If you no longer have access to your old email address and can't sign into your existing Firefox Account, you will need to create a new account. You cannot recover an old account without access to your email address.

If you need to make a new Firefox Account, we recommend sending a password reset request using the Forgot password option, even if you don't have access to the old email address to get the password reset link. Regardless, this will wipe your old account, removing any data that you previously had on Mozilla's servers.

If you have access to your Firefox Account and want to change the primary email address, add your new email address as a secondary email. Then when you confirm it, you will be able to make that address the primary and remove the old address.
