Very good addon fast and functional, would like an option to leave the button strip all buttons always visible

I had a bit of a difficult time leaning how this Add-On worked, but once I got the hang of it (and customized the controls to my liking), I LOVED it! It's so nice to be able to watch videos in 2x or even 3x speed almost anywhere!

useful

Genial

One of the best add-ons out there!
Controls speed of every motion picture, even GIFs !!! It's Crazy!!
You can set your own shortcuts, so I set the same as youtube. Now I can easily speed up up to 6x or even more on youtube ! What else could you ask from a speed controller?

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)
