These Weeks in Firefox: Issue 24


Friends of the Firefox team

(Give a shoutout/thanks to people for helping fix and test bugs. Introductions)

Project Updates


Activity Stream

Browser Architecture

  • Formed a team to do a design review on XBL removal plans
  • Sent out a front-end developer survey
  • See our most recent newsletter!

Electrolysis (e10s)

  • Improvements to memory usage means we might consider increasing the content process limit at some point in the future. Check out erahm’s blog post!

Firefox Core Engineering

  • Update agent work has begun, starting with the downloader, which plans to spin off the update download as a background process (so the update continues even if the user’s session ends). This is aiming for Firefox 58.
  • Optimized data in crash reports and crash ping processing have landed in Firefox 57 (even though they were targeted for 58).
  • JAWS client version has been added to the updater URL, just in time for Firefox 56.

Form Autofill


  • First Firefox iOS 9.1 Beta is in QA and will ship soon with a modest list of small fixes
  • First Firefox iOS 10.0 Beta is currently being prepared. This is our Photon UI release. We expect to have it on TestFlight for our Beta testers very soon.
  • The Firefox iOS team’s focus for the upcoming release is on Photon, Telemetry and Stability




  • Prathiksha finished up a few polish bugs on permission management, we consider it MVP-ready and it’s shipping in Firefox 57!
    • Showing the DOM permissions UI under about:preferences.

      Who’s in control? You are.

Search and Navigation

Sync / Firefox Accounts

  • Edouard is implementing native “toast” desktop notifications for Windows 8 and 10!
  • Kit is porting structured bookmark application to Desktop from iOS. Instead of applying downloaded bookmarks directly to Places, we’ll stage them in a separate buffer, run a tree merge, resolve conflicts, and then update Places in a single transaction.
    • This will fix a class of persistent bugs around random dupes, moves, reordering, incorrectly merged folders, interrupted syncs, and devices falling out of sync with the server.
  • Thom is removing more event loop spinning from Sync.
    • This should prevent Sync from spuriously appearing in performance profiles, unless it’s actually janking the browser.
  • Edouard landed a more responsive Sync animation if you click “Sync Now” at startup before Sync has loaded.

Here are the raw meeting notes that were used to derive this list.
