And some things don't even work. For instance, my dentist had a sign "rate us here on google" with a QR code. That code didn't work on my phone. I eventually figured out that it works fine in Chrome, but doesn't work in Firefox. In fact, there's no way to rate businesses on Google.com from Firefox on my phone. The links just aren't there, and going directly gives a 404. Everything works fine on Chrome. That's obviously done maliciously by Google, of course.
