Beta

firefox beta summary score: 2.25, Thursday 2.30

[63.0b14]

• browser process crash pattern looks very good - 45% of all reports are crashes on shutdown
• content crashes:
  • fix for crash crash landing in b14 has caused sec sensitive issues & might need to be backed out again: https://bugzilla.mozilla.org/show_bug.cgi?id=1498784 (crash attempted to fix was ~2% of content crashes)
  • new OOM signature in 63; unactionable at the moment: https://bugzilla.mozilla.org/show_bug.cgi?id=1472062 - 7.8% of content crashes
  • third-party induced crashes from quickheal security: https://bugzilla.mozilla.org/show_bug.cgi?id=1489041 - 2.8% of content crashes

Release

firefox release summary score: 2.23, Thursday 2.28

[62.0.3]

• two signatures with potential sec impact spiking up in the past days - apparently triggered by server-side changes:
  • https://bugzilla.mozilla.org/show_bug.cgi?id=1499020 potentially related to recaptcha
  • https://bugzilla.mozilla.org/show_bug.cgi?id=1499198 potentially related to facebook browser game

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: 19.79, Thursday 19.68

• • #4 top crash https://bugzilla.mozilla.org/show_bug.cgi?id=1497134, which was reported as a spike in 62.0.3, also seems to affect 63 and 64
  • Filed https://bugzilla.mozilla.org/show_bug.cgi?id=1499415, since the signature didn't have a recent bug.

• Beta

fennec beta summary score: 33.00, Thursday 33.20

• • Top crashes continue to be https://bugzilla.mozilla.org/show_bug.cgi?id=1497526 (likely signature change) and longstanding crash https://bugzilla.mozilla.org/show_bug.cgi?id=760394
  • Nothing new in the top 10 other than a few single installation crashes.

• Nightly

fennec nightly summary score: 67.85, Thursday 72.05

• • Nothing specific to all out - rate looks good
