Aren’t those browser settings and not user settings? I see your point and maybe those should be user settings, but saying that “Firefox on android keeps turning it’s Data Collection options on” is misleading

Really? Turned them off a long time ago, never seen it changing (checked now too just in case)

I see your point, but seems the same effort as a QR scan

Why is NFC needed in this case? Regardless of this being a potential security risk (which it is, but it’s not my point here), does it provide any additional value over a QR scan, which can easily store a URL or a contact information?
