Stability

Nightly

Today Crash Rate overall 2.15 Crash Incidence overall 2.17%, Mission Control v1 rate 4.74 Tuesday Crash Rate overall 1.62 Crash Incidence overall 5.11%, Mission Control v1 rate 4.73

• mission control v2 crash incidence is calculated differently now (old nightly baseline was incorrect)
• since a change of the crash reporter 10 days ago only ~20% of windows crash reports are indexed and visible on crash-stats
  • willkg is working on a fix https://bugzilla.mozilla.org/show_bug.cgi?id=1603236 - afaik no old data should be lost; it just needs to be reprocessed

Beta

Today Crash Rate overall 1.86 Crash Incidence overall 1.15 %, Mission Control v1 rate 4.72 Tuesday Crash Rate overall 1.68 Crash Incidence overall 1.30%, Mission Control v1 rate 4.09

[72.0b5]

• Gfx Crash in [@ mozilla::gfx::RecordedEventDerived<T>::RecordToStream]: https://bugzilla.mozilla.org/show_bug.cgi?id=1600491 - 2.2% of tab crashes
• WebGL Crash in [@ gl::Program::getInfoLogLength]: https://bugzilla.mozilla.org/show_bug.cgi?id=1601703 - 0.8% of tab crashes

Release

Today Crash Rate overall 1.45 Crash Incidence overall 0.94%, Mission Control v1 rate 3.23 Tuesday Crash Rate overall 1.52 Crash Incidence overall 0.97%, Mission Control v1 rate 3.67

• Crash in [@ objc_addExceptionHandler | -[NSOpenGLLayer drawInOpenGLContext:pixelFormat:forLayerTime:displayTime:]]: https://bugzilla.mozilla.org/show_bug.cgi?id=1601985 - 7% of macos browser crashes

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.
