CrashStats 2012-09-11.png

  • 45% of all our crashes on Fx15 mobile are startup related.
    • Waiting for 15.0.1 release to see if the startup crashes might calm down.
  • Wishlist fix:
    • bug 756140 - even though this is with Cynogenmod, the number of crashes for this is huge (6240 crashes in 3 days) versus the next one down which is 1,576 crashes in 3 days. It's the biggest crash in 15/16
