Works very well and stable. First I used it to watch youtube videos at speeds higher then 2x. But now I also use it on many other sites and this extension became one of my "must haves".

Life changing good extension, the keyboard controls are great ('R' even allows to toggle to last played speed!). I had to restart firefox for it to work (ubuntu)

plz. add swipe control

Useful enough to be essential.

Very very good!

Very helpful add-on. It has only 1 bug that is It reset playback speed to 1X when page get refreshed or new video is selected to watch on the same Tab. Please fix it.
Overall BEST add-on.

Fonctionne comme il faut :)

Amazing, if I ever meet the devs I'll kiss them all on the forehead. Thank u so much
