The Bugbug bot thinks this bug should belong to the 'Core::Audio/Video: Playback' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Reporter, do you have a couple of crash reports of this? about:crashes should list them all with a date, hopefully you can find a number of them and paste a link here for one of us to have a look at? Attaching a copy of the raw data of about:support might also be useful to diagnose this issue.

Thanks!

not sure if this help any, and dont ask me why, but i encountered crashes, too. let me explain:

i like to use firefox multi container. before the v100 update, everything worked fine. i could open a twitch stream on 30 different multicontainer tabs at the same time without any problem. if this worked or not, was only dependant on my RAM.

after firefox v100 update, it is enough to open a twitch stream on only 15 mutticontainer tabs, for firefox to start to crash single tabs. then opening like 20 or more streams, causes firefox to completely crash.

dont ask me why i did that experiment, i dont know either lol. but fact is, there were no issues below v100. but since update to v100, this doesnt work anymore. it also gave me an error.. but i clicked it away.. if it appears again, i will screenshot it.

Piter, would you mind copy-pasting a number of those crashes here? You can find them in about:crashes (type this in the address bar), with the date at which it occured. We can then have a look and try to diagnose your issue. Thanks!
