this crash signature is not new per se but it's starting to occur more regularly in firefox 74.0b. it's a content crash hitting only users on 32bit windows 10 so far, but there are no clear correlations or indications in the reports of what might have regressed it.

With version 78 of Thunderbird there is a significant increase in crash rate [1], versus Firefox which is flat [2]. So pferhaps related to hardware acceleration, which Thunderbird enabled in in version 78?
