When I open YouTube in Firefox when I am not signed in it works well. But when I am signed in when I try to watch a YouTube video it stops responding. I upgraded Firefox to 40.0.3, didn't work. I am running Windows 10.

I removed the individual cookie for YouTube but I have the same problem. I think I need a more detailed way on how to fix this
