    Perfect. Got an i5 6300hq, was having ~50% CPU usage while watching 1080p@60fps. With this i got 25-30% CPU usage. Thank you!

    This add-on fixed my problem with YouTube immediately, I have a high end PC and it was freezing itself at 2x 1080p60. Thank you guys!

    Installing this fixed hardware video decoding. Now Firefox uses much less CPU even when I watch 4K videos with VP9. Task manager shows HW video decoding works. It was zero before.

    Still seems to work, finally no more choppy and painfully slow and in low resulution loading YouTube videos in Firefox, and no need to use YouTube in Chrome as a "workaround".
