Can't Access Firefox with Authenticator

### Describe the issue

Hi!

I just upgraded my Firefox browser and now it requires that I log in using Authenticator. I've added the extension but I can't get it to work. In my attempts to get something to work, I'm now locked out of Firefox. But the Catch-22 is my only way back into the account is through Authenticator.

Here's all I understand so far:

The Authenticator Extension appears to have three options to interact with it, none of which I can figure out:

a) I need to add my first account. It says, "No accounts to display. Add your first account now." I've looked at the instructions on how to open an account at _https://authenticator.cc/docs/en/quickstart_ but nothing responds as described.

b) The QR Code doesn't respond. It just says, "Capture Failed. Please reload and try again." Also, I'm unsure if Firefox uses the QR code.

c) The manual entry asks for Issuer (Authenticator Extension, right?) and Secret. I have no idea what to put in there. Apparently, a Secret is provided at some point, but I've not seen it yet.

So sorry for being completely lame here. Appreciate any help you can offer.

Thanks so much, Laurie

### Browser

Firefox

### Browser Version

Firefox 100

### Extension Version

6.3.4

Beginne damit, den Kontoeinrichtungsablauf in Firefox 100 mit Authenticator Extension 6.3.4 zu reproduzieren, und prüfe die im Bericht beschriebenen Pfade für die QR-Erfassung und die manuelle Eingabe. Als abgeschlossen gilt, wenn ein reproduzierbarer Fehler in der Extension mit umsetzbaren Details identifiziert wurde oder bestätigt wurde, dass es sich bei dem Bericht um eine Frage zur Einrichtung oder zum Kontozugriff und nicht um eine Codeänderung handelt.
