Firefox 5.0 Back button

[metalmania31]

Hello all since updating to FF 5.0 I've noticed I had to press the back button like 3 times before it goes back. This happens on my personal desktop at home and my work laptop both are Win 7 64bit. But they have completely different apps so I'm pretty sure none of that is creating the issue. Any ideas?

The first step is always to try running Firefox in Safe Mode, to see if the problem goes away: Help, Restart with Add-ons Disabled. If problem fixed, restart, disable half of your extensions, restart, test, see if you can find an extension that is causing the problem.

Next: Standard diagnostic - Firefox - MozillaZine Knowledge Base

I think I found the culprit after some more Google research. It seems some flash ads on forums are causing the problem. I blocked them with no script and voila fixed. It was still a problem even if I allowed all on No Script. Only when I blocked did it work correctly.
