I absolutely love it, thank you!!! Just remembering my speed setting would be enough and here I can control it with shortcuts, najssssss... Where's the "donate" button?

Работает скорость клавишами регулируется

Please support firefox preview :D

Most comprehensive version of this tool I've found. Great stuff.

Very good extension

It does what exactly it says: accelerating videos. Very good app.

Very straightforward speed controller. Helps me process student videos for projects at a higher rate of speed to make grading processes smoother. Thank you for this add on.

so useful, even can speed up audio (BBC Sounds) and works well with preset speeds

very happy this was ported from Chrome :)

This is a much needed and appropriate port from the best Chrome extension for video controlling. Works great, unfortunately it doesn't seem real that it would work starting from Firefox 48 as described. As I'm using Waterfox (FX 52 ESR equivalent), v0.5.1 is the only one really doing the job (attachShadow problems).
