I would like to change my primary email on the account and my profile shows that there is currently no secondary email. I keep inputting a secondary email address that I could then reset to be the primary but Firefox keeps responding that the proposed secondary email is already confirmed by another user. The proposed secondary email is under my full control and it would not be confirmed as a secondary email for anyone else. While attempting to solve this mystery, I did attempt to sign in under the proposed secondary email. I thought that if I were successful, I could close out that account. Unfortunately, while it appeared to accept the email address and a password saved on my hard drive, I also received an error message that said that I needed to sign in under the primary email. The purpose for all of this is that I am changing to a new computer, will want to operate it without the old primary email address, and want all of my settings and history from the old computer to transfer over. Please advise. Thanks.
