I have followed the steps to remove a saved password, but it hasn't actually removed it from firefox as there is a general password and an admin password. I accidently saved the general password so unable to open as an admin. Thank you for your help.

I have followed the steps under security within Firefox to remove a saved password, but it hasn't actually removed it. I removed it and then tried to sign on again and it automatically went to the saved password. This URL uses an admin and a general password and I accidentally saved the general password so unable to open as an admin. When I go to the URL to enter my admin password it goes to the saved general password. As administrator for my church website, I can't get into it and make changes without using my admin password.
