• Flash
  • There is still a top generic crash from Flash

B2G

• Some B2G data but not much that's actionable yet
• Only the Mac data is useful.
• Kairo/Naoki on point to monitor this effort.
• Meta tracking bug 761905

Mobile

• 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
