Title says it all. Got the message of three remaining videos and then it locked.

I am using FireFox

Edit: Apparently, it was caused by me being logged into YouTube. But I would really like to be. Because that's where all my subscriptions are. If anyone knows of a way to have it both ways, please let me know.

Edit' : It was my Ghostery extension that was causing ruckus. I don't really like the idea of having to switch it off but at least it's nice to know the cause. Anyway, everything is working now. Even when I am logged in ^^
