Its by no means impossible - there are programs like ftp-gw which do just
this. But squid doesn't....

Yes. FTP proxying for a browser is different from FTP proxying for a full
FTP client. It is part of the standards that a browser will just send
something like "GET ftp://ftp.ibm.com/ HTTP/1.0" to squid, and squid will
use its builtin FTP client to retrieve it from the remote FTP site.

If you need to proxy a full FTP client, then I suggest you look at something
like the TIS toolkit ftp-gw, and make sure you have a client that can use it
(not all graphical ones can, but command-line ones are generally okay).
