Highlights

• Here are some big-ticket volunteer contributions this week:
  • Thank you to volunteer contributor Cornelius, who made console evaluation able to re-declare let and const variables in our DevTools!
  • Thank you to F3tch, who landed several patches to allow setting of camera and microphone permissions, reject zero-sized screenshots, and add a vendor-specific WebDriver BiDi command for listing installed extensions, as well as update cookie test expirations.
  • Thank you to SMRehan, who landed a (disabled by default) mode that lets Picture-in-Picture open when the browsing window is occluded (as opposed to when changing tabs).
    • This can be tested by setting media.videocontrols.picture-in-picture.enable-when-occluded.enabled to true
  • In Nightly 160, we have enabled the playback speed feature for Picture-in-Picture by default:
  • Thank you to volunteer contributor Simon Rosen for the bulk of the initial work on this!
• The custom wallpaper library for newtab is now available, starting in Firefox 158, so you can now store multiple custom wallpapers:

WebDriver

• Beatriz Rizental improved the Marionette harness to accept multiple -tag arguments similar to other in-tree harnesses.
• Khalid AlHaddad improved the PollPromise to throw an error by default and not only log a warning when it times out.
• Alexandra Borovova added support for the imageSize argument to the browsingContext.captureScreenshot command, which allows clients to specify the maximum size of the resulting screenshot image.
• Alexandra Borovova added support for the destinationFolder argument to the browsingContext.startScreencast command, which allows clients to choose the folder where the recorded video file is saved.
• Alexandra Borovova implemented the support for the prefers-color-scheme parameter in the emulation.setMediaFeaturesOverride command, which lets clients emulate dark or light mode on a website.
• Henrik Skupin improved the handling of recommended preferences for automation to use the default branch, preventing them from leaking into subsequent Firefox sessions.
• Henrik Skupin fixed a bug where accepted server sockets still had Nagle's algorithm enabled, causing up to 40ms delays for back-to-back writes on Linux.
• Henrik Skupin improved geckodriver's shutdown handling by waiting for Firefox's hang monitor to terminate hung processes before force-killing them.
• Henrik Skupin added a temporary workaround to prevent Glean from causing shutdown hangs for short-lived Firefox processes.
• Holger Benl added machine-readable CDDL for all Firefox WebDriver BiDi vendor extensions ("moz:" commands, events, parameters, capabilities…).
• Privileged context support was added to browsingContext.locateNodes and input.performActions by Holger Benl, and to browsingContext.captureScreenshot by Julian Descottes.
• Julian Descottes fixed the network.getData command to handle 304 - Not Modified responses with no timeouts.

Fluent

• Shout out to flod who's started to chip away again at migrating .properties files to Fluent!
  • For the first time since we started tracking, there are fewer than 4000 .properties strings in the Firefox source code!

Migration Improvements

• spohl is working on a stack of patches that'll update the migration workflow for macOS 27 to reduce the number of data access permission warnings that users see

New Tab Page

• We're testing a few different layout variations in the wild - one of them is a few different takes on "spaces":

• The MCAB search input is currently being deployed to a small population in the wild to see how it works / is received

• A train-hop is scheduled to be deployed this week which should make widgets available for all users (though for most users, these will be disabled by default - they'll be available to enable in the customize panel).

