  • 10 hardblockers

  • The fixes we have for DirectWrite I/O causing huge startup times have all landed (bug 602792). If there are remaining issues, please open new bugs.
  • Repeating our call from last week: People who experience the following hardblocker bugs, please contact Joe or Bas:
    • bug 603134 - OS X only - Firefox/Minefield doesn't render any content in new windows until you move the window. This can also manifest itself as random parts of the window refreshing at inconsistent times.
      • This is a Mac OS X bug. We're trying to work out what hardware is affected by it.
      • Please contact joe on irc or if you see this.
    • bug 603793 - Windows only - Menus disappearing, often on submenu mouse over.
      • We can't reproduce this and don't know anyone directly who does.

  • Blockers down to 49 (14 hard).
    • Scary stuff remaining: border-radius clipping
  • Also looking into scrolling perf regressions
  • A pretty invasive change to plugin rendering is in the works, hope to have it working around the end of this week, reviewed and landed next week. Will definitely need beta coverage.


  • 20 hardblockers left. Good progress in the bulk of those (some plugin bugs desperately need attention, working on that).
