I tried to activate a credit card today. Firefox is the default browser on my iPhone. I took a photo of the QR code and Firefox took me to the issuer's site - no problem so far. But when I tried to switch back and forth between Firefox and my password manager app (1Password), every time that I captured the login information and went back to Firefox, the browser switched to my Home page (Yahoo) and closed out the issuer's site!
I ended up having to fire up the laptop to complete the activation. NOT user friendly!! I have now deleted Firefox and made Safari my default browser
