FTP (File Transfer Protocol) is one of the most classic Internet protocols. It was first born in 1971. It has gone through 49 years of vicissitudes today. Lian Po is old. The biggest problem is that it uses plain text transmission, which is seriously insufficient in security, and the transmission efficiency of small files is low.
As early as 2015, engineers from Google and Mozilla began to discuss removing the FTP protocol from future Chrome and Firefox browsers and gradually implemented it.
Chrome 76 no longer supports FTP proxy, and Chrome 80 has disabled FTP.
After Firefox 61, FTP resources will no longer be loaded into web pages and must be downloaded separately.
In 2018, Firefox added the option to disable FTP, but it has always been turned off by default. However, the stable version of Firefox 77, planned to be released in June this year, will disable FTP by default for the first time.
Of course, users and businesses can still open it manually, but eventually, Firefox will completely abandon support for FTP.
In fact, as early as 2001, 19 years ago, someone gave feedback and suggested that Firefox support the more secure SFTP protocol to replace FTP, but it was never adopted by Mozilla.
