Highlights

• James from the Search team has been working on persisting the search term in the address bar after you do a search in it. It is now enabled on Nightly (see bug 1802564). Try it out, file bugs if you see them and let us know if you have any feedback.
  • 

    In Nightly, search terms in the URL bar persist after pressing Enter!

• Evan, one of the students working with us from CalState LA, landed a patch that adds a new Opera GX migrator
  • It’s currently disabled by default, but can by enabled by setting `browser.migrate.opera-gx.enabled` to true in about:config
• For WebExtension authors: thanks to Alex Ochameau’s work in Bug 1410932, starting from Firefox 110 the errors raised from extension content script contexts will be logged in the related tab’s web console
• The screenshots component now respects the setting “Always ask you where to save files” when downloading screenshots. Set `screenshots.browser.component.enabled` to true to use this feature.

Add-ons / Web Extensions

Addon Manager & about:addons

• Improvements to “all sites” optional permissions support in the about:addons permissions view – Bug 1778461

WebExtensions Framework

• Use https by default in MV3 extension requests (enforced through the default MV3 extension CSP) – Security and privacy related restrictions Bug 1797086
• Unified Extensions Button got some more minor tweaks, fixes and additional test coverage – Bug 1802366, Bug 1802925, Bug 1803650, Bug 1801336, Bug 1800109, Bug 1801514, Bug 1802562
• Fixed a race between the extension manifest parsing and the extension startupCache population on extension startup – Bug 1791370

WebExtension APIs

• Thanks to Gregory Pappas for contributing:
  • implementation of the additional Omnibox onDeleteSuggestions API event Bug 1478095 – Implement `onDeleteSuggestion`
  • Exposing securityKeyLength in WebRequest SecurityInfo details Bug 1778473 – webRequest API: Add key length property to SecurityInfo object
• As part of the ongoing work on the declarativeNetRequest API:
  • Introduced support for the urlFilter condition (Bug 1745759), the modifyHeader action (Bug 1797404), the “redirect.trasform” rule property (Bug 1801870) and static rulesets (Bug 1745763)
  • Restricted tabIds and excludedTabIds conditions to session rules – Bug 1804464
  • NOTE: declarativeNetRequest API is currently only enabled when the “extensions.dnr.enabled” pref is set to true, and only exposed to MV3 extensions.

Developer Tools

DevTools

• Zac Svoboda improved the color of errors in the JSON viewer (bug)
• We added scrollend event in the Debugger Event Breakpoints panel (bug)
  • 

    Want to hit a breakpoint as soon as scrolling ends? Now’s your chance!

WebDriver BiDi

• Julian fixed a bug in webDriver where WebDriver:FindElements would not retrieve elements if the Firefox window was behind another app’s window (bug)
• Sasha added full support for session.subscribe and session.unsubscribe commands (bug, spec)
• Henrik added support for serialization of Node objects (bug)
• James implemented the browsingContext.captureScreenshot command (bug, spec)

Desktop Integrations

• We now have automated tests running against MSIX packages
  • mochitest-media for now, browser-chrome in the near future, and hopefully xpcshell

ESMification status

• Please consider migrating your components if you haven’t already. Don’t forget actors as well.
• ESMified status:
  • browser: 46.4%
  • toolkit: 31.62%
  • Total: 43.6% (up from 41.3%)
• #esmification on Matrix
• Migration Document (with a walkthrough!)

Lint, Docs and Workflow

• A new rule has been added to disallow the single-argument form of Cu.reportError. console.error should be used instead.
  • There is a meta bug for the work to remove (or replace) Cu.reportError completely.
  • Replacing the two argument form will come later as it still needs some investigation.

Migration Improvements (CalState LA Project)

• Steven landed a patch that lets us open up the migration dialog in a tab modal
• mconley added some infrastructure for a new migrator wizard, and also wrote a bunch of documentation for the students who are going to be working on it
• The students are now on exam / winter break and will hit the ground running again in late January.

Performance Tools (aka Firefox Profiler)

• Made searching in markers more generic. Now any property can be a searchable property, the gecko engineers can now change this themselves without changing the frontend. (PR #4352, Bug 1803751)
• Landed some changes in the category colors (more contrast, brown is now really brown, added a new magenta color).
• Changed the treeherder performance regression template to output the before and after profile links for each regression (PR #7588)
  • 

    This will make it much easier to immediately jump in and start analyzing performance regressions.

Search and Navigation

• [James] fixed context menu search terms to be displayed in the address bar for certain engines. Bug 1801602
• [Drew] has refactored quick suggest telemetry tests. Bug 1804807
• [Drew] did a bunch of refactors to support row buttons in all row types. Bug 1803873
• [Dale] updated a few strings for the quick action buttons. Bug 1783153
• [Dale] turned off quickactions on zero prefix by default. Bug 1803566
• [Stephanie] fixed a bug so we can record search telemetry from different search engines who have the same underlying ad provider. Bug 1804739
• [Mandy] fixed a bug where search engine order was modified. Bug 1800662
• [Standard8] has refactored multiple files in search:
  • Bug 1804520 – removed the callback argument for SearchSuggestionController
  • Bug 1803911 – replace Cu.reportError calls in newtab

Storybook / Reusable components

• Our Storybook is online
  • Currently a manual deployment process, will look into automating it soon
• moz-button-group element landed in about:logins, standardising/simplifying a few modal buttons. See Bug 1792238 and Bug 1802377
  • Before:
    • 

      This is how it has looked up until now, which is inconsistent with our other dialogs.

  • After:
    • 

      This is how it’s supposed to look. Thanks, moz-button-group!

• Emilio updated stylesheet loading to be sync for our privileged shadow DOM, avoiding flashes of unstyled content (FOUC) Bug 1799200
