• Crash in [@ mozilla::ipc::PrincipalInfoToPrincipal] increasing up to a few hundred daily reports again: https://bugzilla.mozilla.org/show_bug.cgi?id=1582647
  • looks like it's triggered by a third-party website change
• Some ongoing discussion in https://bugzilla.mozilla.org/show_bug.cgi?id=1581121 about crashes with third-party distro built versions (30% of linux browser crashes)

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.
