Stability

Nightly

firefox nightly summary score: 11.02, Thurs 5.51

• Tracking shutdown kill spike in https://bugzilla.mozilla.org/show_bug.cgi?id=1538274. Waiting for a patch
• https://bugzilla.mozilla.org/show_bug.cgi?id=1538098 caused the spike in crash rates. Early returns look as if the bug is gone in the latest build
• Single install crash in zz_AsmCodeRange_End | KiUserExceptionDispatch generated 2500 crashes, also not helping the crash rate
• https://bugzilla.mozilla.org/show_bug.cgi?id=1537554 is the top content crasher on nightly and also very visible in beta

• https://bugzilla.mozilla.org/show_bug.cgi?id=1537554 very high in b3 and b4. Fix appears to be in the works

• DOM Quota crash https://bugzilla.mozilla.org/show_bug.cgi?id=1487194 is visible on release, as well as other branches

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.
