Holy crap this works well, it works on the training videos on a website I have to watch for work. Now I can watch the hour-long training video at four times speed, huge game changer. It is true I have to go to extensions and click on it and then in a tiny page type in the number and pick apply and then navigate back to the page. So it would be nice if somehow didn't have to do all that, but it works and that's the important thing.

simple yet great!

Needs option to save speed for all videos and all pages. Also needs to adjust the settings page to mobile layout.

Simple, compacta y fácil de usar. Es justo lo que estaba buscando..

working perfectly with all sites
