Not sure why but recently youtube has been eating my CPU alive even playing 720p, found this addon and now it doesn't touch my CPU even playing 1080p... Why is this addon's functionality not the default?

This makes Youtube playback so much smoother, Youtube doesn't buffer indefinitely when I attempt to seek anywhere now!

It really does what it says. Keep up the great work, buddy.

The best extension for weak computers that can not support video in 60fps!

Good app. Its working i am satisfied.

bien

I don't even use this addon for the h264 aspect, just the fact that it can block 60fps videos (forcing 30fps) to prevent stuttering. Good job

The developer had the good foresight to listen to Mozilla and update their add-on, before the final release of Firefox 57. As a result, it is completely compatible.

This add-on also makes browsing and streaming videos even faster.

Funciona perfeitamente!!!
