Mobile Stability

Fennec

• 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.

User Advocacy / SUMO Report

• corruption during the update process - reinstall seems to address it: https://bugzilla.mozilla.org/show_bug.cgi?id=1628452
• browser in a non-functional state (pages not loading, etc like we had in 73 with compatibility mode); still debugging
  • https://support.mozilla.org/en-US/questions/1283949
  • https://support.mozilla.org/en-US/questions/1283900
  • https://support.mozilla.org/en-US/questions/1283904
• [roland] over a dozen complaints in SUMO about the megabar mostly about embiggening when opening new tab
  • for the post mortem: have an AMA about big pixel changes during beta? involve community in release notes? explainer videos or material that volunteers can link to when users ask "what were they thing thinking" questions?
