[Bug 1870161] Re: Tabs in Firefox 74.0 crash on some websites: [GFX1-]: DrawTargetCairo::Snapshot with bad surface

[Ary Moonc]

I have reviewed my "about:support" contents and found preference "gfx.canvas.azure.backends" modified to "cairo" (from default "skia").
Toggling this entry between those two values (and restarting the browser) seems to fix/reproduce the issue 100% of the time.

I also had "gfx.content.azure.backends" set alike, but changing this
does not seem to have any negative effect.

So with both set to "skia" the issue seems solved for me.
