  • frozen fennec: 65 has a tentative fix, but caused a crash; droeh's actively working on it

Stability

• Filed https://bugzilla.mozilla.org/show_bug.cgi?id=1510293 for the missing Windows symbols

Nightly

firefox nightly summary score: 6.29, Thursday 6.94

• https://bugzilla.mozilla.org/show_bug.cgi?id=1509643 is quite visible in crash stats, but fixed by a WR pull request
• Mission Control Linux spike is due to https://bugzilla.mozilla.org/show_bug.cgi?id=1508096
• [wlach] note that buildhub still having problems (e.g. builds less than 24 hours old not showing up as I write this: https://mozilla-services.github.io/buildhub/?versions[0]=65.0a1), so nightly rates may still be slightly off. things improved from last week though.

Beta

firefox beta summary score: 2.15, Thursday 2.21

• Mission Control detected an increase in Mac content crashes, https://missioncontrol.telemetry.mozilla.org/#/beta/mac/content_crashes. Doesn't

seem to be a corresponding spike shown in Socorro

• • [wlach] not a lot of data on mac, looking at the data on an hourly level, not a big difference from previous betas: https://screenshots.firefox.com/a3HkvT4snAJzY4ES/data-missioncontrol.dev.mozaws.net (so probably a false alarm)

Release

firefox release summary score: 2.37, Thursday 2.43

• crash during auto-update with firefox monitor: https://bugzilla.mozilla.org/show_bug.cgi?id=1509352 - 35% of browser crashes in 63.0.1
• trend micro releasing a fix for the startup crashes in https://bugzilla.mozilla.org/show_bug.cgi?id=1490637 today - 1.3% of browser crashes

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: 25.45, Thursday 25.73

• https://bugzilla.mozilla.org/show_bug.cgi?id=1508740 is #4 overall, still waiting on a ni

• Beta

fennec beta summary score: 28.27, Thursday 29.09

• #4 overall https://bugzilla.mozilla.org/show_bug.cgi?id=1464902 seems stalled, no clues and affects Firefox as well

• Nightly

fennec nightly summary score: 45.72, Thursday 48.24

• Top browser crash https://bugzilla.mozilla.org/show_bug.cgi?id=1507513 is resolved fixed
• https://bugzilla.mozilla.org/show_bug.cgi?id=1499618 is now the overall #2 top crash
• #7 top crash https://bugzilla.mozilla.org/show_bug.cgi?id=1505061 discussed during triage, will try to reproduce on one of the sites noted in the bug
