Hi cocniaz5,

When creating the Authenticator, do you remember if you downloaded the recovery codes ?

Try searching your computer for Firefox Recovery Codes.txt

"If you don't remember saving your recovery code, check if your file was downloaded and saved with the filename <your_email> Firefox Recovery Codes.txt. "

Reference : What if I'm locked out of Two-Step Authentication? {link}

I lost my two-step authentication device, can’t find recovery codes and don’t have a logged-in device

You will have to create a new Firefox Account with another email address if you lost access to the authenticator app and possible recovery codes as written in the above linked article.
