Nightly

firefox nightly summary score: 4.20, last week 4.19

• Nightly build from 7/27 had a lot of Windows ShutDown Kill crashes: https://crash-stats.mozilla.com/search/?build_id=20180727103347&release_channel=nightly&product=Firefox&platform=Windows&date=%3E%3D2018-07-26T00%3A00%3A00.000Z&date=%3C2018-07-29T20%3A26%3A26.000Z&_sort=-date&_facets=signature&_columns=date&_columns=signature&_columns=product&_columns=version&_columns=build_id&_columns=platform#facet-signature
  • This was a spike across all Win versions, not just Win 10.
• Latest Nightly crash triage - https://wiki.mozilla.org/NightlyCrashTriage/2018Q3
• Mission Control detected an increase in content crashes in Linux - see https://data-missioncontrol.dev.mozaws.net/#/nightly/linux/content_crashes.
  • It appears this might be related to tiling being enabled - see https://bugzilla.mozilla.org/show_bug.cgi?id=1477444 for example

Beta

firefox beta summary score: 2.94, last week 3.04

[philipp]

• AsyncShutdownTimeout | profile-change-teardown | Extension shutdown: https://bugzilla.mozilla.org/show_bug.cgi?id=1464938 - 12.3% of browser crashes
  • patch not applying to beta, needs some rework (some of the crashes are also continuing after the patch landed on nightly)

Release

firefox release summary score: 2.34, last week 2.41

• Increase in content crashes with newly released intel gpu driver over the past weeks: https://bugzilla.mozilla.org/show_bug.cgi?id=1479795

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: 28.40, last week 28.52

• • Some new comments in Top crash https://bugzilla.mozilla.org/show_bug.cgi?id=1468541#c47 suggest there is outreach going on.

Andrew Sutherland also filed a bug based on his suspicions: https://bugzilla.mozilla.org/show_bug.cgi?id=1478707

• Beta

fennec beta summary score: 32.30, last week 32.71

• • Filed #12 top crash https://bugzilla.mozilla.org/show_bug.cgi?id=1479783. Affects API #19 only
    • There is also another signature that affects API 19 only -> https://crash-stats.mozilla.com/signature/?product=FennecAndroid&version=62.0b11&signature=libstdc%2B%2B.so%400x2fcf&date=%3E%3D2018-07-24T08%3A16%3A54.000Z&date=%3C2018-07-31T08%3A16%3A54.000Z&_columns=date&_columns=product&_columns=version&_columns=build_id&_columns=platform&_columns=reason&_columns=address&_columns=install_time&_sort=-date&page=1#summary

• Nightly

fennec nightly summary score: 60.23, last week 60.48

• • Top crash https://bugzilla.mozilla.org/show_bug.cgi?id=1477041 is now resolved fixed
  • #3 top browser crash https://bugzilla.mozilla.org/show_bug.cgi?id=1476751, may need to re-triaged if we think it would increase when it hits release.
  • Google Play store data does show ANR/Crash rate declining after a large spike on 7-19
  • Note: Rate for nightly doesn't show much of a downward trend, even though the crashes have decreased. Pascal asked Will if he could have the rate calculated differently so that we could account for this difference in nightly.
