alright, I have a question. Somehow I got on the Firefox sign in screen, this is nothing I did on purpose, I just clicked on Firefox and it popped up. Anyhow, it showed a screen where I got to sign in as a 'default user'. This made no sense to me. So I made a 'new account' and I do not know how to get back to the sign on screen to change back to the 'default' screen. Does anyone know how to return back to this so I can change back to the default user?
