New release of Firefox DevTools MCP. Available on npm at https://www.npmjs.com/package/@mozilla/firefox-devtools-mcp

Fixed

• set_firefox_prefs and get_firefox_prefs work again. They now use WebDriver BiDi to run in the privileged context
• list_pages no longer fails when the URL or title of a tab cannot be read. That tab is listed with (unknown) values instead

Changed

• take_snapshot and the UID-based input tools now use WebDriver BiDi instead of WebDriver Classic
• The snapshot script now runs in a sandbox, so page scripts cannot interfere with it and it does not add globals to the page
• The Cursor plugin manifest is replaced by the root plugin.json and mcp.json files from the Agent Plugins 1.0 standard, which cursor.directory reads

Full changelog: Release v0.10.5 · mozilla/firefox-devtools-mcp · GitHub
Repository and issues: GitHub - mozilla/firefox-devtools-mcp: Model Context Protocol server for Firefox DevTools - enables AI assistants to inspect and control Firefox browser through WebDriver BiDi · GitHub

Encryption is woven into everyday digital life. It protects our messages and passwords, but also banking and payments, health data, government services and the digital infrastructure societies rely on every day. Yet across jurisdictions, governments are increasingly considering laws that expand lawful access to data for law enforcement and national security purposes. In practice, this can mean requiring companies to create new ways to access encrypted data, introduce technical capabilities that bypass existing protections, or make otherwise secure systems insecure. These measures can weaken the very security encryption is designed to provide, with consequences for cybersecurity, privacy, fundamental rights and the wider economy. Canada's Bill C-22 is the latest example of this trend, raising serious concerns about the security and privacy consequences of expanding government access to data.

For Mozilla, protecting that security is fundamental to both the products we build and the principles we advocate for. One of the foundational principles that guide Mozilla's mission and work holds that individuals' security and privacy on the internet are fundamental and must not be treated as optional. Protecting people's privacy and security is not an aspiration for us, but shapes the products we build every day: Firefox blocks trackers, protects you from profiling via cookies and fingerprinting, comes with malware protection and a built-in VPN, offers HTTPs-only mode and protects your passwords and credit card information by encrypting them.

Some of these protections are being threatened by Canada's Lawful Access Act, also known as bill C-22. Part two of the bill, the "Supporting Authorized Access to Information Act" (SAAIA) would introduce sweeping new powers to require electronic service providers to build and maintain capabilities that facilitate government access to information. If passed in its current form, companies could be asked to introduce vulnerabilities, build backdoors, bypass, weaken or otherwise defeat encryption, access data before encryption or decrypt encrypted data to provide access to law enforcement. Service providers could also be compelled to retain and access data they have purposefully chosen not to collect.

Let us be clear: there is no safe way to create exceptional access to encrypted data that only the intended actor can use. An access mechanism created for law enforcement can also be discovered, exploited or abused by potentially bad actors.

Such vulnerabilities and backdoors do not only undermine people's fundamental rights to privacy and data protection, but also the trust and security premises societies everywhere depend on. The same encryption that protects a private conversation also protects financial transactions, sensitive health information, business systems and critical digital services.

Expanding capabilities of AI systems are only exacerbating these risks - governments should encourage the disclosure and patching of vulnerabilities, not compel companies to introduce insecurities deliberately. Only trustworthy and transparently governed digital infrastructures can be the basis for digitally sovereign societies.

We are also concerned by C-22's scope, which does not stop at Canadian services or users. C-22 expansive surveillance capabilities and data retention obligations would undermine people's privacy and security everywhere, and the bill's confidentiality requirements would make it impossible for services to inform their users about security breaches or backdoors introduced.

Guided by our Surveillance Principles for a Secure, Trusted Internet, we call on Canadian policymakers not to rush the legislative process to take experts' feedback into account in amending C-22 to protect everyone's security and privacy. Canada's interests are best served by regulation that protects encryption, strengthens cybersecurity and emphasizes transparency, checks and balances.

Firefox is teaming up with AEG and taking to the main stage at Berlin's biggest and best indoor arenas. Starting this October, as the indoor music scene heats up and the basketball and ice hockey seasons are in full swing, fans flocking to the Uber Arena, Uber Eats Music Hall, and Uber Platz will see Firefox highly visible around the venue. They may even bump into our very own mascot, Kit, who will be on hand to help them skip the main queues courtesy of Firefox.

We know that the experiences people care about often begin online. The internet is the gateway to how they discover, plan, and navigate their way to concerts, sports events, and nights out before they happen in real life.

Firefox's presence will help make every step of that journey simple and smoother, starting at the door.

People with Firefox downloaded on their phone will have access to a dedicated Firefox Fast Lane that allows them to skip the main line at the Uber Arena. To ensure the smoothest possible entry, a QR code for downloading Firefox will also be available at the Fast Lane.

"People who use Firefox tend to choose things deliberately, their browser, their music, their nights out. This partnership is for them. A first for Firefox. Most browsers want more of your time online. We want you at the show, faster. Berlin is where we are starting, right across the river from our office. See you there," said John Solomon, Mozilla-Firefox Chief Marketing Officer.

We are excited to bring what we stand for to Berlin's premier entertainment venue - choice, control, and a better experience to the moments that people want to enjoy and truly care about.
