Rated 4 out of 5 stars
Had some difficulties initially with version problems between KeeFox and KeePass, but the documentation clearly explains everything required to set it up.
The addon works well and has a good amount of configuration options. One minor complaint is the confusingly named "Logged In" "Logged Out" status displays (they don't refer to your login status in the current site - rather, to whether the database is loaded and ready or not). Something like "<database_name> Ready" and "No data" would perhaps be better.
