not working on FF 18.0.1 Rated 5 out of 5 stars

I've been using this great add-on for years. Now, after updating to FF 18.0.1, the top toolbar of FireFTP doesn't work at all. I can't access my saved passwords. Also, when I click on each of menu item, on 'tools' sub-menu, none of them opens anything. I'm using FF on Win 7 64bit.

This review is for a previous version of the add-on (2.0.7.1-signed).
