Found a couple on github:
I've never used any of them.
@waglo Yes, especially older scientific data is often on FTP servers and we link from homepages to such FTP servers for people who want the data.
Even if in the end you use FTP to download all the data, it is useful when these links are not broken and people can get a peek.
Newer data is on real data repositories, but not too long ago FTP was the standard.
@VictorVenema Use something other than Firefox, then. It's not the sites that are in the wrong, it's the browser, so change the browser, not the sites. There must be some good GUI and TUI clients out there.
@VictorVenema If "FTP Death" occurs, it will just spawn a new set of applications dedicated to supporting FTP, as developers using things like Firefox for FTP are inspired to write their own software for it.
Also, I know that Lynx and cURL supports FTP, and they seem quite dedicated to supporting older protocols. There's no need to panic, and not for a long, long while.
@StampedingLonghorn Already installed. But that does not fix the broken links to FTP servers with climate data.