• Reem Hamoui removed the Enzyme/Karma test infrastructure from the New Tab Page, which is a CI/dev tooling change with no direct runtime user impact but should reduce test maintenance and flakiness for future user-facing fixes.
• Jack Brown switched New Tab message visibility checks to an IntersectionObserver so messages below the fold are no longer marked as activeNotifications, preventing offscreen messages from being targeted and avoiding unnecessary JS evaluation when not visible.
• Jack Brown cleared activeNotification targeting when navigating away from about:newtab so message targeting no longer persists after leaving the page, preventing carry‑over interactions and incorrect metrics attribution.
• akulyk [a11y] fixed dialog focus containment on the New Tab Page by enforcing a focus trap and proper Tab/Shift-Tab handling, restoring expected keyboard and screenreader workflows for modal dialogs.
• Scott fixed pocket.click and topsite.click to trigger context menus correctly, restoring right-click/long-press context menus on Pocket tiles and Top Sites so users can access actions like open-in-new-window and remove.
• Maxx Crawford updated per-widget Jest fixtures for Stocks, Privacy and Picture of the Day to omit the widgets.enabled flag in test setups Per-widget Jest fixtures for Stocks, Privacy and Picture of the Day omit widgets.enabled, which aligns test fixtures with runtime enablement behavior and reduces CI flakes and regression risk for those widgets; there is no runtime UI change for end users but widget rendering tests should be more reliable.
• Maxx Crawford removed the Sports widget from the New Tab Page and widget picker, which directly removes sports headline/cards from users' NTP experience (users who had Sports selected will no longer see it) and slightly reduces client-side DOM/paint work and widget surface area for future NTP changes. It also removed about 1MB of image / video assets from the omni.ja / newtab XPI.
• Maxx Crawford added region/locales dynamic control for the Weather widget, allowing users to change the Weather card's region/locale on New Tab so forecasts and localized labels update immediately.
• Herraj Luhano updated the POTD API contract to return the previous day's POTD, enabling the New Tab image module to fetch and display yesterday's Picture of the Day to avoid empty or stale image slots.
• Nina Pypchenko [:nina-py] re-ordered New Tab settings in about:preferences, improving discoverability by placing New Tab controls in a more consistent, prominent location for users managing Start Page options.
• Dre standardized context menu button UI across all widgets, unifying markup, CSS variables and ARIA to make context-menu hit areas and keyboard focus consistent across widget surfaces.
• Dre standardized header typography across all widgets, aligning font sizes, line-heights and tokens so widget headers render consistently on New Tab pages.
• Maxx Crawford updated WallpaperFeatureHighlight to allow for alternate strings to be injected so the New Tab wallpaper feature highlight UI can show injected copy variants (for localization or experiments), which directly changes the text users see in the wallpaper picker/highlight flow and should be monitored for clarification/regression in impressions and CTA click rates.
• David Durfee landed a meta change to enable score-based selection for sponsored tiles in the New Tab experiment, which replaces the previous selection heuristic with a ranking/scoring pipeline so experiment cohorts may see different sponsored tiles on New Tab (affects which ads/content are shown, sponsored impressions/CTR, and A/B metrics for desktop and mobile New Tab surfaces).
• Nina Pypchenko renamed the Stocks widget to "Finance" on the New Tab Page, updating the activity-stream UI/i18n label users see in the widget header.
• Brendan Birdsong adjusted the newtab score-based selection to sum day counts from remote-settings config, which can change which cards/tiles are selected and their ordering for users depending on remote config values.
• Scott Downe removed the discoverystream.optIn-region-weather-config pref from newtab, a config cleanup that does not change runtime New Tab UI or user-visible weather opt-in behavior.
• Irene Ni normalized the layout_name value in New Tab DSCard impression telemetry, ensuring consistent impression records for analytics and A/B experiments without altering the UI seen by users.
• Scott Downe removed the telemetry.structuredIngestion.endpoint pref from newtab, removing a pref-based override for structured-ingestion endpoints (affects developer/testing overrides, not regular user behavior).
• Irene Ni removed unused ImpressionStats dispatches from New Tab DSCard clicks, eliminating redundant telemetry dispatches on DSCard click paths with no UI change.
• Irene Ni normalized Top Sites telemetry keys to their Glean extra names, stabilizing telemetry naming for Top Sites without changing user-visible behavior.
• Dre fixed a slight flash when reusing a previously uploaded wallpaper in the New Tab Page, removing a visible flicker for users who set custom uploaded wallpapers.
• Maxx Crawford added a debug pref/setting to revert region controls, enabling targeted rollbacks/enabled testing for affected-region UI behaviors when the pref is toggled.
• Jared Wein fixed TypeScript errors in newtab/lib blocking inclusion in newtab's tsconfig.json, resolving a build/tooling blocker (developer-only change; no direct user impact).
• Irene Ni made the Spaces arrow-buttons variant background panel occupy the full page height on the New Tab Page, removing a visual gap and ensuring arrow controls stay aligned with page scroll.
• Alexandre Hanot fixed Ads client initialization on Firefox 157 and older so the Ads client now initializes instead of throwing errors on legacy builds, restoring ad content on affected users' New Tab Pages.
• Dre prevented the Clocks widget menu button from overlapping clocks on hover by adjusting z-index and hover layout, restoring visibility and correct hit targets on the New Tab Page.
• Irene Ni enabled a widget in the first content position of New Tab sections, updating New Tab rendering logic so a prioritized widget slot is populated in the first content position and becomes visible by default to users.
• Jared Wein enabled type checking for newtab/lib with exception for failing files, adding incremental static-analysis/CI checks to catch regressions in newtab code without changing UI behavior today.
• Maxx Crawford set default enabled value to false for all existing widgets, changing widget metadata/prefs so existing widgets are opt-in and will no longer render for users unless explicitly enabled.
• David Durfee added differential privacy noise to scores in newtab score-based selection, anonymizing per-user signals which will alter ranking/discovery behavior on the New Tab page while underscoring privacy guarantees.
• Brendan Birdsong moved newtab score storage to PersistentCache, persisting scores across sessions and reducing recompute/lookup latency so personalized selections are more stable and faster to load.
• Jared Wein fixed more newtab/lib TypeScript errors so 11 more files can be type-checked, enabling type-checking across newtab/lib (11 files) and lowering regression risk for New Tab Page behavior.
• Dre used useWidgetTelemetry in the Weather widget to standardize telemetry for the Weather widget (New Tab Page), improving diagnostic signals that help us find and fix user-facing widget issues faster.
• Maxx Crawford turned off all New Tab widgets in automation with one pref, allowing automation to run with widgets disabled to reduce flakiness in tests that interact with New Tab UI.
• Dre updated the Focus Timer widget to use useWidgetTelemetry, so Focus Timer telemetry now respects widget-level prefs and will avoid sending unguarded pings-privacy impact only, no UI change.
• Nina Pypchenko [:nina-py] fixed transparent New Tab dialogs when the train-hop is applied to Firefox 158 and 159, restoring dialog opacity/CSS so newtab overlays are readable again when train-hop is enabled on those releases.

