for firefox there is the addon Video Assistant that will auto play video from embedded & video sites in your chosen system video player. I find mpv works well for this because it has a very quick load time and a basic, minimal window that i then put on-top and have the video playing in the corner of my screen while i do other things.
And maybe go to about:config in firefox and disable mediasource with
media.mediasource.enabled=false
mediasource (MSE) is a modern WebAPI used by vimeo, youtube and some popular video websites to throtle streams (or download stream chunks at different moments and resolutions/quality depending on instant network bandwith available) from javascript in the client. Besides cross-origin problems (I guess it's the implementation fault) and possible LibreJS issues, Video Asssitant can't get an URL to give the video player if you have mediasource enabled and go to websites that use mediasource. At least for now those sites degrade to http(s) urls if mediasource is unavailable in the browser.
Well, I just tried some examples, maybe it's not completely true generally, but it seems to work like this in my short experience.
