Blocker Report

Firefox 4 Beta

Firefox 3.6.10

Firefox 3.5.13

Firefox Development

(from our goals):

  • [ON TRACK] Feature complete Firefox 4
    • [DONE] Switch to Tab
    • [DONE] App Tabs - Scope for 4.0 reduced (non-global), near feature complete.
    • [DONE] Extension Manager - Bug list is converging, still a lot of work to do.
    • [DONE] Web Console
    • [ON TRACK] Notification UI - Geo and EM notifications done, http auth next.
    • [ON TRACK] New Theme - Windows and Mac good, Linux catching up now
    • [DONE] TabCandy Panorama
    • [AT RISK] Silent updates on Windows
    • [DROPPED] Inspector
    • [DROPPED] Account Manager - WIP patches posted, but we can't contain the review load and code risk.
  • [AT RISK] Dirty profile startup within 20% of clean profile startup (modulo extensions, plugins; on windows)
    • Current status: Lots of data has been collected and analyzed, but no solid conclusions have shaken out.
    • Details page
    • Shawn has an updated blog post. Read it for more info.
    • Bugs on file that help:
      • Excessive cookie i/o bug bug 572223 (fixed)
      • Session Restore negatively impacts startup time based on the number of tabs loaded bug 582005
      • Suboptimal SQLite page size bug 416330 (fixed)
      • Provide a global VACUUM component bug 541373


(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.


JM looking good on TM tree, a few blocking things remain: bug 592960, regex problems. Some possible problems related to lack of compartments.


  • Accelerated compositing using Direct3D 9 (on Windows) has been turned on by default on mozilla-central!
    • If you notice problems with Direct3D 9, please report them in Bugzilla. You will want to accompany your bug report with the Graphics section of about:support, so we can more easily work out what's wrong.
    • To narrow down whether a problem is caused by Direct3D 9, you can set the about:config pref layers.accelerate-none to true, and restart your browser.


  • calc() basically done (see dbaron's blog)
  • Q3 goals done
  • Still targeting feature freeze: SVG images, async plugin painting
  • document presentation swapping on track


  • Virtual properties (bug 499201) support at risk for beta5 :(
