tls13-compat system add-on pushed to release on tuesday updated websense detection getting ready for 47.0.2 - 51.0.1




awsy rate: 4.39 (browser 1.07, content 3.32) telemetry from sunday (m+c-s): 1.79 (was 2.24 the week before, 2.95 at this point last cycle)


  • Crash rate down slightly from Tuesday's meeting
  • and F1398665248_____________________________ are top 2 browser crashes.
    • that flash crash signature also spiked up on older beta builds for one day - probably some external website change triggered that


awsy rate: 0.88 (browser 0.68, content 0.20) telemetry from sunday (m+c-s): 3.21 (was 3.22 the week before, 3.02 at this point last cycle)

[philipp] 52.0 rc1 nothing unexpected - crash fixes going into this build all seem to have worked:


awsy rate: 0.81 (browser 0.54, content 0.27) telemetry from sunday (m+c-s): 2.42 (was 2.44 the week before, 2.71 at this point last cycle)



awsy rate: 15.04 (browser 1.93, content 13.11) telemetry from sunday (m+c-s): 7.88 (was 15.17 the week before, 6.04 at this point last cycle)



Release awsy rate: 1.11 Beta awsy rate: 1.98


  • after a closer look at the high volume media-playback related crashes on beta it wasn't conclusive that this is really regression in 52, or if they are just generally rising on all channels
