Not very user-friendly Rated 3 out of 5 stars

I tried it, but did not see any usage improvement in comparison with a plain KeePass + Firefox password database combo... Caveat: after installing the add-on, you could have the unpleasant impression that it erased your entire Firefox password database, but in fact it didn't (sigh)... :-) Maybe this risky step could be a bit more explicit in the HOWTO section of this add-on. Thanks in advance for your time and consideration.

This review is for a previous version of the add-on (1.1.2). 

The purpose is to store all your passwords in keepass and have it portable across browsers and computers.

If you like storing your passwords in firefox, there isn't really any reason to be using this extension.
