I was somewhat more surprised to find use the URL:

ftp://someone:password @
 ftp .
 com/whatever/file

in netscape (at least 2.0 & 2.01) to retrieve a file.  The obvious
flaws with ftp password sniffing aside, netscape caches the URL in
plaintext.  In fact on my 32 bit windows version there's even the nice
little pull down box for recently used URL's.  All the night janitor
would have to do is pull down a recently used URL on someone's PC to
grab a password.  As far as I can tell there is not an easy way to
clear this box.  I haven't tried bookmarking on the recent version, but
it's probably just as bad.

I can imagine the possibilities in a University Computer Lab where some
student wants to ftp to their server from Netscape for some reason.

P.S.  At least Netscape stopped printing in on printouts in recent
versions.
