choose.
  3. Find your spot in a video faster. We've made it quicker to jump to a different point in a video on desktop, whether you're skipping ahead in a tutorial or going back to catch something you missed.
  4. Keep your favorite wallpapers handy. Firefox now saves a collection of your custom wallpapers under "Your images" on New Tab on desktop, so you can switch between favorites without uploading them again.
  5. Save time filling out forms and keeping up with page changes. Smart Window can now help fill out online forms using information from your chosen tabs, so you don't have to copy details back and forth. You can also ask it to watch a page and notify you when something changes, like a price drop or a new job listing, saving you from manually checking for updates. Both capabilities are available in English in the U.S. and Canada as part of the Smart Window beta. Learn more about the new features here.

What's next on the Firefox roadmap

When we launched our public roadmap in June, we shared plans to make everyday browsing more useful, flexible and private. We've now updated it with more of what's ahead. We're developing these features in the open, in close partnership with our contributors, and will share more about release timing as each feature gets ready for more people to try.

Here's a look at what's in the works:

Keep shaping Firefox with us

Try the latest updates and explore the Firefox roadmap for more of what we're working on. If there's something you're looking forward to, or something you'd like us to improve, tell us on Mozilla Connect. Your feedback helps shape what comes next.

Mozilla Privacy Blog: A Reason for Optimism on US Competition Policy

Mozilla has long called for US antitrust reform in digital markets. After several false starts, real change has yet to materialize. In the meantime, dominant tech players have further entrenched their hold, limiting choice and degrading people's experiences. Integration of new AI services into existing ecosystems is enabling those same companies to perpetuate and accelerate that power.

But, there's reason for optimism. Momentum is again building toward antitrust reform, and this time feels different. With support from start ups, middle tech challengers, civil society, and think tanks across the political spectrum - and most importantly, legislative champions in Congress - it's clear that the time is coming.

This is a debate about how the largest tech companies control the products and innovations in the market, and access to the services the people use every day. At the center are questions about user choice, interoperability, privacy, security and whether independent innovators have an opportunity to compete on merit.

These topics were the focus of a recent Senate briefing hosted by Bull Moose Project and Public Knowledge, diving in on three competition bills before the Senate Judiciary Committee: The American Innovation and Choice Online Act (AICOA), the Open App Markets Act (OAMA), and the America Act. The discussion brought together policy experts and industry voices, including Mozilla, to explore how competition policy can improve people's experiences online and the ability of challenger companies to succeed.

The conversation covered a range of issues, from whether existing antitrust laws are equipped to address today's digital markets, to misguided claims about what might happen if we pass antitrust reform, and the ways that dominant platforms dictate how people discover and use competing products. For Mozilla, an important part of the conversation is what meaningful user choice looks like in practice. People should be able to choose alternatives, and those choices should be respected. But structural barriers can make it harder for independent players to compete on merit, and for people to access options, including independent products that innovate in areas like privacy and security. Competition creates stronger incentives for companies to build better, and to give people the protections and products that they deserve.

Antitrust reform is not about punishing companies for being successful. It's about ensuring that independent players can provide the best possible versions of their products, and that people can truly benefit from those innovations. That's why Mozilla, alongside many others, has long championed AICOA and worked to tackle longstanding anticompetitive practices. We're excited to see newly energized support across the public and private sector, and for the next steps in advancing legislation.

Mozilla Addons Blog: Developer Spotlight: Profile Manager Pro

If your online activities involve logging in and out of a lot of different accounts - often on the same website - Profile Manager Pro can be a time-saving game changer. The extension provides a one-click login process for multiple online accounts, so you can effortlessly jump between profiles. From social media management to web development, QA testing and more, Profile Manager Pro removes the painstaking friction of constant account switching.

Simple UI makes it easy to jump between multiple accounts across various sites.

"One of the most interesting aspects of developing Profile Manager Pro is realizing how many different workflows can benefit from efficient account switching," explains its creator, Islam Elsayed. Consider developers who need to save sessions for different roles, such as admins, moderators or regular users, to test functionality; freelancers working across multiple client dashboards; or support professionals investigating account-specific behavior. The potential uses for Profile Manager Pro are practically limitless.

