My wife and I each have accounts at Mail2world.com. The login entails "Login Name" (i.e. user name), "domain" (i.e. our common chosen domain mail2xxxxxx), and password. Firefox considers Mail2world's "domain" field to be the Username field and I can't see where it saves the Login Name" (i.e. user name). Firefox has saved one set of login credentials, but how can I persuade Firefox to save two separate Login Names and passwords with the same "domain" field?
