Release

firefox release summary score: 5.37

• New crash https://bugzilla.mozilla.org/show_bug.cgi?id=1553380 appears to be CPU specific, started in RC2

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.

• • GPC shows a high ANR rate for Fennec release
  • Top crash https://bugzilla.mozilla.org/show_bug.cgi?id=1539465 - not much to go on at the moment
