Works on Facebook Video, Twitter, YouTube, Netflix, and many more services.
It app will help you optimize your video viewing by allowing you to make fast playback speed adjustments, as well as rewind the video to hear the last few second one more time.
We don't read at a constant speed, and we talk much slower than we read - there is no reason why we have to listen at a constant speed and at a (very) slow rate.
Also this extension lets you use hotkeys to adjust the speed of your videos as you enjoy your videos.
