Beta
firefox beta summary score: 2.74, Thursday 3.10
- 69.0b8 - the top 8 signatures are all Javascript related and have been around
Release
firefox release summary score: 2.34, Thursday 2.48
- spiking signatures in 68.0.1 compared to 67 cycle:
- shutdownhang | mozilla::ipc::GeckoChildProcessHost::WaitUntilConnected: https://bugzilla.mozilla.org/show_bug.cgi?id=1541344 - 4.6% of browser crashes
- AsyncShutdownTimeout | AddonManager: Waiting to start provider shutdown. | EnvironmentAddonBuilder: https://bugzilla.mozilla.org/show_bug.cgi?id=1513855 - 2% of browser crashes
- mozilla::dom::indexedDB::`anonymous namespace'::QuotaClient::ShutdownTimedOut: https://bugzilla.mozilla.org/show_bug.cgi?id=1541776 - 1.4% of 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.
Nightly

- https://bugzilla.mozilla.org/show_bug.cgi?id=1557661 is the top crash - trying to figure out why it is so high

- Nothing specific to call out for beta other than https://bugzilla.mozilla.org/show_bug.cgi?id=1461724
Release
fennec release summary score: 20.27, Thursday 85.65
- https://bugzilla.mozilla.org/show_bug.cgi?id=1532704 is pretty high, but because there are different issues under one signature, we may not be able to do anything about it
