Hello, Can you provide some additional details on what you are trying to accomplish with the QR code? I am not sure I understand the nature of the issue. In Firefox for iOS there is a QR code button that is shown to the right side of the search bar. See my attached image for reference. I am wondering if this is what you are referring to. When you click this button the Firefox App will access your phones camera to capture a picture of the QR codes wherever you encounter them. Once the scan is taken, Firefox will search for the associated webpage and pull that up for you. Let us know if your issue is related to something different and we can try troubleshooting further.
