7 affected, 11 fix-option sec-crit/high bugs

• Functionality

Stability

• Today for Desktop only we are reporting with the new MCv2 dashboard. See https://metrics.mozilla.com/public/sguha/mc2/faq.html

for explanation of crash incidence and crash rates.

• • Note: Adoption matters in this dashboard - less than 10% adoption means you should take results with a grain of salt

Nightly

Crash Rate overall 1.88 Crash Incidence overall 5.53% Mission Control v1 rate: 5.45

• Added a ni on https://bugzilla.mozilla.org/show_bug.cgi?id=1587794. Spike seems to have tapered a bit
• WR #4 top crash has a fix and is awaiting checkin - https://bugzilla.mozilla.org/show_bug.cgi?id=1585801
• #2 DOM Service Workers crash https://bugzilla.mozilla.org/show_bug.cgi?id=1578919 is resolved fixed
• Top macOS crash https://bugzilla.mozilla.org/show_bug.cgi?id=1587351 is also resolved fixed

Beta

Crash Rate overall 2.01 Crash Incidence overall 1.16% Mission Control v1 rate: 2.89

• nothing major to report for 70.0b14
  • new mission control shows 40% crash jump from b13 to b14 in mac browser crash rate, is there anything we can find to explain this?
    • aha, i hadn't notice it was mac only. Then, we don't have much data to go on so i'm not worried +1

Release

Crash Rate overall 2.00 Crash Incidence overall 0.90% Mission Control v1 rate: 1.96

• Top crashes are either OOM or JS: https://crash-stats.mozilla.org/topcrashers/?product=Firefox&version=69.0.3&process_type=any
• recent OOM spike (tentatively tied to facebook) is under investigation in https://bugzilla.mozilla.org/show_bug.cgi?id=1584266

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.

Nightly

fennec nightly summary score: 72.44, Thursday 72.09

• https://bugzilla.mozilla.org/show_bug.cgi?id=1527243 is still the top crash on nightly. Appears stalled since we cannot reproduce it

Beta

fennec beta summary score: 51.96, Thursday 53.24

• Nothing specific to call out for Fennec beta today

Release

fennec release summary score: 18.23, Thursday 18.56

• Added some comments to https://bugzilla.mozilla.org/show_bug.cgi?id=1587166
