Project Updates

Add-ons / Web Extensions

Addon Manager & about:addons

• Thanks to emilio’s patch, starting from Firefox 86 the zoom levels for the extensions options pages embedded in the about:addons tabs should be set as expected - Bug 1398481.

WebExtensions Framework

• Sonia contributed a small but nice cleanup by removing the extensions.webextensions.tabhide.enabled preference. Thanks Sonia!
• Fixed a regression (introduced by Bug 1638422) related to making sure that webRequest StreamFilter is disconnected after a redirect - Bug 1683189
• Fixed crash in webRequests StreamFilter on view-source requests (Bug 1678734)

WebExtension APIs

• Allowed redirect URI to be set to a loopback address in the identity.launchWebAuthFlow API, needed to allow extension to successfully integrate oauth authentication for some common web services (e.g. google services) - Bug 1635344 (landed in Firefox 86, uplifted to 85, will also be uplifted to 78 ESR)

Developer Tools

• Error count button in the Toolbar - shows amount of errors on the current page.

Screenshot online

• Performance fix for the Browser Console (bug)

• Planning

  • DevTools Fission M3 - Reaching Feature parity with pre-Fission state.

  • WebDriver BiDi - a standardization project to specify a bidirectional, automation-focused, protocol for the future.

Lint

• globalThis is now fully enabled for ESLint. Some support was previously enabled, but the definition for the global was missing.
• Whitespace linter now also fails for missing whitespace at the end of files.
• no-async-promise-executor is now enabled everywhere in the tree.
• Don't forget: There's a "Lint and Formatting" ([#lint:mozilla.org]) channel on Matrix for all your lint and formatting questions.

New Tab Page

• New personalization for sponsored content just went to nightly, and is having a rollout for 84/85.

  • This version mostly differs from the old one by building a topic based interest profile instead of matching domains.

Password Manager

• (read only unless someone else can take it, :sfoster has a conflict)
• Thanks for Kenrick85 for their continued contributions, recently landing bug 1579108 to fix alignment in the about:logins item/edit form layout.

• Dlee and tgiles have been cleaning up about:logins with a series of patches landed:

  • Bug 1678633 - A blank page is wrongly displayed on the “about:logins” page after signing out from Firefox Sync and checking the option to delete all data

  • Bug 1679131 - Remove all confirmation modal - icon and close button icons can be dragged

  • Bug 1683615 - about:logins - in-page focus jumps on the meatball menu when navigating by keyboard

Performance

• mconley completed an analysis on the performance impact of using built-in fonts for proton
• gijs fixed a toolbar flicker bug
• gijs continues to investigate the DOM size for potential performance wins
• dthayer propagated annotations from the BHR ping through the processing job and worked with florian to display annotation information in his BHR exploration tool

Performance Tools

• Improved accessibility in the network chart.

Picture-in-Picture

• We have a new set of students from MSU starting soon! mhowell and mtigley will be mentoring them. This is the metabug for their work.

Proton

• Watch this space! Proton is a UI refresh effort that’s just starting to get off of the ground. Expect stylistic and content changes to the toolbars, menus, tabs, etc.
• Here’s the metabug. All work will fold under it. And here’s the wiki page.
• There’s a browser.proton.enabled pref, but it’s early days, so this doesn’t do anything right now. As Proton-associated changes land, they’ll be keyed off of this pref.
• Some things we think we can start working on and landing sooner, so we’re working on that as designs are solidified.

Search and Navigation

• Fixed a performance problem when a very long search history entry was suggested. Bug 1682434
• Fixed a race condition where pressing ESC may not always exit search mode. Bug 1677325
• Fixed a bug causing Bookmarks, Tabs, History buttons to disappear from Search Preferences when restoring defaults. Bug 1681818
• Removed most browser.urlbar.update2.* prefs in Firefox 86, a few were left for features that are still under exam. Bug 1665049