Picture-in-Picture

• kpatenio fixed a bug on Windows and Linux where clicking a previous control overrides the Space play/pause shortcut.
• kpatenio landed a few patches to make keyboard navigation better when the playback speed control is enabled (Bug 2055070, Bug 2074319).
• As of Nightly 159, the PiP player UI has been updated for Nova. Aside from being visually consistent with Nova, scrubbers and settings panels now have better contrast on High Contrast Mode.

Search and Urlbar

Urlbar

• Dao landed a patch to show the "Search tabs" keyboard shortcut in the search mode switcher menu: 2078113

• Logan Rosen changed the Accel+Shift+A shortcut from the Add-ons Manager to Search Tabs: 1666654. Dao followed up by notifying people who used the old shortcut that it moved and revised the wording of that message: 2077823, 2079208
• James added an option to skip the menu when tabbing through the address bar, in both the address bar and the preferences page: 2064708, 2068609
• Dao fixed a bug so that entering an address in search mode now navigates to that URL: 2036347
• Dao fixed two urlbar.bounce telemetry bugs: 2069403, 2076827
• Caleb fixed a bug where the address bar results dropdown covered the calculator tail150 game: 2077358
• Daisuke fixed a bug where search terms in the address bar moved when pressing Enter or when edited: 2074921
• Dao fixed the search engine button being cut off in the Search dropdown with Nova enabled: 2074871
• Daisuke fixed the search switcher's active button color being too strong with low text contrast in Nova: 2068504
• Emilio fixed the Quick Actions background button missing in the Light theme on Ubuntu in Nova: 2076191
• Moritz continued with MCAB (multi-context address bar) follow-on work: 2078231, 2078658, 2078672.
• Moritz also enabled TypeScript type checking for UrlbarView and UrlbarBaseInput: 2077545, 2077543
• Dao significantly improved the address bar docs, including how to add a new search surface end to end, how results and providers work across the process boundary, and how to debug and log the address bar:

Search

• Caleb fixed a bug where the address bar swallowed the first character typed into it if you typed too quickly: 1953361
• Mark continued working on the new search config, search-config-v3: 2063279, 2063264

Places

• Dao fixed a bug where the bookmark creation/editing panel had no keyboard shortcut mnemonic for the Save button: 1877510

Storybook/Reusable Components/Acorn Design System

• Dialogs in about: pages now match Nova designs more closely

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

• Read aloud [AI feature]: Catch up on your reading list on the go by having Firefox read your articles out loud. In reader mode, you will be able to activate the listening feature, select your preferred reading voice and adjust the playback speed, as well as scrub backwards and forwards, so you can skip to the juicy bits quicker.
• Data consent for extensions: We always want to make sure users know exactly what privacy and data collection settings are required when updating their installed extensions. We are making updates to give you even more visibility and control when reviewing which privacy settings are being modified in an update. That way you can decide whether or not to grant permissions and proceed with confidence.

Firefox for iOS

• Quick Answers [AI feature]: use your voice to ask a question straight from your Firefox homepage and get a quick answer backed by sources in just a few seconds! Your voice, your questions and the generated answer stay totally private.
• Transfer Your Data between Browsers: move to Firefox in a snap by importing your bookmarks, history and reading lists from another browser, all in a few simple clicks! You can also export your Firefox data to other browsers.
• Built-in VPN: After making its grand debut in desktop and Android, built-in VPN is coming to Firefox for iOS! Navigate with extra protection on known networks and public wifi. Select from a large selection of locations, or let Firefox choose the fastest one for you. It's always free and signing up with a Mozilla Account gets you extra bandwidth.

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!