Elsayed makes clear that Profile Manager Pro isn't intended to replace Firefox's full browser profiles; rather, the aim is to make it easier to save, organize, and restore individual website sessions within a browser environment. "I think that distinction is important because it illustrates how browser extensions can complement existing browser capabilities by addressing very specific everyday frustrations."

While the extension provides a fairly straightforward function, its design and development were anything but simple. Elsayed says his biggest development hurdle was creating a reliable account-switching experience across websites that handle authentication and session management differently. Modern websites often use tangled combinations of cookies, browser storage, authentication tokens and other complex security mechanisms. A technical solution that works perfectly on one website may not function at all on another. "These challenges taught me an important lesson: The best productivity tools often hide considerable technical complexity behind a simple user experience."

Another challenge is balancing functionality with user privacy and security. Session-management extensions interact with sensitive browser data, so Elsayed goes to great lengths to ensure user protection - starting with a local-first approach to development. Saved session information stays within the user's browser environment by default. Users don't need to create a Profile Manager Pro account or send their browsing sessions to a third-party server. The extension also offers optional encrypted Google Drive sync, providing even more control over stored data.

"Responsible session management is essential," says Elsayed. "This is why I believe privacy should be considered throughout the design process rather than an afterthought. Ultimately, my goal is to give users convenience without requiring them to surrender unnecessary control over their data."

As for future development plans, Elsayed frames Profile Manager Pro as an "evolving project." He intends to focus on optimizing the profile management system and improving backup and sync experiences.

"My long-term vision for Profile Manager Pro is to become an increasingly powerful yet lightweight tool for managing online identities and workflows," says Elsayed. "I believe thoughtful improvements based on real user needs are more valuable than adding features simply for the sake of adding them. For me, the most rewarding part of development is solving those complex problems so users don't have to think about them."

The Rust Programming Language Blog: How to fund Rust contributors

TLDR:

There is always so much to do in the Rust Project! New features to implement, bugs to fix, performance optimizations to make, issues to triage… It takes a lot of work to keep our high bar of quality while also shipping new features and improvements. And the workload keeps increasing with the continuous growth of Rust adoption.

As is unfortunately common in open source projects, a large fraction of that work is currently done by volunteers. That causes various issues, such as people burning out or complex features taking many years to ship.

Unsurprisingly, one of the best ways to help improve that is to get more people who work on Rust funded! This year, several funding initiatives started ramping up, and we already experience many positive effects. They helped us improve the maintenance status of critical Rust projects and make significant progress on several long-awaited features, such as allocators, the never type, the next trait solver or the Polonius borrow checker. However, only a fraction of people working on Rust are currently funded for their work.

We know that there are Rust users, both individuals and companies, who would like to help improve Rust by funding it, but it might not always be obvious how exactly to do that. This post thus provides suggestions on how you can support the development of Rust in three ways.

If you're unsure which option fits, or would like to discuss funding on behalf of your company, please contact the Funding team.

Fund general maintenance

Maintenance is a continuous process required to keep Rust (or any software project for that matter) working. It consists of two main activities. The first is general housekeeping, such as ensuring that Continuous Integration works, dependencies are kept up-to-date and issues, bugs and security incidents are promptly triaged and resolved. The second is performing refactorings and code reviews, which ensures that the codebase will be able to evolve and continuously ship new features, without accruing extensive technical debt.

Having quality maintenance is crucial for the long-term health of Rust, yet it is typically very difficult to find funding for it; funders often want to sponsor specific new features, rather than just "keeping the lights on". However, without sufficient maintenance, it becomes much more difficult, and much slower, to ship new features. Improving the maintenance of Rust thus also helps us ship features and improvements faster, though the effects are sometimes only observable over longer periods of time.

Funding maintenance is a great choice if you want to let us decide how best to improve Rust. The Rust Funding team continuously looks for Rust teams and projects that require help with their maintenance efforts, and allocates available funds to Rust maintainers who could help improve the situation.

To fund Rust maintainers, consider donating to the Rust Foundation Maintainers Fund or sponsoring the RustNL Maintainers Team.

Fund specific features and improvements

There are always many Rust improvements and new features that are in progress. We track some of those initiatives through Rust Project Goals. Each Goal describes a specific improvement to Rust: what it is, who is going to develop and drive it forward and which Rust teams are willing to help reviewing and maintaining it.

