Are there security issues with FTP, or do people just not use it enough because HTTP supplants it? I haven't used FTP in a while to download files.

Plaintext passwords over the net. Also, it's somewhat painful for NAT because it opens up a second port that isn't a named one, the client sends that port number to the server, then the server opens a connection to the client.

That's for active FTP, which basically nobody uses anymore (since it's incompatible with most firewalls).

Most clients use the passive FTP extension, in which the server sends the client a host/port pair to connect to for the data connection. Still painful, but slightly less so.

I love discussions about browsers on Hacker News! They're amazing. Half the people ranting how some insanely complicated technical decision is going to ruin the world, the other half yelling at them that this is necessary, others ranting about how the vendor is evil for some reason, etc. Just lovely!

For sure it is unencrypted, so it is vulnerable to man-in-the-middle attacks.

ftps? Not to be confused with SFTP.

I'm sure the majority of people that still use FTP aren't relying on a browser for access but people still use it. Why not just deprecate standard FTP and only support FTPS and SFTP?

https://en.wikipedia.org/wiki/File_Transfer_Protocol#Securit... lists many issues. The worst is that FTP transmits user names and passwords in cleartext.

Having said that: nowadays it isn’t uncommon to say “FTP server” for a server running SFTP, its secure replacement, so it isn’t clear to me what exactly is being removed from Firefox.
