"ftp" program is using native FTP protocol directly to the remote site.
OK.

browser is sending proxy ftp:// URLs and letting Squid perform native
FTP protocol directly to the remote site. OK.

FileZilla wraps individual FTP connection data in HTTP CONNECT
*message* and sends to the HTTP proxy to make a *TCP* connection to the
FTP server. OK in theory.
however, each FTP channel requires a new request and data connections
use random ports.... Breakage whenever the CONNECT is limited to
specific ports (just about everywhere).
To proxy FTP well you need an FTP proxy. + FTP was designed not to be
proxied. There is one called frox proxy which handles FTP with some
tricks.
