For me it does not work. I can access most FTP server, but I have one, really important, where FireFTP fails.

User name contains "@" character and I cannot change it. Maybe that's the reason. Maybe it's because I use Win 7 64bit... I don't know. Anyway, it does not work for me. I can't connect to this server at all.
