I have 3 accounts on a particular website. All three account login credentials are saved in firefox however one of them (the wrong one, since it is the one I use least often) is pre-filled when I first go to the site. How do I remove the setting that one of them is pre-filled? I want just the regular drop-down choice of all three. I have deleted that accounts credentials and cleared the cache, but as soon as I add the account info again, it is automatically pre-filled instead of just listed with the other two options.
