I just bought the family version and created an account on FireFox but it does not look good.
First I was given an option to import my old password, but after the first dialog it froze and couldn't get back to how to import my old passwords from lastpass.
Next, I tried to install the extension from Keeper's page, but that link doesn't work, However after searching for it from within firefox add-ons page I found it, installed it but it's not clear how to use.
It's my first day, chose b/c of some reviews online, but I am getting the impression that it's very buggy, crossing fingers.
