Desktop Stability

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.




  • Nightly feature testing and pre-merge Regression testing are in progress, to be completed by Thursday, July 23
  • FC due: tomorrow. Following features haven't landed/not ready for testing
    • (PI-645) Remote Settings & WDBA MVP
    • (PI-644) WebGL Remoting – blocker issue (Bug 1632249) still not properly patched
      • [overholt] I think we need a different bug here because that one is RESOLVED FIXED
