For some reason, desktop FF keeps asking for syncing with mobile when I'm pretty sure it is, as I can still use some feature, though some dont work like sending tabs. So when I go to firefox on mobile, making a new tab and using the camera to scan the QR code. It doesn't work. When I tried it a few days ago, it told me something went wrong, and now it says that I'm using my iOS camera app instead of the FF app. Hopefully I explained it well.
