Release

firefox release summary score: 1.87, Tuesday 1.89

• Nothing specific to call out for today's meeting

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: 16.64, Tuesday 16.67

• • A few signatures appear to be rising
    • https://bugzilla.mozilla.org/show_bug.cgi?id=1492183
    • https://bugzilla.mozilla.org/show_bug.cgi?id=1508740, but not actionable at this time

• Beta

fennec beta summary score: 60.86, Tuesday 62.37

• • ARM64 is our top crash on beta - https://bugzilla.mozilla.org/show_bug.cgi?id=1521158. Also #3 overall on nightly
  • Core | Canvas WebGL crash https://bugzilla.mozilla.org/show_bug.cgi?id=1546397 is still undergoing investigation. More crashes than installs
  • https://bugzilla.mozilla.org/show_bug.cgi?id=1539465 seems to be rising a bit. This is thought to be an issue we have seen before.
    • Chris makes a comment (https://bugzilla.mozilla.org/show_bug.cgi?id=1539465#c12) that we would need to aggregate all the related signatures and then

present to Qualcomm. Do we have someone from mobile that can do this?

• • #6 overall crash https://bugzilla.mozilla.org/show_bug.cgi?id=1374570 is still stalled

• Nightly

fennec nightly summary score: 61.33, Tuesday 61.61
