Firefox Development

(from our goals):


  • [ON TRACK] API-Complete Jetpack
    • Joint with Jetpack team
    • Currently working towards feature-complete beta SDK
  • [ON TRACK] Stand up basic Firefox with Electrolysis

Developer Tools

  • [NEW] Ensure that Firefox 4 ships with a compatible version of Firebug
  • [NEW] Publish a roadmap for integrated developer tools in Firefox, including console, inspection, and js debugging
  • [NEW] Develop long term plan for Skywriter maintenance/support


(there is a team-by-team goals breakdown, as well)

  • [DONE] Javascript performance near or even with Chrome 5 on their benchmarks (within 20% on SS, 30% on V8), with substantial wins on our benchmarks. (Windows, in-browser.)
  • [DONE] Hardware acceleration of video and other HTML and SVG content, as well as user interface, on by default for compatible hardware on all Tier-1 desktop and mobile platforms.
  • [DONE] Fully support the WebGL 1.0 spec, with support turned on by default in a Firefox 4 beta on platforms that support OpenGL or OpenGL ES.
  • [MISSED] security: zero reproducible high/crit > 30 days
  • [DONE] Support multi-process Fennec.
  • [DONE] Support Jetpacks running in separate processes and never blocking the Fennec UI. NOTE: jetpack team hasn't actually integrated this code yet, but it works in small test environments.


  • 123 betaN, final, and Fennec blockers
  • OpenGL composited layers on Fennec update (jrmuizel)
    • Sort of usable now, patches need to be finished before they can land though.
    • Performance work still to be done.


  • Blocker count slowly dropping, now 108
    • Many bug fixes in hand
  • Lots of editor/contenteditable fixes have landed (ehsan)
    • Google Docs features that were disabled for Firefox (spreadsheet formula syntax highlighting) will be enabled for Firefox 4

Tree Management


  • Infallible malloc (added to agenda by Jesse)
    • We talked about this for 10 minutes but decided it need its own meeting, Platform/InfallibleMalloc. Notes have been moved to that meeting's page.
  • Crash Update
    • Crashes on trunk down considerably - ~5/100 active users.
    • In pretty good shape for Beta8
    • Any stability risks in remaining beta8 blockers we should be aware of?
  • Don't forget to file bugs when you see problems in nightlies.
