About two years ago, I created an account on Mozilla, and by then I'd already set up two-step authentication using the app's Authenticator. But then I had to reset Windows and lost my backup keys and other stuff. Soon after, I experimented with other browsers and forgot about Firefox (I also deleted the Firefox profile in the Authenticator app). Now I've decided to log into my account, but since I can't log in without the app, I figured there's an option to log in using the email linked to the account (I have access to it), but for some reason, they're asking me for an account recovery key. So, I know my email address and have the password for it, but I can't log into my account without the Authenticator app. To try this alternative, I need to know the account recovery key, but I've lost it too. So, I'd be very grateful if anyone knows a solution to this problem. For reference, I also logged out of my Mozilla account on other devices and I haven't received any emails related to this situation (like checking email, etc.).
