Works perfectly on FF 13 Rated 5 out of 5 stars
I give this one 5 star coz it's awesome. Works perfectly with Keepass v2.19 I just installed after recovering my system 2day ago.
I wonder why some say it doesn't work, and as a result give this awesome addon bad rating. It works great! You only have to follow the small rigorous steps outline by the developer to get things working fine.
I use this as well as the sister, Chrome version, and both work just too well using the same Keepass database!
