Google announced its intent to remove the protocol from the browser in August 2019. In a status report on its support for FTP, Google said that so few people use FTP in the browser that it isn’t worth the effort to improve the client. Its reasons may be the same as Google’s, which is also deprecating FTP in Chrome. However, Mozilla seems uninterested in supporting these. FTP over TLS (FTPS) runs the protocol over SSL/TLS. SSH FTP uses the secure shell protocol for FTP sessions, which is encrypted. There are more secure versions of FTP available. FTP is an insecure protocol and there are no reasons to prefer it over HTTPS for downloading resources.Īlso, a part of the FTP code is very old, unsafe and hard to maintain and we found a lot of security bugs in it in the past. The real crunch will come at the start of next year, when Michal Novotny, a software consultant at Mozilla, said that the Foundation will remove FTP code from the browser altogether. Firefox Extended Support Release (ESR) will continue to have FTP turned on by default in ESR version 78. Users will be able to turn it on again temporarily so that they can carry on using FTP from within the browser. Now, Mozilla is planning to turn off FTP by default in version 77 of Firefox, which will ship this June.

These included everything from problems in the way it responded to invalid login attempts through to an inability to segment file permissions when using anonymous FTP (which doesn’t require user credentials at all). In 1999, the IETF published a draft RFC listing its various shortcomings. For example, it transmits login credentials in plain text. In its original form, the protocol is insecure. Heads up, Firefox users who rely on FTP: the browser is eliminating support for this venerable protocol.įirst written in 1971, the file transfer protocol predates TCP/IP, the protocol stack that underpins the modern internet.
