Stability

Nightly

firefox nightly summary score: 3.60

• Nightly rate looks good for the most part
• #3 top crash https://bugzilla.mozilla.org/show_bug.cgi?id=1473507 looks to be fixed
• 6 new bugs filed in the latest Nightly crash triage - https://wiki.mozilla.org/NightlyCrashTriage/2018Q3

Beta

firefox beta summary score: 3.65

[philipp] 62.0b6

• AsyncShutdownTimeout | profile-change-teardown | Extension shutdown: https://bugzilla.mozilla.org/show_bug.cgi?id=1464938 - 10% of browser crashes
• Mac crash in mozAccessible parent: https://bugzilla.mozilla.org/show_bug.cgi?id=1471504 - 20% of osx browser crashes
• Content crash in nsTArray_Impl<T>::ClearAndRetainStorage | mozilla::dom::MessagePort::CloseInternal: https://bugzilla.mozilla.org/show_bug.cgi?id=1470306 - 1% of content crashes

Release

firefox release summary score: 3.06

[philipp] 61.0.1

• OSX 10.9 content crashes: https://bugzilla.mozilla.org/show_bug.cgi?id=1471892 - 27% of osx content crashes
  • disabling omtp altogether seems to be the workaround for this - the current normandy pref flip rollout in https://bugzilla.mozilla.org/show_bug.cgi?id=1472308 isn't enough to mitigate the crashes
• OOM | unknown | js::AutoEnterOOMUnsafeRegion::crash | js::gc::StoreBuffer::WholeCellBuffer::allocateCellSet: https://bugzilla.mozilla.org/show_bug.cgi?id=1473892 - 2.7% of content crashes
  • signature newly showing up in 61; needs investigation
• shutdownhang in mozilla::dom::quota::QuotaManager::ShutdownObserver::Observe: https://bugzilla.mozilla.org/show_bug.cgi?id=1411908 - 3.5% of browser crashes
  • received a patch in 61 but it's still a frequent crasher; unanswered ni in the bug
• Filed https://bugzilla.mozilla.org/show_bug.cgi?id=1474624 since it is the #13 top crash on release

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: 29.36

• jchen assigned to investigate top crash https://bugzilla.mozilla.org/show_bug.cgi?id=1468541. No comments in several days
• https://bugzilla.mozilla.org/show_bug.cgi?id=1470925 still very high volume as well

• Beta

fennec beta summary score: 36.22

• https://bugzilla.mozilla.org/show_bug.cgi?id=1451891 is the top volume browser crash
• Filed https://bugzilla.mozilla.org/show_bug.cgi?id=1474633. Looks to have something to do with First Run, but not sure.

• Nightly

fennec nightly summary score: 38.20

• https://bugzilla.mozilla.org/show_bug.cgi?id=1451891 continues to the overall top crasher and is also the top browser crash in the latest beta.

It appears from a recent comment that Sorina may be able to reproduce it.
