yeah, some pages are only designed for internet explore. cannot make compatibility with firefox 3.x/4.0 or google chrome 10.x.x.x, for example, zude.com, these kind of websites now are minorities, but they exist. so at least, you need 2 internet browser for all you need, an IE browser version upper than 7.0, and a firefox 4.0 or a google chrome 10.x for fast browse.

Hi cityminz, Thanks very much for your reply. I thought there might be an add-on or something for Firefox. Cheers Bazzalee

just like the democrats and republicans, somethings just don't work well together

That is an MS Office document as you can see by looking at the View > Page Source.
Only IE is able to display such a document properly.

I also had this problem with a page that had previously loaded fine on Firefox before, but then would not. I cleared the cache and closed the window. It then loaded just fine after that.
