@Kidplayer_666 On Firefox/LibreWolf look at page: about:support -> Graphics -> Compositing. If it says “WebRender (Software)” it is not using HW accel. If it is using HW accel it will just say “WebRender”.
on Chromium/Chrome/Vivaldi etc. look at page: chrome://gpu/. You want to see “Hardware accelerated” and not “Software only. Hardware acceleration disabled”.

@Kidplayer_666 @opt9 What platform are you on? Chromium supports hardware accelerated video on Raspberry Pi’s, so less CPU load, while #Firefox (and derivatives like #LibreWolf) is about to with the upcoming 116 release. Currently I use LibreWolf on my Pi4 except for video watching and then I go back to Chromium. Once version 116 comes out I won’t need to switch.
HW accel should be automatic on targets that support it (x86, AMD, Apple). I run on a #RaspberryPi4 target which is #Arm64 and doesn’t support it “yet”. The fix has been checked into git so next release will fix it on Firefox and LibreWolf. In your case though, if Firefox is working then LibreWolf also should.
I’d ask @librewolf if they have any ideas why it wouldn’t work. The Google turned up this: https://www.reddit.com/r/LibreWolf/comments/11isnra/how_to_enable_hardware_acceleration/
