Stability

Nightly

firefox nightly summary score: 6.83, Tuesday 6.91

• https://bugzilla.mozilla.org/show_bug.cgi?id=1547654 appears high on nightly, but few installs. It seems to have spiked in 20190515213039 when

some Mac users updated to 10.14.5

• Nightly pretty quiet overall. A few single installation crashes

Beta

  • Don't see anything concerning so far. rc1 has fixed our prior content top crasher https://bugzilla.mozilla.org/show_bug.cgi?id=1535699 successfully

Release

firefox release summary score: 1.80, Tuesday 1.81

• https://bugzilla.mozilla.org/show_bug.cgi?id=1552099 filed to account for the spike in xh-cn locales

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: 16.16, Tuesday 16.18

• • Device specific crash https://bugzilla.mozilla.org/show_bug.cgi?id=1525290 is still high in release. Not seen in 67 but in 68
  • Otherwise not much to report on Fennec release

• Beta

fennec beta summary score: 46.62, Tuesday 47.02

• • Leftover JIT crash https://bugzilla.mozilla.org/show_bug.cgi?id=1550525 is still the top crash, waiting for developer to take a look
  • https://bugzilla.mozilla.org/show_bug.cgi?id=1545429 is rising in beta, but likely won't be addressed in the 67 timeframe

• Nightly

fennec nightly summary score: 119.30, Tuesday 120.89

• • https://bugzilla.mozilla.org/show_bug.cgi?id=1524868 is #4 overall on nightly. Reproducible
