Stability

• https://bugzilla.mozilla.org/show_bug.cgi?id=1528996#c11 explains the MC rate jumps for nightly and now beta

Nightly

firefox nightly summary score: 5.51

• https://bugzilla.mozilla.org/show_bug.cgi?id=1533539 is still a top crash, averaging 20-30 crashes per build
• A/V Playback crash https://bugzilla.mozilla.org/show_bug.cgi?id=1537554 very visible on nightly as well as beta

Beta

firefox beta summary score: 12.35

• Service workers crash https://bugzilla.mozilla.org/show_bug.cgi?id=1535699 is quite high in beta

Release

firefox release summary score: 4.36

• DOM Quota crash https://bugzilla.mozilla.org/show_bug.cgi?id=1487194 is still quite visible across all branches. One of the comments mention patches, but it doesn't reference which bug
  • If it is https://bugzilla.mozilla.org/show_bug.cgi?id=1530284 there is no activity since 17 days ago
• Cross Platform crash https://bugzilla.mozilla.org/show_bug.cgi?id=1535064 is #6 overall, and one of the top crashes on Mac 66
• Reproducible Win 10 tab crashes is #7 - https://bugzilla.mozilla.org/show_bug.cgi?id=1521370, fixed in 67
  • this will be fixed in a likely 66.0.2 next week

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: 19.88

• • Top crash https://bugzilla.mozilla.org/show_bug.cgi?id=1535766 is now resolved fixed and going into beta

• Beta

fennec beta summary score: 849.16

• • https://bugzilla.mozilla.org/show_bug.cgi?id=1493611 is also at the top of crash stats for beta 3
  • #2 top crash https://bugzilla.mozilla.org/show_bug.cgi?id=1532456 seems stalled and is marked as a P3
  • [wlach] missioncontrol graph is rather concerning: https://data-missioncontrol.dev.mozaws.net/#/beta/android/main_crashes?aggregateLength=1&timeInterval=1209600&relative=0&percentile=99&normalized=0&disabledVersions=&versionGrouping=version (crashes are quite high given the low amount of usage, sustained over the last few days)
    • marcia will file a bug following the meeting

• Nightly

fennec nightly summary score: 144.61

• • Top crash https://bugzilla.mozilla.org/show_bug.cgi?id=1493611 just had a fix pushed
  • Low volume Core | Editor bug https://bugzilla.mozilla.org/show_bug.cgi?id=1536852
  • [wlach] m-c rate looks high but this seems the usual behaviour looking at the graph: https://data-missioncontrol.dev.mozaws.net/#/nightly/android/main_crashes?aggregateLength=1&timeInterval=1209600&relative=0&percentile=99&normalized=0&disabledVersions=&versionGrouping=version
