After the recent bunch of windows updates i started noticing youtube loading much slower and other websites acting strange. Just now i tried to look at a link https://steamusercontent-a.akamaihd.net/ugc/47948470127416586/912CDEE3AD8B94CF3122B7338E89E24C9B6EC29D/

I get "No video support and MIME type found". I have uninstall/reinstalled, checked codex, disabled addons and downloaded Microsoft windows media pack, then restarted the computer.

Nothing seems to work. But i had to reinstall Firefox again because all my tabs would crash after the last reinstall.

I have a copy of the old YouTube HTML5 support page you can use as the first-level test of where video support is falling short:

https://www.jeffersonscher.com/sumo/html5-video.html

The expected result is: supported, probably, probably, supported, supported, supported

If yours doesn't match, which ones are a problem?

Helpful?

spp / sss I am not sure what to do with this information.

I also got errors when updating this reply. This stuff has only started happening recently and only noticed after a bunch of pc updates, am wondering if Firefox is being crushed by competition.
