Very useful for any video and audio file reading.

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.
