FireFox Problem

I’ve been having a problem with firefox for the last few days. Everytime i’m on Youtube and try clicking to go to another video i’m getting “Not responing” at the top of the browser for a few seconds and at other times a pop up from firefox keeps popping up to tell me to close the browser because of a fault.
Any ideas what the problem can be? it only seems to be happening on Youtube
