Firefox Developer Tools



  • Work on off main thread compositing has begun, with Ali Juma and Benoit Girard taking point.
    • Our initial goal is for this to be Android only, but in order to accomplish that goal, we're going to also implement OMTC on OS X.
      • We expect most of the fundamental issues to be cross-platform, and development on OS X is easier than Android. But a releasable product on Android is our only goal for this work.
    • We plan to use Helgrind on OS X to detect thread issues, which may need some work from the Valgrind team.
    • We will also likely need some help from the A-team in developing a general browser usage test suite.
      • A sort of browser usage fuzzing, to detect edge cases that break down with OMTC.


  • The tracejit is history; RyanVM has closed about five bazillion bugs (~300ish?) that were relevant only to the tracejit.
  • The tracejit has been given an honorable discharge:
    • It's been replaced by JM+TI, and removing the tracer will help simplify things, which speeds along further perf improvements.
    • Let us know if you see any bits left, there's still some cleanup going on.


  • font size inflation for mobile landed: see blog post. Feedback requested (see blog post) on how it interacts with individual Web pages (i.e., whether it's picking the right things to make larger and the right things not to make larger)




  • Progress on telephony. Hope to have basic dialing by the end of the week
  • Sending/receiving SMS landed for android
  • Lots of progress on IndexedDB. Getting close to "done"


  • Hopefully landing a number of NSS and SSL/TLS changes today. Should be good for performance and some changes are pre-requisites for SPDY.
  • Hopefully landing SPDY (pref'd off) tomorrow.
