My firefox account sign in uses my TRUE email address. BUT, when I go to settings it shows a dead email address of mine under my picture. There is o setting that I can find to change/update my email address. There is an option to add a secondary email address but it won't take it as I can and am logged in with my current yrue email. So, does anyone know how to delete the dead email link all together and replace it with the correct, signed in one? I need the dead one to nonexist everywhere because anything sent there will never come to me. Those things could be Tax INFORMATION to Financial INFORMATION.
