The protocol is no longer supported in Firefox starting with version 90. The open-source group initially announced plans to remove FTP support in Firefox in March 2020 – a couple of months after Google deprecated the protocol in Chrome – and disabled it by default in Firefox 88.

“Aligning with our intent to deprecate non-secure HTTP and increase the percentage of secure connections, we, as well as other major web browsers, decided to discontinue support of the FTP protocol,” Mozilla explained. Secure variants do exist, including one that leverages SSL/TLS (FTPS), or the SSH File Transfer Protocol (SFTP).Īlmost since the beginning, FTP has been supported by all major browsers, but security problems have resulted in decreased usage, as well as deprecation in favor of more secure alternatives.įurthermore, FTP has been abused in various malware distribution campaigns, some of which involved the compromise of FTP servers to leverage the protocol for payload delivery. H owever, because data is transmitted unencrypted, the protocol has long been considered insecure.

Mozilla has completely removed support for the File Transfer Protocol (FTP) from the latest release of its flagship Firefox web browser.īuilt on a client-server model architecture and in use for roughly five decades, FTP allows for the easy transfer of files and folders between computers.
