If Internet Explorer and Safari don't work for a website,
try downloading Mozilla. I was able to use my Mac to get
onto the Gap website with it. Mozilla.com.
There's another browser, Firefox, you might try.
For Mac OS X users, Omniweb and Opera are also choices. Firefox and Mozilla don't follow the Mac UI guidelines. Camino is a browser using the Gecko engine that actually has a normal Mac OS X (Cocoa) interface. I don't even bother with IE for the Mac since it is a Carbon app and hasn't been updated in years. (I never use IE anywhere; it's an accident waiting to happen.)
Omniweb dates back to NeXTSTEP (I wish Apple had left more NeXT stuff in OS X) and works quite well.
Opera is now free and looks and feels the same on a whole bunch of operating systems. It feels native on everything but Mac OS X.

I use Solaris SPARC, SuSE 9.3 x86, Mac OS X, OpenServer, and Windows on a daily basis. My home machines are a Sun U-10, a Mac G4, and a Windows box. My work desktop machine is SuSe 9.3.
I kind of think my use of UNIX goes right along with my feelings about audio equipment. hehe
Oh, I had an HP 9000 at home for a while, but found HP UX (PHUX) to be horrible. It's only good if you have a lot of HP test equipment, although it does LVM nicely too.)
Yeah, this was OT.
