New Tab Page

  • No updates (I’m also out today)

NodeJS

Password Manager

PDFs & Printing

  • Mark has a patch to support submitting the print form immediately after opening with Enter bug 1666776
  • We’ve been ramping up our test coverage

Performance

  • Skeleton UI

    • Doug has patches up for review for animating it and is continuing to work on fixing bugs and oddities with it. Eg. ensuring it correctly handles maximized windows, which is hairier than expected.

    • Emma has been looking at getting the bounds of the urlbar rect for the early blank window paint

    • (Reminder: set the pref browser.startup.preXulSkeletonUI to dogfood this. Windows-only.)

  • As a team we’ve started discussing problems and paths forward for BHR.
  • Gijs has a patch for slow script telemetry from the parent process. This is to report on telemetry the cases where we would have previously shown a slow script dialog, which isn’t useful for the parent process.
  • Gijs landed more IO-off-the-main-thread work for downloads

Performance Tools

  • You can name the profiles by clicking on the top left profile title now.

  • Florian added a GetService marker that shows when an xpcom service gets first instantiated. The marker text only shows the cid; the contract id, or service name is shown in a label frame in the stack. Example profile: https://share.firefox.dev/2SutTKn

  • Our contributors made some improvements on the track context menu:

    • Track context menu now shows only the right clicked process instead of showing everything. (Thanks adityachirania!)

    • Added a Hide "Track Name" to the track context menu. (Thanks CipherGirl!)

Privacy/Security

Remote Protocol (Chrome DevTools Protocol subset)

Search and Navigation

  • The team is focusing on new opportunities related to vertical search, experiments will follow.

  • Consolidation of aliases and search keywords - Bug 1650874

    • UX working on better layout of search preferences

    • Development is temporarily on pause to concentrate on higher priorities

  • Urlbar Update 2

    • Polishing the feature to release in Firefox 83.

    • Clicking on the urlbar opens Top Sites also in Private Browsing windows, unless they have been disabled in urlbar preferences. Bug 1659752

    • Search Mode will always show search suggestions at the top. Bug 1664760

    • Tab-to-search has been enabled in Nightly! When the urlbar autofills an origin having an installed search engine, users can press tab or down to pick a special shortcut result and enter Search Mode. Bug 1667470

WebRTC UI

  • Device sharing state indicator icons have been added to the system tray on Windows:

  • The global sharing indicator now only displays if the user is sharing their screen, and the microphone and camera mute toggles have been hidden by default.

    • You can turn these back on by going to about:preferences#experimental, and checking “WebRTC Global Mute Toggles”.

    • These are experimental because many sites don’t pay attention to the “muted” event, so they don’t update their UI when mute state is set.

  • The global sharing indicator is currently slated to ride out in Firefox 83.

Bookmarks & Downloads

This week I learned

  • [Luca] If by running `mach static-analysis check path/to/your_new_file.cpp` locally you do not get any of the results you see on phabricator, then it is likely that the "compile_commands.json" file you have locally is outdated (apparently `mach static-analysis check` does not currently check that automatically):

    • An easy workaround is to just remove the "compile_commands.json" file (or manually regenerating it using “mach build-backend -b CompileDB”) and run `mach static-analysis check ...` again, the json file will be recreated and the cpp file should now be checked as expected.
