8K60fps YouTube playback on M4 Apple Silicon Mac - bad performance despite low utilization

Even though CPU and GPU utilization is very low during 8K60fps Youtube playback in the Firefox browser on my base M4 Mac mini, the struggles heavily to play this, drops tons of frames, and the video almost stops playing.

8K 30 fps is not problem, and since utilization is pretty low, that doesn't explain the poor performance.

So please optimize 8K60fps Youtube playback on all platforms in the safari browser, but especially on Apple SIlicon Macs.

Update:

Had a typo in my post, I of course meant "Please optimize 8K60fps YouTube playback on all platforms in the Firefox browser, not safari.

And I've now tested about a dozen browsers, and only Firefox has issues with 8K60fps out of all of them.
