It works well, but configuring shortcut keys seem a little buggy

Perfect, just what I needed since I like to listen to videos on a faster speed in the background as I do things.

Awesome. Thank you. Works great.

Just tried it now it is working great based on 5 seconds of testing lol!!

Using keyboard shortcuts is convenient!

pls develop the add on for mozilla mobile

Very flexible! Customizable shortcuts are awesome!

easy to use and simple non-obtrusive design. you can customise the shortcuts and their key bindings, which is great. has run well on all the sites i've used it on so far.
