FireFox add-ons message : 

FireFTPFTP client for Mozilla Firefox.After 13 years and 25 million downloads later, Firefox has officially removed FireFTP and FireSSH support from the browser. Thus, I've ended support / development of the addons. I recommend switching to Waterfox to continue using the addons.
