Firefox 10.2 running extremely slow, especially compared to version 9 or Chrome or IE, why?

After reinstall Windows 7 I also upgraded to Firefox 10.2. FireFox seems to bog down and just doesn't want to connect to virtually any sight. I have set up both IE and Chrome to start like Firefox does and both are extremely fast. Is this a FireFox 10.2 problem that can be fixed? I didn't have this problem with version 9. What to re-install version 9 to test it, but don't know where to get it, can anyone help?

Hi gardenguy42,

Have you looked at the Knowledge Base article Fix Firefox using too much memory or CPU resources or Fix Firefox using too much memory or CPU resources? There is a lot of great information in there.

Hopefully this helps!
