Firefox started to crash in some situations

[ilya-fedin]

I use firefox-beta-bin, since some of the updates hardware acceleration stopped to work. Since b8fb014, it stopped to work at all and was presenting a dialog to start in safe mode after multiple attempts to launch. If I disable hardware acceleration in settings, it launches in normal mode but crashes in some situations. I don't know what those situations share but it's 100% not random, it crashes again if I repeat the steps. One of such actions is attempt to open about:support.

Never mind, it was the environment.memoryAllocator.provider
