@eastcoastweb There is always the good old command-line tool that is simply called "ftp" (netkit-ftp). Otherwise check the Category/Network-hookup/ftp category in the Free Software Directory: https://directory.fsf.org/wiki/Category/Network-hookup/ftp
@eastcoastweb OK let me try again 🙂
The default file manager in GNOME, called nautilus, can be used to access FTP servers. In the panel to the left in nautilus you choose "Other Locations", then you have "Connect to Server" at the bottom, enter e.g. "ftp://ftp.vim.org/" there. Maybe not as smooth as FileZilla but it seems to work.
@eliasr Thank you, I did not know that. I will check it out. :)
