incredibly good tool to change the speed of videos and even skip back and forth in videos where you normally don't have that option (some webinars for example)

So grateful for this extension! You have saved me HOURS of watching study videos. THANK YOU!!!

Firefox port of one of the most useful Chrome plugins.

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
