Comment #39 there is mine... I was trying to help de-bunk the FUD about active FTP. It's been two months since I posted that and nobody's said anything. There doesn't seem to be very much demand for active FTP.

Looks to be the 2nd oldest bug that's still open. It was opened over 4.5 years ago!

I didn't realize hijack only supported passive... I've never tried to FTP to it from Mozilla. And I doubt that's a strong enough reason to get any of the Moz developers to spend time working on it.
