It is usually best to disable the Firefox Password Manager temporarily in cases like this.

  • Tools > Options > Security: Passwords: [] "Remember passwords for sites"

The Firefox Password Manager is not very intelligent and customizable and basically uses the first field for the name and the first password field that follows for the password.

You can consider to disable autofill by setting the signon.autofillForms pref to false on the about:config page, then at least Firefox won't fill the password.
