Firefox Development

Firefox OS

Firefox Developer Tools

Add-on SDK

  • Releasing a 1.8.1 to fix a small problem with the last release
  • Work is ongoing on developing a repacking script that should work for the majority of AMO add-ons using old SDK versions


  • This week's Snappy summary
  • Jared Wein discovered that about:home was surprisingly expensive to load. He sped up the page by an estimated 30% in bug 765411.
  • Alex Crichton added ability to profile JS in bug 761261.
    • Benoit Girard is adding labels to the profiler to expose JS profiling info in bug 707308. Same functionality will also allow us to add URLs to the stacks. This means that in addition to seeing what Firefox is busy with, the profiler will now provide context on what caused the processing. This is huge. Benoit also improved profiler timing data in bug 769989.
  • Nicholas Chaim updated his addon to track system IO usage while starting Firefox. It's now on AMO and automatically uploads results. If you suffer from slow Firefox startups, please help us identify common IO hogs by installing his addon. Please encourage friends with slow startups to do the same.



  • FIXED: bug 769754 Crash while using the debugger. This impacts Aurora and should get uplifted (Flags: approval-mozilla-aurora?). - Jim Blandy

  • css3-flexbox and css3-values likely to go to Candidate Recommendation very soon

    • bug 767936 - Use Element* as the cache key for CanvasImageCache. (bz)
    • bug 765906 - synthetic bold should be used where appropriate with system fallback fonts (jkew)

Tree Management
