deixou de funcionar no firefox.... já desisntalei e reinstalei tanto o firefox quanto a extensão, mas não voltou a funcionar

Essa extensão salva vidas e tempo.

OK

Dobrý

Fantastic addon, it saved me so much time over the years of using. I install it on all machines I use.

You can speed up slow talking videos, use same set of shortcuts to RW/FF for all videos, skip over commercials on many sites... Works like a charm.

Many thanks to developer.

I liked that it worked by keyboard but I dont want that icon on the video all the time. Also it disorts the sound too much by slowing or speeding it up (which is prolly a yt thing because the same disortion happens when I use the yt speed settings). When I can use my software player with slow or fast vids and change the speed there than the sound is perfect.
