We are currently seeing a crash rate over 5.5 crashes per 100 ADI. In previous betas this number is under 3 crashes per 100 ADI.
I spent some time looking at the 43 beta 8 [1] and the 44 beta 2 [2] data. It looks like there are a few things going on. First there is a greater volume of OOM crashes across the board. We discussed this in the mobile engineering meeting and snorp suggested disabling the tile size changes that were new in 44 [3] [4]. We would like to get the fix for bug 1235855 into beta 6. It is a pref change and trivial to revert if the change does not have the desired effect. The second issue that is skewing the crash data is that the number 2 crash is the ABI mismatch [5]. Running Firefox for Android for ARM devices on x86 or vice versa. We have some code changes in v45 to try to alert users that they need to use a different build. They are rudimentary but at least give some feedback other than crashing [6].
