• https://bugzilla.mozilla.org/show_bug.cgi?id=1487194 is still the top crash. Hopefully will be addressed in 68 timeframe

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: 16.18, Thursday 16.27
