Finally uninstalled it. Restoration does not work. On top of it makes a lot of function like Cookie Whitelisting disabled. Just get one of dozens free programs that backup folder and backup Mozilla profile once a week.
I was using latest FEBE 7.3.0. When I tried to restore cookies and permissions, the Cookie Whitelisting option of Firefox stopped working. When I tried to whitelist/blacklist any cookie, they disappeared from options window after firefox restart. This is not the first time I saw this problem, so I had enough.
As mentioned in the "About this Add-on" section above, Firefox v20.0 needs FEBE v7.3.0 which is available from the FEBE homepage at http://softwarebychuck.com/febe/febe.html#latest.
Also, FEBE does NOT disable any other extensions. If you are having problems, please leave a post in the support forum and I will be glad to help.
