I guess you mean you downloaded Firefox instead of updating Explorer.
Either one, it doesn't matter, here is more stuff to check....
Make sure your Browser cache is not showing you an old version of the page. There is a way to make it get a fresh update every visit but many older browsers just display a page they have stored on your hard drive. If you tell me which Browser you have I will give youu some instructions.
Do you have a 800x600 monitor? If you don't know how to find out tell me what version of Windows you have an I will give instructions.
I will call you and talk you through it if it gets to be much more to it than this.
