Rated 5 out of 5 stars

Hello, I have a problem with FireFTP 2.0.20. During the update, the message is that the version is not compatible with Firefox 31.
Update 16/08/14. Thanks for the info. Now I do know.

This review is for a previous version of the add-on (2.0.20.1-signed). 

This is a known issue and problem with Firefox's website:

You'll have to go currently to this page to get a version that works for 31:
