No no no. Internet Explorer is NOT the problem.
Stop being halfbrained fancigarettes.
It's not the browser you use, it's the one that's using it.
Huge problem is determined by looking below the title bar.
I see 3 toolbars that you definently do not need, and there's probably more hidden away. Uninstall those piles of stuff, uninstall whatever mywebsearch bullstuff you have on there, and never touch Internet Explorer ever again and hope to god you don't find a way to break Firefox.
