All metrics look great!

  • Stability
  • Performance
  • Security

7 affected, 11 fix-option sec-crit/high bugs

  • # of open carryover regressions is still a bit high, ~25
    • This doesn't match my query, which shows 5 carryover bugs on 70. we should compare queries

Off-train releases

Current Shield studies:


for explanation of crash incidence and crash rates.

    • Note: Adoption matters in this dashboard - less than 10% adoption means you should take results with a grain of salt


Crash Rate overall 1.88 Crash Incidence overall 5.53% Mission Control v1 rate: 5.45


Crash Rate overall 2.01 Crash Incidence overall 1.16% Mission Control v1 rate: 2.89

  • nothing major to report for 70.0b14
    • new mission control shows 40% crash jump from b13 to b14 in mac browser crash rate, is there anything we can find to explain this?
      • aha, i hadn't notice it was mac only. Then, we don't have much data to go on so i'm not worried +1


Crash Rate overall 2.00 Crash Incidence overall 0.90% Mission Control v1 rate: 1.96


  • 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.
