Project Updates

Accessibility

Add-ons / Web Extensions

Addon Manager & about:addons

WebExtensions Framework

• Fixed an issue that was preventing Firefox from fully unregister extensions that did fail early during their startup (Bug 1651844)

WebExtension APIs

• dw-dev contributed a fix to the downloads API to ensure that the ‘Save As’ dialog will use a file filter derived from the filename set by the extension in the download API call (Bug 1651175). Thanks to dw-dev for contributing this nice enhancement!
• Fixed a regression on the downloads API when used in private browsing mode on an extension-created blob url (originally introduced in Firefox 79 by Bug 1579911), the fix has been uplifted to Firefox 79 (Bug 1649463)

  • print.tab_modal.enabled

Performance

• bigiri is fixing the last few dozen failing tests with porting ASRouter to JSWindowActors
• The DLL prefetch experiment is still underway. The team hopes to have a sense of the impact on user startup times after we’ve collected more data.

• dthayer has moved Nightly to Stage 3 of FastShutdown

  • 445x218px

  • A really nice dropoff in shutdown times!

• emalysz has made more panels lazy

  • 522x152px

  • Seeing a really nice dropoff on twinopen Talos times! We’re definitely trending in the right direction.

• Gijs has landed probes for the slow script notification warnings

• Another shoutout to the IOUtils module by keefer!

  • Still somewhat in early stages, but usable enough to do OMT reading, writing and stating of files!

  • Organizing document

• mconley is soliciting feedback on a plan for making it easier for the front-end to annotate BHR reports

Performance Tools

• Changed the UI to use sample counts, and added explicit support for traced profiles.
  

601x244px

• Renamed IPC message tooltip labels to be more descriptive.
  

IPC Speed -> IPC Send Duration
IPC Latency -> IPC Recv Latency

• Started to use the appropriate time unit in the marker chart.
  

601x173px

Picture-in-Picture

• Recently landed patches to experiment with new toggle variations and placement
• Glitch prototype

• Toggle experiment preferences:

  • media.videocontrols.picture-in-picture.video-toggle.mode

    • Default = -1
    • Mode 1 = 1
    • Mode 2 = 2

  • media.videocontrols.picture-in-picture.video-toggle.position

    • “right” = right side (default)
    • “left” = left side

  • media.videocontrols.picture-in-picture.video-toggle.has-used (only affects Mode 2)

    • true - the user has used Picture-in-Picture before in 80+
    • false (default) - the user has not used Picture-in-Picture before in 80+
