Okay, then which version of Firefox supports a single tab crashing without the whole browser crashing with me not having to enable e10s?
Because I have enough of Firefox Stable with just recommended settings completely hanging up or crashing every time it encounters flash or similar things.
Flash already runs in a different process, even without e10s enabled.
Dunno why your Firefox is crashing every time it encounters Flash or similar media, but I can assure you that's not a common experience. Maybe try enabling click-to-play?
I filed a bug report for that, too, and it discovered multiple gaping holes in the sandbox, which, luckily, only allowed null pointer dereferencing (so no RCE problems, but still DoS)
