bye: FTP Support Is Going Away

Support for the venerable FTP protocol is being removed from Chromium. Standardized in 1971, FTP is not a safe protocol for the modern internet. Its primary defect is lack of support for encryption (FTPS isn’t supported by any popular browsers), although poor support for authentication and other important features (download resumption, proxying) also have hampered the protocol over the years.

With removal first proposed by the networking lead nearly six years ago, FTP support has been gradually pared back, first blocking such urls for subresources in Chrome 59, and later forcing FTP resources to be treated as downloads in Chrome 72. Now FTP support be going away entirely, starting in version 80, although a flag (chrome://flags/#enable-ftp) will remain available to turn it back on for a limited time.

After FTP support is removed, clicking on a FTP link will either launch the operating system’s registered FTP handler (if any), or will silently fail to do anything (as Chrome fails silently when an application protocol handler is not installed).

If your scenario depends on FTP today, please switch over to HTTPS as soon as possible.

thanks!
