I am locked out of my primary Firefox account due to 2FA being enabled, loss of 2FA device, and cannot locate my backup auth codes. I still have control of the primary and secondary email addresses associated with the account. It seems like that should be enough to be able to delete the account, but there doesn't appear to be any way to do that. I would be glad to send email from one/both of those addresses if it would help facilitate the account being deleted.

I also have a Firefox Relay subscription active under that account, which is why I cannot just abandon it and use a new account.
