This is a very good add-on for Firefox. Since i watch anime i find most of the site players pretty messed up but this player is simple and interference is easy to use.
But it would be more awesome if in future it has features like saturation, contrast and brightness increase decrease for these feature i had to stay to site's own player using HTML5 script with temper monkey. I will really appreciate if you can add these features.
Thanks for your work.
