Mobile Stability


  • 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.


  • we had an ANR spike earlier this week



  • feature prioritization is in progress, so far so good

Aurora / Dev Edition


  • Windows Default Browser Agent will be ready in the next Nightly, still targeting March 18, awaiting approval from leadership
