Crappy site. I have this plugin installed, which fakes user-agent-- it helps in many cases. this time it didn't help . I opened it up with IE and saw nothing but Perl and Javascript, and IMHO there should be no trouble with these in any browser [unless of course the scripts are configured to deny other browsers]. I toyed around with Proxomitron to filter out the part which determines OS and browser, but after the filtering it showed up incorrectly because of it. IMHO, it is possible to view it in other browsers with some fiddling; however I see no reason to toy more with this crap.

also this site demands your real data and doesn't have a privacy policy. i'm perfectly happy not being able to login there.
