A while ago, it removed the support for the Adobe Flash Player plugin to protect users from supercookies and improve the browser’s performance and stability. This is not the first time Mozilla had removed its popular features while going through an update. Previously, Mozilla software engineer Michal Novotny also said that a part of the FTP code is ancient, unsafe, and hard to maintain, and they had found a lot of security bugs in it in the past. Mozilla has been removing the FTP support from its platform probably because it is not a secure protocol to prefer HTTPS for downloading resources.

The users will have to depend upon a dedicated FTP browser to access remote servers from now on. The users will not be able to transfer files from one host to another using Firefox anymore. This means that extensions will help the users launch an FTP application to handle certain links.įirefox on Android will also be affected by this FTP support removal. Mozilla blog post referred that after the removal, the places where “an extension may pass ‘FTP such as filters for proxy or web request should not result in an error, but the APIs will no longer handle requests of those types”.Ĭaitlin Neiman, the Mozilla add-ons community manager, informed the post that they added FTP to the list of supported protocol_handlers for browser extensions to help the users after removing the implementation. Mozilla has also announced that it will attempt to pass the FTP links off to an external application, “After FTP is disabled in Firefox, the browser will delegate ftp:// links to external applications in the same manner as other protocol handlers”. The implementation will also be removed from Firefox 88 on April 19, 2021and for Firefox 90, it will be removed by June.
