Notices / Schedule

Please focus on bugs tracked for FF15 and FF16

  • FF14.0.1 was unthrottled last Thursday, based upon early post-release feedback
  • FF14.0.1 post-mortem held this morning – discussion focused on plugins and update uptake
  • FF15 beta 3 (of 6) going to build today, will be released before the end of the week

Firefox OS

  • Milestone 5 – focusing on wrapping up the feature work that’s left, polishing UI, bug fixing and performance optimizations
  • Gaia app updates are at https://etherpad.mozilla.org/gaia-meeting-notes
  • Identity and WebAPI updates are below.
  • Technical Release Plan partially signed off after driver meeting last week, more details soon
    • Focus was on short-term decisions (branching, updates, testing, etc.)
    • ESR17 will be the Gecko basis for B2G v1. See email to enterprise list and dev.platform soon.
  • Blockers for internal dogfooding and external testing have been identified and are being prioritized
  • Hardware dogfooding now has all interested parties involved (including IT and engagement)

Firefox Development

  • Social: bug 764869, bug 764872, bug 773351, bug 770695: big pieces of the work that makes Social actually semi-usable have landed. That means that you can test social features using “MoTown” in Nightly builds, by setting social.enabled = true.
  • bug 769960 landed this weekend, big cleanup of safe browsing front-end code by dolske, paves the way for additional cleanup (bug 775851) and better code re-use from mobile and other apps
  • (catlee) What’s the status of the stub installer work? When are we aiming to land this? What changes are required for RelEng?

Firefox Developer Tools

Add-on SDK

Performance

  • Nick Hurley blogged about his research into cache usage results
  • According to telemetry, 10-20% of start-ups feature cache nuking. Brian Bondy used telemetry to investigate causes for cache purges in bug 774146.
  • And Brian landed a fix to lower IO priority of nuking our cache (bug 773518).
  • Tim Taubert made our new tab animation more pleasant (bug 716108).
  • Tim also landed a fix to halve jank caused by thumbnail capture (bug 774811), which should result in a better tab-switching experience.
  • Jon Coppeard enabled incremental GC sweeping (bug 729760), which should result in slightly smaller GC pauses.

GFX

  • Azure content (currently enabled for Direct2D, i.e., hardware accelerated Windows Vista and 7) is being turned off for Firefox 15 (currently in beta) due to regressions.
    • It’s staying on in 16, though.
    • The new 2D API is still our future, it’s just not ready for prime time yet.
