Firefox is not letting me change my email because it says the one I am trying to change it to is already my account email, but it is not the email that shows in my account information or the one Firefox regularly sends emails to. I would appreciate any help changing the account email, but when I search for help, all I find are instructions for changing my primary or secondary email addresses, and those instructions are not working. Details below (with fake email names): I'm losing access to my email account, so I logged into Firefox to change my account email. My account displayed: Primary email: first@olddomain.com It did not show any secondary email account. I clicked to add a secondary email and typed in first.last@gmail.com Firefox gave me the following error message: "Secondary email must be different than your account email" To test it, I added a different secondary email, first@differentdomain.com. I made first@differentdomain.com primary and then deleted first@olddomain.com. Then I tried again to add first.last@gmail.com as a secondary email but got the same error message. Is the "primary email" different from the "account email"? Where can I find the account email to change it? Thank you!
