1Password was one of my test extensions and the one I use every day. It works most of the time because username/password combos are the most common autofill configurations. So common that most password managers don't consider the case where you want to autofill a password without a matching username field on the page. "Password confirmation" being the classic example. They just don't handle anything other than the main case very well.
