When using firefox it is running choppy.... The spinning circle clicks if you understand what I mean. It doesn't run in a smooth circle. When I run in safe mode, firefox runs fine. I've tried disabling all my plug ins and it doesn't change it, still runs the same. I have a couple of lap tops and it's only doing it on this one. I can run other browsers fine, it's just firefox. I don't understand and don't know how to fix this. Even when I try to watch something using firefox, the sound is fine but the picture runs one segment at a time. Sorry - trying to explain.
