1.	Solve : A plug-in problem once starting up YouTube?
Answer» Nothing much to say, basically this happens: I GO to youtube, EVERYTHING's okay, I press on a video, it opens up, starts really lagging, shows me this: http://imgur.com/w5zkKHB Then I press Stop Script and it continues to work properly, but almost every TIME I open a video I get a 30-40 second LAGG before that thing pops-up. So, any suggestions?What OS and browser are you using?
