If you’ve added a second email address to your Mozilla account, you can make it your new primary email. This is helpful if you’re changing email providers or prefer using a different address to sign in and receive notifications.
To do this, you’ll first need to add the new email as a secondary address, verify it, and then promote it to your primary in your account settings.
