Have you tried uninstalling and reinstalling FireFTP? In order to uninstall an extension, please do the following: #From the Firefox window click the Firefox button at the top left and select ''Add-ons'', or, if the Firefox button is not shown, click the ''Tools'' menu and click ''Add-ons''. #Once the Add-on Manager has opened in a new tab, click the ''Extensions'' button on the left side of the window. #You should now see a list of your installed extensions on the right side together with buttons on the right side of each extension. #To remove an extension from Firefox, simply click the ''Remove'' button. You should see a message that informs you about the successful removal of the add-on. #Note that some add-ons require a Firefox restart to be removed completely. To perform a Firefox restart after the add-on removal, click the ''Restart now'' link in the message.
