Desktop Stability

Nightly

mc2 crash rate: 1.80, crash incidence: 2.80%, mc1 summary score: 11.49 tuesday mc2 crash rate: 1.64, crash incidence: 2.20%, mc1 summary score: 16.11

• #1 overall top crash fixed by backout: https://bugzilla.mozilla.org/show_bug.cgi?id=1609665
• #3 still showing up high: https://bugzilla.mozilla.org/show_bug.cgi?id=1614259
  • Affects DevEdition 75.0b also
• #4 waiting on review: https://bugzilla.mozilla.org/show_bug.cgi?id=1605478
• Lots of shutdown crashes dominating content crash results, makes it hard to see much else

Beta

mc2 crash rate: 3.25, crash incidence: 1.59%, mc1 summary score: 6.70 tuesday mc2 crash rate: 2.04, crash incidence: 1.44%, mc1 summary score: 36.07

[75.0b2]

• tab crash in trunc | cubeb_backend::capi::capi_stream_init<T>: https://bugzilla.mozilla.org/show_bug.cgi?id=1621360 - 4.3% of content crashes
• tab crash in mozilla::JsepSessionImpl::CheckNegotiationNeeded: https://bugzilla.mozilla.org/show_bug.cgi?id=1621770 - 2% of content crashes

Release

mc2 crash rate: 1.13, crash incidence: 1.14%, mc1 summary score: 5.89 tuesday mc2 crash rate: 1.31, crash incidence: 1.06%, mc1 summary score: 14.86

[74.0]

• crash pattern is very sane and shouldn't stand in the way of full rollout - nothing particular to call out
• Crash in mozilla::VideoStreamFactory::CreateEncoderStreams somewhat increasing: https://bugzilla.mozilla.org/show_bug.cgi?id=1521169
  • independent of version - perhaps more people are using webrtc to communicate because of the covid19 situation

Mobile Stability

Fennec

• 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.
• MC rates look typical for Beta (36.83) and Release (14.07)

Fenix
