According to Google FTP, it is hardly used anymore: the proportion of FTP users is about 0.1%. On the side of Firefox's competition in "Chrome" a plan was also adopted to get rid of FTP support in Chrome 80.Īs the process of gradually disabling compatibility started with FTP by default (for a certain percentage of users) and in Chrome 82 it is planned to completely remove the code provided by the FTP client. "We are doing this for security reasons," said Michal Novotny, a software engineer at Mozilla Corporation, before adding: "FTP is an insecure protocol and there is no reason to prefer it over HTTPS for downloading resources," "moreover, some of the code FTP is very old, insecure and difficult to maintain and we have encountered many security bugs in the past.Īnd it is important to remember that previously in Firefox 61 it was already forbidden to download resources through FTP from pages opened via HTTP / HTTPS.Īnd in Firefox 70 the rendering of the content stopped of the files downloaded via ftp (for example, when it was opened via ftp, images, README and html-files, and immediately the dialog of loading a file to disk began to appear). In 2021, it is planned to completely remove the code related to FTP.

On ESR versions of Firefox 78, FTP support will remain enabled by default. In the Firefox 77 version, scheduled for June 2, FTP support will be disabled by default, but the "" setting will be added to the browser settings page "about: config" to allow users interested in continuing to have support enabled to return FTP. With that Firefox developers have come up with a plan to completely stop supporting the FTP protocol, which will affect both the ability to upload files via FTP and the display of the contents of the directories on the FTP servers. In 2018, an option to disable FTP support was added in Mozilla Firefox, but this option was never enabled by default, however, it allowed users and organizations to manually disable FTP support. And is that the reason for this it is because it is a protocol that has started to depreciate since the launch of Firefox 61. Mozilla recently announced that it intends to remove support for the FTP protocol.
