2FA recovery codes not working.

I have 10 recovery codes generated when enabling 2FA, but unfortunately entering each one does not bring the expected effect. I also have a 58-character code, but I do not know what it is for. I have checked on other devices and do not have a device from which I can disable Two-step authentication. I understand this operation is non-reversible and I will lose access to any Sync data that is not already on a device.

Did you ever reset the password for that Firefox account?

You need a fresh login to the website to be able to disable 2FA or generate new recovery codes via the settings page.
