Schedule Update

  • 43 beta 4 will release today
  • 43 beta 5 Thurs/friday.
  • Coverage over American Thanksgiving (build and release beta 7)
  • Discussion about a 42.0.1 dot release for Android:
    • Bug 1209612 – top crash
    • Bug 1198663 – top crash
    • Bug 1221228 – Android 6.0 reboot because of fennec (fix on Nightly has been verified by multiple users)
    • I would like to go ahead with this soon (Kevin)
    • bug 1222933 (mostly Ad Muncher) is #1 Top Crash Score (KaiRo suggested we take this one too)
    • I can start preparation for a dot release (liz)



  • Overall rate: 2.8 (browser: 1.6, content: 1.2) – red
  • bug 1224101 (nsContentIterator::NextNode) is 12.3% of browser+content crashes, approved last week, still not landed.
  • bug 1198765 / bug 1210821 (ipc::FatalError in jsipc::PJavaScriptParent::Read) combines to 11.8%


  • Overall rate: 1.0 – yellow (almost green)
  • bug 1215970 (Skype Click-toCall) is still 3.1% of 43.0b3 data, the compatibility change didn’t help
  • bug 1222933 (mostly Ad Muncher) is 1.9%
  • bug 1182197 (Promise Settle) is 1.8%, uplift was approved before b3, but still didn’t land for b4.
  • Crash-stats graph still looks wonky – is data missing? (Nevermind, looks ok on hard refresh)


  • Overall rate: 0.9 – green
  • plugin crashes and hangs did rise significantly (~30%) with the 42 release – looking back at data, this can be made out with the beta 42 uplift as well.
  • Win10 stats look normal now, the high volume of NVidia crashes is gone.
  • bug 1222933 (mostly Ad Muncher) is #1 Top Crash Score


  • still really bad crash rates all over, red for all channels
  • bug 1209612 (GLLibraryEGL::InitExtensionsFromDisplay) is 6% of 42.0 crashes and a startup crash
  • bug 1198663 (layers::ImageContainer::GetCurrentSize) is 7% of 43.0b2 crashes
  • bug 1196299 is quite high on beta as well, x86 APKs on ARM device



  • some more big uplifts coming, apple system font
  • windows touch screen (extra QE for this would be good)
  • Windows 10 edge migration bug (note: this affects the latest Insider builds, while the release version of Windows 10 (build 10240) is unaffected.)
  • [releng / jlund] update_verify steps for linux{32,64} are now nearly failing at everything because of gtk3


  • Disabling a/b test on Android – requires a code change – proposed for next week, see r-d
  • Silverlight for Win64 support:
