Useful extension and really customizable.

wonderful

Works with Canvas videos for college. Great because those don't have 2x speed or higher, so this fixes that issue. Thanks so much.

Extrem gutes Addon. Sehr einsteigerfreundlich und tolle Extras für Fortgeschrittene! Das Alles auch noch kostenfrei! Sehr zu empfehlen!

no sound is played at under 0.1 speed

3 stars only because of security issues!!!

The blacklist it has now is NOT the way to go! There should be a white list to enabled the extension only on the most common video sites.

Make your life easier

It works perfectly on porn video website lol

Good for increasing the speed of YouTube videos beyond YouTube's own limit of 2x.

Partly works on YouTube in Firefox Nightly for Android. Controller indicator works in desktop view. In mobile view, it doesn't respond to touch, disappears after a couple of seconds, and can't be brought back with a tap. Switching to desktop view is a reasonable workaround, but fix the mobile-view issues and you'll have a complete winner.

YouTube High Definition has to be disabled for the "force last speed" function to work. No worries about that, but just an observation for anyone puzzled by the function not working.
