Project Updates


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)

Performance Tools

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


  • Renamed IPC message tooltip labels to be more descriptive.

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



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


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

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

Search and Navigation


Address Bar:

User Journey


  • Holding the new WebRTC global sharing indicator to Nightly for now while we sort out default placement.
  • We’re going to ship it on in an experiment in Firefox 80 on release to get a sense of how it’s being used in the wild
