Release

firefox release summary score: 1.85, Thursday 1.87

• Nothing specific to call out. Rate looks very good overall

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.