Some of those Goals are looking for funding. Either to help their owner dedicate time and focus to push the given feature forward, or to fund maintainers who will perform refactorings necessary to unblock that feature and review its implementation. Often funding is required for both. When a Goal is properly funded, the probability that it will achieve its milestones is much higher, which then translates in the given improvement being shipped sooner to Rust users.

Funding Project Goals is a great choice if you want to help push forward specific Rust features or Rust toolchain improvements that will benefit you or your company.

To fund contributors working on Project Goals, consider taking a look at Goals that need funding and reaching out to their funding contact. If in doubt how to proceed, reach out to the Rust Funding team.

Fund individual contributors

There are hundreds of people in the Rust Project who continuously work on improving Rust. Some of them have personal fundraising profiles (e.g. on GitHub Sponsors), which allows you to support them directly.

There might be various reasons for supporting a specific person. Maybe they are maintaining a crate that you love to use, maybe you like reading their blog posts, or maybe you are simply a fan of the work that they do. Whatever the reason, we are sure that they would appreciate your support!

Funding individual contributors is a great choice if you want to directly support Rust contributors whose work you appreciate.

To fund individual Rust contributors, check out their GitHub profile or personal website to see what options there are for supporting them. You can also examine our list of Rust Project members who can be supported through GitHub Sponsors[1].

Conclusion

We hope that this post is useful to anyone who would potentially like to invest funds into making Rust better. You can also find a shortened version of the "how to fund Rust guide" at the Funding page of the Rust website, or check out a RustConf 2026 talk by Niko Matsakis about how Project Goals and their funding works.

If you are a company looking to fund the development of Rust, consider joining the Rust Commercial Network. Joining the network is free, and Rust Foundation membership is not required. It can help you find opportunities for funding improvements in specific areas related to Rust usage (e.g. user interfaces, language interop, supply chain security, etc.) and collaborate on funding Rust development with other companies.

There are of course other ways of helping Rust other than donating funds. For example, you can check out Project Goals that are looking for contributors or more generally check our contributor onboarding guide. Companies can also help by giving employees paid time to contribute upstream, or by hiring Rust contributors to do that work. One possible model is the Engineer in Residence role, that was recently established in the Rust Foundation.

  1. Note that this list is not exhaustive; there are some Project members who accept donations through GitHub Sponsors (or another fundraising platform), but did not opt into being listed on this page. ↩

The Mozilla Blog: Firefox reunites meme royalty to remind you what the internet used to feel like

A group of familiar faces from the early web just got back together to ask an important question: What happened to the internet?

Sure, there was a time when it was a little less polished, and a lot less speedy, but it was yours. Overly Attached Girlfriend may have wanted to know everything about you, but your browser didn't need to. Dancing Matt boogied all over the world, without any corporations tracking him or selling his personal data. And while Annoying Orange is incredibly annoying, he's not as annoying as forced AI features.

These beloved early internet personalities remind us of a time when surfing the web felt open, organic, and most importantly, personal. And good news: With Firefox, it still can.

That's why we're teaming up with these icons to remind people what our browser offers, and show those who wandered off why now is the time to come back.

The team behind the comeback

For Mozilla Chief Marketing Officer John Solomon, the aim of the campaign started with winning back people who originally loved and used Firefox.

"I kept going back to Firefox's heyday, when the internet was really fun, weird, and interesting. The challenge was: how do you lean on nostalgia and heritage, but not be stuck in the past?"

The campaign was created by We Believers, one of the world's most awarded independent agencies, with production handled by nobodys and direction by the Sunny Sixteen collective.

"We wanted to create an idea that truly belongs to Firefox - a challenger browser that helped shape the internet's golden years and stayed independent as Big Tech took over. The goal? Remind former users that what they loved about Firefox matters more than ever now," said Gustavo Lauria, Founder and CCO at We Believers.

Solomon said the finished campaign achieves the goal of embracing Firefox's history without living in it: "Our partners really cracked it. We wanted to remind people of what made the internet so wonderful in the first place. These are people who helped make it strange, creative, surprising, and fun. None of them were trying to go viral. They were normal, everyday people who were using the internet. That's the way the internet should be and why we feel it's a great moment for Firefox. Always independent and unlike big tech, not trying to extract more from everyday people."

