Awesome. Thank you. Works great.

This plugin is very nice ! You can accelerate an infinite speed if you want (x15 x20 x50... lol)

In the options you can change every shortcuts you want, even changing the default ones (like space bar to pause on another key). I used the w and s for the acceleration and a and d for the +10 or -10 sec, t for setting the speed at 1.25 (by default speed) and r to reset back to 1.0 very fast.

It add a little icon on the top left corner of the videos and you can adjust its transparency.

When you mouse over the options while watching a video, the options never disappear (hide). So with your mouse, when you search say a specific sentence a politician said during a conference, you can speed to 2.50x and slow down the speed very fast without any hassle.

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.

The addon stopped working entirely today without any reason. I have already tried re-installing, but it still does not work.
