Great Time Saver!
You can also do the same thing using Java Console, but its very simple to use.
Mostly you need to modify the shortcuts according to your convenience.
BIG THANKS to the Developer :)

Please, update the version to 0.5.8 as in chrome. The most useful addon I've ever seen..

Great, even works on firefox built-in player, thank you ! Could you have it work on dailymotion too ? They changed their design recently, I suppose that's why the addon doesn't work as the last update was earlier.

Great, simple, well designed, practical, saved me hours !
