CrossFTP is a 2 pack of FTP goodness. As separated programs, they keep Firefox more stable and reliable for FTP tasks. It comes with an FTP client as well as a server application and only needs the latest version of JRE.

This one is very different to FireFTP because it can run as a standalone program. So, instead of opening up Firefox and going through the pull-down menus all the time, you can just visit your desktop for a quick double-click to FTP your heart away.

The default version is FREE, which provides full function general FTP tasks and local resource/archive browsing. The Pro version requires a license fee after a one month evaluation period, and includes multi-threading, secure transfers, and FXP file transfers.