The internet you remember is still out there

Whether you used Firefox back in the day, or are simply looking for a better browsing experience, we're still here, staying true to the values we were built on. We believe the internet should be open, accessible, and shaped by the people who use it, not just the platforms that profit from their attention and data.

This means a web where you can explore without feeling tracked or used for profit, where you decide for yourself how new technology fits into your life, and you can trust that your browser protects you by default. Firefox has built-in privacy protections to help limit tracking, lets you decide if AI features appear and customize how they behave, and uses open source code that anyone can see. To learn more about what sets Firefox apart, check out five reasons to choose the browser that puts you first.

We know a better internet isn't built by finding new ways to capture your attention or information. It's about giving you more freedom to make the web your own.

The web is yours to explore

The internet has changed a lot since Numa Numa Guy first danced his way into our collective memory. But the things that made it magical - creativity, curiosity, community, and the freedom to explore - are still worth protecting.

Firefox has championed those values since the beginning, and we're not giving up on them now. That's why we're celebrating the people who helped make the early web what it was, while reminding everyone that a more open, human internet is still an option.

The early days of the internet may be behind us, but the spirit doesn't have to be. Experience it for yourself. Now more than ever: come back to Firefox.

What's new or coming up in Firefox desktop

Felt privacy and protection

In upcoming versions of Firefox, there will be a number of updates focused making the privacy protection features of Firefox felt by the user, in addition to communicating those features in an easy to understand way. Translation has been ongoing and some of these will be released from Firefox 159.

Private Window redesign

A redesigned Private Window experience when opening a new Private Window will be rolled out in an experiment to users starting in Firefox 159, but can be viewed by opening about:config and setting the browser.privateWindowRedesign.enabled flag to true, then opening a new Private Window.

Fire button in Classic Mode

A button that allows users to start fresh in a browsing session, they can clear browsing data in a single click. Strings for this will mostly involve updated wording for existing strings around what data to clear. This is one of many features mentioned in the Firefox roadmap.

Privacy Panel

The privacy panel that shows your protection status for a website (accessible by clicking the shield icon in your address bar) will be getting a complete redesign to more prominently display the number of trackers blocked, important security warnings, and critical site issues. This is still in progress but expect to see strings soon.

Mini Window

An early version of this feature is coming up in Firefox 160 and strings are landing now. The Mini Window gives you the ability to detach a tab or custom section into an always-on-top, scaled-down frame. It expands on the familiar Picture-in-Picture functionality for general web content, making it effortless to keep documentation, messaging apps, or references visible as you work. You can find additional details and a demo of Mini Window on Mozilla Connect.

What's new or coming up in mobile

With our recent switch to releases in 2-week cadence, mobile will see a slew of small but mighty features pop-up in short succession. Some of the recently launched or soon-to-be revealed features include:

Firefox for Android

Firefox for iOS

What's new or coming up in web projects

Firefox Enterprise is here! It launched on October 13 alongside Firefox 158: Firefox with enterprise controls and a management console that organizations run on their own infrastructure. Read the announcement and explore the website.

The launch starts in France, Germany, Austria and Switzerland, so the website is live in English, French and German. Our translation agency handled these pages, so you won't find them in Pontoon. Thank you to everyone who has helped with firefox.com so far. If you're curious about how localization works for firefox.com and Firefox Enterprise, or have thoughts on it, you're always welcome to get in touch.

Strings for the main firefox.com website continue to land in the firefox.com project in Pontoon, for the locales that have it enabled.

What's new or coming up in SUMO

Semantic search is now live! It was officially launched with Kitsune 1.8.0 on October 6, 2026. This initial rollout is limited to Knowledge Base articles, with broader search improvements still to come. A big thank-you to everyone who participated in the testing phase and helped us improve the experience!

Dark mode is coming to SUMO! You can get an early look by watching the demo in the previous Monthly Community Call or you can also try it yourself on our staging site.

What's new or coming up in Pontoon

Monthly health reports. Following the Community Health Score introduced in the August report, teams can now opt into a monthly health report, delivered as both an email and an in-app notification, with a new toggle in contributor settings. The feature was developed by our intern Jamie (functionzz).

