• stability data for release still looking mostly good - no unexpected major crashes & topcrasher lists dominated by issues on shutdown

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.
