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: 22.09

• • High crash rate due to https://bugzilla.mozilla.org/show_bug.cgi?id=1535766, we are throttled at the moment while investigation continues

• Beta

fennec beta summary score: 19.93

• • Not much to call out for beta yet

• Nightly

fennec nightly summary score: 230.80

• • Not sure why MC score is so high
