Cannot change my email address

jscher2000 -... replied

I cannot change my email address to my new email address.

When I try to follow the primary email change procedure, after entering my new address, I receive a message: "that account already exists."

My new email address is: [edited] @gmail.com My old email address is [edited] @aol.com

I no longer have access to my old email address [edited] @aol.com which changed years ago.

I have never had any identity confusion with my current gmail address, [edited] @gmail.com

This situation may have happened from my previous attempts to update my primary email address. Could you send me a verification code to [edited] @gmail.com so that I can resolve this situation?

Thank you.

Unfortunately since you no longer have access to the primary email that created the account that is need to verify the change. This is a user help forum no one has access nor can they send msgs to others users.

Hi David, that is the error when you try to add your Gmail address as a "secondary" address on your Mozilla Account? It sounds as though either you or someone else created a separate Mozilla Account using that address. If you search your Gmail mailbox, can you find any evidence of that?
