Stability Wins

• bug 863288 – java.lang.OutOfMemoryError: at android.graphics.BitmapFactory.nativeDecodeByteArray(Native Method) at org.mozilla.gecko.AboutHomeContent/TopSitesView.getThumbnailsFromCursor(TopSitesView.java)

Stability

• Something regressed “EMPTY dump” crashes significantly on Nightly, see bug 866526 – Ted saw those and IIRC says he saw Firefox hanging somewhat, then probably going OOM and crashing with those reports. If anyone has a clue what checkin on Friday (April 26) could have caused that, please comment in the bug.

• Mobile Nightly Crash rate has gone back down. Great job Mobile Dev team!
