Firefox 4 Beta 7

Firefox Development

(from our goals):


  • [CARRY OVER] API-Complete Jetpack
    • Joint with Jetpack team
  • [NEW] Stand up basic Firefox with Electrolysis
    • Joint with Platform
    • UI may not be functional, should launch and open a web page.

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


  • Goals: Real list found here. Quick overview:
    • [ON TRACK] Finish Firefox 4 blockers.
    • [ON TRACK] Support Firefox Team to stand up a browser on Electrolysis.


  • Workin’ on blockers.


  • Not much change since last week


  • In not-JS-but-almost-JS news, work proceeds on exposing DOM properties as proper ES5 accessor properties, with function-valued getter/setter functions (bug 560072); has most-of-the-way semi-hackish patch, but not yet clear whether the more principled fix is preferable

Tree Management

  • Need a 3 hour downtime to update talos and install MozillaDongle Mark II/III ™ on the snow leopard machines.
    • today? this week? next week? after “go to build” of which release?


  • [beltzner] Should we ship beta 7 off mozilla-central default or the b7 relbranch created on October 6th?
    • since October 6th, over 300 blockers and over 500 non-blockers have landed on mozilla-central
    • we have not had nightly testing on the b7 relbranch, and the compartments work has never been on that branch
    • prior to the compartments landing, QA had declared the b7 relbranch content to be stable
      • decision was to ship beta7 off mozilla-central
      • tree will be locked to beta 7 blockers immediately (and fennec b2 blockers)
      • teams to re-triage beta8 blocker list to identify bugs that need to block beta7 (new regressions since the branch point)
  • [smooney] A few new crashes in the past week we would like to have triaged.
