Well, basically, you're kind screwed -- but there is some (not much, but some) hope.
If you've got KDE konqueror
sometimes will display IE-only web pages reasonably (you can tell konqueror
to emulate IE).
There are a bunch of add-ons for Firefox and Seamonkey that may do a good job (I don't know that, but maybe worth a shot -- if I hit one of those brain-dead sites I just navigate away right quick but I can see that there might be a need).
One other, really screwy but works, might be lynx
Lynx is a fully-featured World Wide Web (WWW) client for users running cursor-
addressable, character-cell display devices (e.g., vt100 terminals, vt100 emulators
running on Windows 95/NT or Macintoshes, or any other "curses-oriented" display).
It will display hypertext markup language (HTML) documents containing links to
files residing on the local system, as well as files residing on remote systems
running Gopher, HTTP, FTP, WAIS, and NNTP servers. Current versions of Lynx run on
Unix, VMS, Windows 95/NT, 386DOS and OS/2 EMX.
Lynx can be used to access information on the World Wide Web, or to build
information systems intended primarily for local access. For example, Lynx has
been used to build several Campus Wide Information Systems (CWIS). In addition,
Lynx can be used to build systems isolated within a single LAN.
Can't hurt, might work (and it's most likely on your box).
Hope this helps some.
