This might be asked before. Internet explorer 11 plays youtube videos without any lag or stuttering issue at all. but as I played the same video in FF, I immediately notice stutter. using FF ver64 on win8.1 64bit. Tried enble/disable HW acceleration, extensions, but no joy.

Is Mozilla aware of this?

YouTube prefers a codec that can put heavy stress on your CPU called VP9. You can hide Firefox's ability to handle VP9 so that YouTube gives you H.264/MP4 instead and see whether that resolves it. This extension will do the job:

Any difference?

The new Firefox 64.0.2 update may help with the Youtube stuttering.
