Ok, I'm testing it. Seems currently the addon works but freezes YouTube the first time I use it. A little window pops up with "I'm not interested" etc. When I close it, everything is ok. The window doesn't pop up with another videos hiden. Can you fix it?

EDIT: ok, the window stopped popping up but the addond also stopped working xD Have you considered wrting the addon from the scratch?

EDIT: it's very hard to say how it works currently. Currently it doesn't work with playlists, but works with single videos, however I need to click 2 times sometimes.

EDIT3: I must give 1 star. Currently it sometimes works with bugs I described, sometimes doesn't work at all.
