Firefox Developers the plan to completely discontinue support for the FTP protocol, which will affect both the ability to upload files via FTP and to view directory contents on FTP servers. In the upcoming Firefox 77 release, scheduled for June 2, support for FTP will be disabled by default, but the "network.ftp.enabled" setting will allow re-enabling FTP in about:config. In ESR builds of Firefox 78, support for FTP will remain enabled by default. The reason for discontinuing FTP support is the insecurity of this protocol against modification and interception of transit traffic during MITM attacks. According to Firefox developers, there are no reasons to use FTP instead of HTTPS for resource downloads in modern conditions. Moreover, the code supporting FTP in Firefox is very old, creates maintenance problems, and has a history of revealing a large number of vulnerabilities in the past. For those in need of FTP support, it is recommended to use external applications that act as handlers for ftp:// URLs, similar to how irc:// or tg:// handlers are used. It is noteworthy that earlier in Firefox 61, downloading resources via the FTP protocol from pages opened via HTTP/HTTPS was already prohibited, and in Firefox 70, rendering content of files downloaded via FTP was discontinued (for example, images, README, and HTML files stopped displaying when opened via FTP and instead a file download dialog was immediately shown). In Chrome,
there is also a plan to eliminate FTP — the gradual process of disabling FTP support by default (for a certain percentage of users) has begun, and in Chrome 82, a complete removal of the code ensuring FTP client functionality is planned. According to Google, FTP is now barely used — the share of FTP users is about 0.1%.
