  • FF3.6 to 12 automatic updates with add-on compatibility checks went out today for the security of users on these older versions of Firefox

Firefox Development

  • WebApp runtime support on Linux: great work by Marco Castelluccio to get that completed and landed for Firefox 15 (bug 744193, bug 745018)
  • WebApp runtime fixes to enable WebGL, geolocation, and offline cache in the web app runtime: bug 748214, bug 749459, bug 749029
  • PDF.js:
    • bug 748924: updated pdf.js version, new interface and bug fixes
    • bug 752676: added a way to toggle pdf.js on/off
    • Uplifted to Aurora (Firefox 15 train), hoping to get some more feedback
  • bug 742047: Andres and ttaubert are refactoring session storage, first step towards reducing blocking pauses and performance impact (tracking bug 669034)
  • bug 758812: browser.js split up into smaller pieces, see dolske's blog post for more details
  • theme work:
    • mixed content icon updated to be less obnoxious (bug 755429)
    • updated loading/connecting throbbers (bug 760322)
  • inline autocomplete fixes:
    • bug 720081
    • inline autocomplete has been uplifted to beta

Firefox Developer Tools

  • Responsive Mode landed.
  • Layout View turned on.
  • Loads of debugger fixes landed last week, feedback wanted.
  • Perf improvements on the web console.

Add-on SDK



  • This week's Snappy summary.
  • Necko team landed a fix to the cache that should freeze the UI thread less during reads (bug 722034).
  • Bill turned on incremental GC again (bug 735099).
  • Brian landed a way to bypass the windows prefetch service via our privileged silent update service, which should improve start-up time (bug 692255).
  • Brian has instrumented our event loop to measure the extent of Firefox lag when responding to user events (bug 759449). This is different than measuring general event-loop lag in that it focuses on lag that the user will actually notice. Interested? See the EVENTLOOP_UI_LAG_EXP_MS histogram in our Telemetry dashboard. This shows a regression starting on June 2nd, any ideas on what landed that would've caused a regression?
Help Wanted
The necko team is looking for help to determine the optimal disk cache size. Please see Nick’s post.




  • Fennec 1.0 Blocking Bugs

  • Changed category to Media :-)
  • Initial WebRTC landing as soon as reviews are in; will warn people and try to land early in a day EDT to avoid too much activity.
  • Desktop getUserMedia implementation close to ready (once we have WebRTC on m-c); will enable a lot of demos/etc.



  • Multiprocess IndexedDB landed. (Blob support still missing).
  • FileHandle support landed. We now have low-level file-CRUD support! Prefixed since we're still working on standardization.


  • Firefox 13 shipped with SPDY enabled by default!
  • Major cache performance improvements have landed - bug 722034 and bug 746018.




  • Fullscreen support for plugins on Gingerbread and Froyo
  • Reader mode
  • New address bar layout


  • The nightly run of FF on mac with a11y turned on turned up issues so we have turned a11y back off while we sort them out (probably via whitelisting bug 759736).
  • Mobile Firefox accessibility is full speed ahead.
  • We're planning a work week in Toronto August 20-24th where b2g will be an area of activity.

  • No changes in Crash Ratio was expected for this release as there was no real crash fixes placed in. This was stated last week.
  • Beta 4 shows spike at the beginning because of low ADU (: reason why we had 18.75 % crash in beta 4 was because of 3 crashes w/ 16 users per 100 adu.
