I've had this problem for a couple of years already. Not with other browsers and, with the Internet Download Manager extension, I'm usually able to download multimedia content in FF. (That's been my workaround.)
For example, when loading this humble URL ...
... if I have autoplay enabled, it'll crash right away ("Your tab just crashed"), without autoplay, it'll crash as soon as I hit play. No report gets created under about:crashes.
No difference if I create a new user profile and disable add-ons. Disabling hardware acceleration doesn't help either. I can't do without most of my settings and add-ons, so refreshing FF is not an option. I'd sooner try a new install (and then import my profile and reinstall add-ons), but that's laborious, not guaranteed to solve the problem, and I figure that there ought to be some way to diagnose a crash in such straightforward circumstances? Telling the JS debugger to pause on exceptions seems to be no help.
Twitter videos used to work, albeit without audio, so long as I didn't pause and then resume playback. Lately, after upgrading from FF 104 to 105 (or possibly through a change on Twitter's end), I get "the media could not be played."
