Release

firefox release summary score: 1.83, Thurs 1.86

• Other than the DOM Quota crash https://bugzilla.mozilla.org/show_bug.cgi?id=1487194, most of the rest of the top 10 crashes as JS related
  • this is a shutdown hang that is one of the classic "can't reproduce locally" issues but we're trying for some diagnostic patches and getting more info. Tom Tung is on PTO ATM.
• Still investigating the Mac specific crash https://bugzilla.mozilla.org/show_bug.cgi?id=1533422
• Reproducible tab crashes https://bugzilla.mozilla.org/show_bug.cgi?id=1521370, overall #12

Mobile

• Crash rate is calculated based on usage hours (the time Firefox is actively used).
• Usage hours will be significantly lower on Fennec than on desktop Firefox, so we can't compare mobile rates to desktop rates.
