Stability

• Filed a few new bugs after the recent Socorro work
  • https://bugzilla.mozilla.org/show_bug.cgi?id=1477754
  • Crash ranks seems to start at "0" now instead of "1"

Nightly

firefox nightly summary score: 5.82, last week 3.84

• Overall rate looks pretty good
• https://wiki.mozilla.org/NightlyCrashTriage/2018Q3 has a summary of the latest nightly crash bugs filed
• Nothing else specific to call out

Beta

firefox beta summary score: 3.62, last week 3.22

• https://bugzilla.mozilla.org/show_bug.cgi?id=1464938 continue to be visible in b10. Kris was pinged 13 days ago in we haven't yet received a response - 11.5% of browser crashes
• Strange single installation crash - 2600 crashes? Maybe we should try to narrow down what caused this?

Release

firefox release summary score: 3.16, last week 2.65

• Nothing new to report since last Thursday
• Looks as if top Mac release crash https://bugzilla.mozilla.org/show_bug.cgi?id=1471892 is fixed for 62

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.

• Release

fennec release summary score: 28.65, last week 28.83

• • https://bugzilla.mozilla.org/show_bug.cgi?id=1476319 continues to rise on release. Work still ongoing

• Beta

fennec beta summary score: 31.01, last week 33.27

• • Local storage crash is #3 - https://bugzilla.mozilla.org/show_bug.cgi?id=1475218.

• Nightly

fennec nightly summary score: 46.29, last week 42.85

• • [wlach] note that the true crash rate over the last few days is actually even higher @ ~130 (the summary score is a reflection of the nightly rate over the entire release) -- https://data-missioncontrol.dev.mozaws.net/#/nightly/android/main_crashes
  • Overall rate is a bit higher due to some crash spikes related to the API 26 work. See bugs below
  • https://bugzilla.mozilla.org/show_bug.cgi?id=1477041 continues to be the top crash and is now assigned
  • #2 https://bugzilla.mozilla.org/show_bug.cgi?id=1476710 is also assigned
  • #3 top crash https://bugzilla.mozilla.org/show_bug.cgi?id=1476424 has a reviewed r+ patch
