Rated 5 out of 5 stars

I completely love it, the only thing that kinda bothers me is that it asks for permission multiple times when entering my info on a text field, one time is cool but 3 times gets a little anoying. Overall an awesome addon for OS X

This review is for a previous version of the add-on (1.0b1). 

There are some cases where I think Firefox is just looking up the password for accounts it doesn't need to (ie. if you have multiple account names saved, it will ask for the keychain password even for accounts that do not match).

The extension ensures that we only ask the keychain for the password if Firefox asks for it. And the keychain shouldn't prompt you unless you ask for the password or your keychain is locked. I assume if you say "Always allow" that you are no longer prompted?
