Firefox - video high CPU usage not working after wiki fix

Hey guys,
So lately I changed from Windows to Linux and I picked Arch Linux which is great
but I got a problem with high usage of CPU in Firefox on it.

I used solution from https://wiki.archlinux.org/title/Firefo … celeration, and it works great for example for YouTube, dropped from 50% to 10% while watching 4k, but my problem is outside YouTube,
for example for twitch the solution broke watching videos there, I can see an error: `Your browser is unable to play the video or audio. If this shit happens on all Twitch.tv channels, then your browser does not support H.264 or AAC`

Somebody could give me some help on that please?
