I've fixed the immediate problem in SVN now (rev. 43).
You should be able to access the server now.  However, it's InteProxy that 
asks for the password now, not Firefox.  It would be better to let the 
browser handle the user interaction in this case.

It's not easy to fix it, though.  The problem is that InteProxy uses urllib2 
to connect to the remote hosts and urllib2 is a bit too intelligent for our 
purposes in that it wants to handle the authentication itself.  It would be 
possible to override that but I suspect that similar problems will crop up in 
the future too.  Some of the problems we had in the past (e.g. issue #271) 
were aleady at least partly due to the use of urllib2.

This automatic handling of authentication was one of the reasons to use 
urllib2 originally, but back then InteProxy wasn't trying to be a regular 
http proxy for use with normal browsers and other programs which can handle 
such things themselves.

I suggest we ditch urllib2 and implement what little we actually need from the 
http protocol ourselves, or at least use httplib instead.
