Scan QR Code doesn't work in the FireFox add-on.

[Jimbo-Jim]

I have given the add-on both of the two permissions it requires in the FireFox's add-on and themes menu, but when I click on the add-on and click "Scan QR Code" I get a prompt from FireFox saying "Authenticator requests additional permissions." If I click "Allow" the prompt goes away but nothing happens, I'm not asked to scan the QR Code. Not sure if it's that it can't see the QR Code or if it's an issue with permissions? I've only been using the add-on for a week but this function has never worked for me.

Disabled and re-enabled the add-on and all seems to work as expected now.
