You mentioned the FTP server is back on a private IP.  If I recall how
this works correctly, the server is trying passive FTP and redirecting the
data flow to a separate, higher port.  Login works normally, which is why
you get the dialog for username/password, but the equivalent of a 'ls' is
what Firefox is doing and why it never loads the page.  The directory
listing data is what goes out over the data connection that the FTP server
is trying to express on that higher port.  That higher port is probably
blocked.

Whatever device is handling the gateway for your private network and doing
the port map back to the original system needs to be set to handle the
random higher port assignment - I don't recall what you wrote is being
used, but look up passive vs. active FTP and there should be something
documented.
