FireFTP is open source software with a touch: it is also Charityware. If you choose to donate, read what the author of the extension has to say;

“Where does this money go? Half of all proceeds go towards helping various orphanages in Sarajevo, Bosnia & Herzegovina and in Vukovar, Croatia. I spend my summers with these little guys and they are seriously the best kids in the world. [...] Your donation goes towards making this world that these little brothers and sisters of mine are living in a better place. The other half of the donation goes to helping put bread on my table for me and my family and funding the future development of FireFTP.”

FireFTP is a quick and easy solution for those in need of an occasional FTP transfer and do not wish to blur up their list of programs with yet another rarely used aplication.
