When I first started to work with win10, I put in an address that I never used before, therefore my preferred address, I guess , would be the second address.

Is this about the email address for a Firefox Sync account?

If you have previously used this address then you can connect to it instead of trying to create a new account using that same email address.

You can try to log in to the Firefox account via this website.
