• https://bugzilla.mozilla.org/show_bug.cgi?id=1549718 can cause data loss when updating to 66.0.4 / 60.6.2, and is the reason we're back at 0% for now

• merge was tentatively moved from May 6 to May 8, TBC

• For both related and unrelated reasons, nightly updates were turned off for pretty much the whole weekend. That means 68 is not in the happy state it should be in its last week on nightly.

Current Shield studies: https://strategy-and-insights.mozilla.com/shield-studies/index.html

Release

firefox release summary score: 1.82, Thursday 1.83

[66.0.4]

• https://bugzilla.mozilla.org/show_bug.cgi?id=1525078 continues to be visible in both release and beta, but comments mention there is not much we can do about it

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: 16.29, Thursday 16.50

• • Nothing new in the top 20.

• Beta

fennec beta summary score: 50.27, Thursday 55.85

• • Mission Control rate is high, but latest betas don't seem to have explosive spikes
    • https://bugzilla.mozilla.org/show_bug.cgi?id=1521158 is still around in b16 so that may be a contributing factor
    • Still early for b17 https://crash-stats.mozilla.com/topcrashers/?product=FennecAndroid&version=67.0b17&process_type=any

• Nightly

fennec nightly summary score: 126.02, Thursday 95.87
