So from the user agent, it looks like a Mozilla Browser (there was never a Netscape 5, if i can trust

And the file dialog looks like the one in GNOME.
edit: compare this to the iliad browsers user agent:
Mozilla/5.0 (Windows; U; Windows NT 5.0; de-AT; rv:1.7) Gecko/20040608
this is from Mozilla 1.7 on Windows 2000. Very similar, isn't it?
another edit: looks like you are alpha-testing Firefox 1.6.

the last edit (hopefully):
i was totally mistaken. Seems like they are really running a version of Firefox 2.0 there. Just downloaded the last beta, here's the user-agent of it:
Mozilla/5.0 (X11; U; Linux i686; de; rv:1.8.1b1) Gecko/20060710 Firefox/2.0b1
