Schedule Update

  • Beta 6 desktop and mobile should be released today
  • Thursday and Friday are a U.S. holiday
  • Beta 7 desktop build/release Thurs/Friday (Sylvestre, Florin & Andrei will cover this)
  • Should we do a beta 7 fennec release because of battery drain issue?
    • And possibly a 42.0.2 fennec.
  • Beta 8 will build/release on Tues/Wed Dec. 1/2 next week.
  • Romanian holidays on Nov. 30/Dec 1 so Softvision will be out.
  • no KaiRo next week, still working on a full plan to cover



  • Overall rate: 2.5 – browser: 1.5, content: 1.0 – red, slightly lower than last week
    • largest crashes are with a11y+e10s, we need to make sure to exclude that audience from beta experiments (a patch for that is in bug 1226487)
    • patches also coming to not activate e10s on dev edition when a11y has been activated recently (bug 1198459)
  • bug 1219529 is >1% of overall crashes, has a patch verified on nightly and an uplift request
  • bug 1218032 (nsContentIterator::NextNode) is still very visible in stats, but not happening with builds of Nov 18 or newer due to backout in bug 1224101


  • Overall rate: 1.1 – yellow, similar to last week
  • bug 1226400 (dom::FontFaceSet::Load) is 2% of 43.0b5 data and #2 Top Crash Score – this is happening across channels, platforms and even Android.
  • bug 1222933 (mostly Ad Muncher) is 1.5% and #1 Top Crash Score
  • bug 1222819 (Orbit Downloader) is #3 Top Crash Score
  • bug 1227221 (Flash beta 20 hangs) has been causing the Flash hang rate on beta to roughly double, Adobe says they found the issue are are releasing a newer beta today – we’ll watch data as they plan to ship Flash 20 very soon.


  • Overall rate: 0.9 – green
  • bug 1222933 (mostly Ad Muncher) is #1 Top Crash Score
  • bug 1226400 (dom::FontFaceSet::Load) is 1% of 42.0 data (and rising)
  • bug 1224549 (Java plugin hangs) increased the overall count of plugin hangs on release by ~25% and pushes Java users to use older, insecure Firefox versions
  • bug 1221448 (Java plugin crash) is still a significant portion of plugin crashes overall and makes lives suck for Java users, but is fixed in the very newest Java 8 build, according to both Oracle and our crash data. (




  • saw some delays today with build getting onto beta-cdntest channel, will run update tests after this meeting