Editor and Machinery. The editor can autofill from composed Machinery matches, the 100% match indicator moved into the editor menu, and leaving an autofilled 100% TM match no longer triggers an unsaved-changes warning.

New contributors. We're happy to welcome another group of contributors who made their first patches to Pontoon in the past few months: baha-bouali (6 patches), scottcampbelldata (4), tahakotil (2), nyomanjyotisa (2), kwy404 (2), annki, Goudarz, Hanabi9248, HarshRajSinghania, and MaxFreedomPollard. Their work spans terminology, search and dropdown behavior, the API, plural handling, theming, insights, right-to-left support, and documentation - thank you all!

The Mozilla Blog: Still here, still yours: 5 reasons to choose Firefox

The internet used to feel like a community, not a commodity. Browsers were tools for exploration, and you could wander the web without feeling tracked everywhere.

Today, as the web becomes increasingly surveilled and commercialized, Firefox preserves the magic, freedom, and fun of the early internet. Still open source, still independent, still privacy-focused. No billionaire owner, no hidden agenda.

So, whether you're new here, back after a break, or just curious, here are five reasons to choose the browser that puts you first.

Backed by a non-profit, not billionaires

Firefox is backed by the Mozilla Foundation, a non-profit committed to an open internet. Unlike other big tech companies, we're built with privacy as the default. Our open source code is visible, reviewable, and continuously stress-tested by a global community, truly putting power in the hands of the people it's built for.

Private and fast by design

While other browsers allow third-party trackers to profile you, Firefox's Enhanced Tracking Protection (ETP) helps stop cross-site tracking before it starts, letting your browser work faster. Plus, when you sync information like history and bookmarks across devices, it's encrypted locally, meaning only you can access it.

Learn about some of our other privacy-focused features like password manager, built-in VPN, and Relay in our guide to strengthening your online security for free with Firefox.

AI on your terms

We believe the only person who should decide how you interact with AI features in your browser is you. Firefox offers a clear, easily accessible AI controls section where you can turn off AI features entirely - or decide which ones stay on depending on your workflow and preferences.

For those wanting a little more help getting things done, Smart Window is Firefox's most integrated AI experience. With your permission, its built-in, AI-powered assistant can work directly with your open tabs and browsing history to connect the dots. This means it can compare information, summarize pages, and help plan projects without requiring you to provide context from your past and current browsing activity every time you start a new prompt.

Newer feature additions to Smart Window include the ability to group related tabs together and visual history previews that help you find a page you visited earlier when you can't remember the exact URL or phrase searched. Also, our partnership with Exa enables Smart Window to find current web information to include in responses while also displaying the sources behind these answers, so you can verify what you're seeing without interrupting your workflow.

Smart Window remains in beta as we continue to learn and improve from our community's feedback. Try it yourself here.

Not just Chrome in disguise

Firefox is not built on Chromium, the open source browser project that supports Google Chrome and many other browsers. As a matter of fact, we are one of the last major browsers that isn't.

Instead, Firefox runs on Mozilla's independent Gecko browser engine, which was developed specifically to uphold our strong privacy standards and give people more control over their data and browsing experience.

This independence also impacts how Firefox handles browser add-ons, particularly ad blockers. Unlike Chromium-based browsers that now limit how powerful ad-blocking tools can be, Firefox still allows ad blockers like uBlock Origin to work at full strength. This means people who use Firefox can enjoy stronger, more reliable ad and tracker blocking without compromise, something increasingly difficult on Chromium-based browsers due to imposed limitations.

Plus, we have a really cute Firefox

Firefox is constantly building features and solutions to help you navigate the web on your own terms, and we wanted to make this support visible. Enter Kit, Firefox's companion to the internet.

Kit isn't an AI assistant or chatbot, just a friendly face that you might see during moments that are meant to feel friendly and supportive, like when you're just getting set up, exploring a new feature, or celebrating a win such as successfully adjusting a setting.

Rooted in values, built for you

While the internet is ever-changing, Firefox remains rooted in the values that defined its beginning. Our browser was created on the principles of privacy, independence, and choice,and we continue to uphold them as we innovate and evolve.

In a web landscape dominated by profit, surveillance, and sameness, our browser preserves the open and human spirit of the early internet. New, returning, or loyal for years, there's always a place for you here.

Download Firefox and make the web yours again.
