I have a long-standing Firefox account under a primary email ("email1") with a secondary email (email2). I've gotten locked out. Firefox won't let me sign in under email2; it requires email1 for sign in. For email1, I know the password but have set up two-factor authentication. I have my authentication device and authenticator app. But, perversely, there is no app entry for Firefox. I have Microsoft's app but I have used it only for Microsoft-related sites. How the Devil I could have enabled 2-factor authentication but lost the Firefox entry for it in the app, I neither know nor understand. I have access to both email1 and email2. I know all the answers to every secret question I've ever answered. I know everything about me there is to know. I am me after al. Is there any information, any combination of facts, that might satisfy Firefox that I own my account and let me turnoff 2-factor authentication? For example, I have both Chrome and Safari accounts set up with the same username and emails, and have access to them. My user name is absolutely unique across the internet. I guarantee that no one other than me has ever used it or could ever duplicate the scheme I used to create it. I have so many accounts set up under that username that it must be patently apparent that the one at Firefox in that username is mine. Perhaps that would satisfy Firefox that I own the same-configured account at Firefox. Can I get the attention of a live person at Firefox, one that can reason independently, one that can recognize the obvious and certain fact that the account belongs to me? What can i do? Please don't tell me nothing. I don't care about losing the data. I just want my email addresses freed up so I can open another account.
