Correct. Squid only talks HTTP. This should also answer your next
question.

You run into trouble here because of the way browsers handle FTP. If they
are not using a proxy, they make an FTP connection to the FTP server. No
HTTP anywhere. To handle these clients squid would have to behave like an
FTP server. It isn't one. The second type of client is configured to use
an HTTP proxy. In this case the browser talks HTTP to the proxy but the
proxy talks FTP to the server. Same problem. Squid speaks HTTP, not FTP to
its clients.

Yes, squid is an HTTP proxy.
