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.

Thanks for the report. Can you upload if necessary and link some (if any) crashes in about:crashes, please?

Can you go to about:config and set the pref media.eme.mfcdm.origin-filter.enabled to 1, then see if it helps? Thanks!

about:crashes should have a button at the top saying something like "Submit All".
Some time after pressing that, the "Submit" buttons will change to "View" links that you can follow and copy.
