I just tried this in a current Firefox.  The site worksforme, if we're 
talking about the ZIP upload on the front page.

The code you mentioned is commented out in their JS, like so:

   /* KRC 6/19/2008 #8234

They still have various other silly checks (like requiring a filename 
that's at least 6 characters long without telling the user that's what 
they require), but that's not really relevant to this discussion.
