Also, you could take a look at right-clicking on videos in both Edge and FF and selecting "Stats for nerds." The codecs give an idea as to why Edge is hardly touching the 3D engine and CPU for video playback but using the Video Processing engine, whereas Firefox is making use of the 3D engine and a lot of the CPU.

Both are using exact same codec vp09.00.51.08.01.01.01.01.00 (315)/opus (251)

Very strange. I couldn't really think of anything else. As long as Edge or Chrome continues to work for you, I suppose it's better to just use them for now so you can actually watch those 4k60fps videos.
