According to Crash Stats this doesn't seem O-specific, though.

Comment 2

[Jan Henning [:JanH]]

Unless there was a recent jump in frequency (which there wasn't, as far as I can tell from Crash Stats [1]), there's no point in looking for a regression window: Looking at the crashes in the last 6 months, we still have a number of users using older versions and there are crash reports going back all the way to Firefox 26 [2], which is when the Home Pager was apparently introduced.

[Mira Lobontiu (Android QA)]

Taking into consideration Comment 2, I will remove the regressionwindow-wanted flag.

Thanks!

Closing because no crashes reported for 12 weeks.
