Very good, works as advertised. It's just that even with a modern 6-core 4.5Ghz CPU and 32GB of RAM, the sound quality in speed-up is really bad (much worse than Enounce Myspeed or many Chrome extensions doing video speed up).

If the author would improve the sound quality (give a selection for low-cpu-impact/bad quality and higher-cpu-demand/super-quality audio algo), then it would be perfect 5 stars.

Luv it

Best add-on ever. Pls make a safari version.

I use this all the time, saves me time...lots!
Controls work well and remain subtle and unobtrusive during video playback.
The "1.00" is easy to tune out, even on Netflix.
Super job!

used to work flawlessly on firefox for android up until a recent update was released, now everytime you load up a video the controls stay onscreen for 5 seconds and then disappear. the only way to get them to show up again is to pause and unpause the video.

Must have

Fantastic

I love it but it doesn't show Sometimes

nice

Très pratique pour accélérer les MOOC

it's an amazing, useful and easy to use extension.

Simply the best!

Great add on.

At last a port of Video Speed Controller for Firefox, thank you! Being able to adjust the speed with shortcuts is essential to me. It's like being able to read a text at the speed I want. Thanks again.

Exactly what I wanted!
