Beta

https://metrics.mozilla.com/public/sguha/mc2/beta.html

• no unexpected change in 70.0b13
• overall the state of 70 beta is looking good in terms of stability - browser crashes are dominated by issues on shutdown and content crashes by oom/jit/gc crashes as we're used to see

Release

https://metrics.mozilla.com/public/sguha/mc2/release.html

• Graphs show that large spike in printing crashes in https://bugzilla.mozilla.org/show_bug.cgi?id=1585109 is gradually declining
  • Microsoft pushed out a fix

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.
