Don't forget about WebRTC: https://github.com/diafygi/webrtc-ips https://github.com/diafygi/webrtc-ips If you have WebRTC enabled, any website can determine both your local IP address (e.g. 192.168.1.1) and your globally-addressable IP address. The combination of these is essentially unique, and can even be better than cookie tracking or browser fingerprinting. It's possible to disable WebRTC in Firefox, but AFAIK not in Chrome/Chromium[0]. As for Firefox Hello and Pocket integration, you can turn these off if you want, but I'm 99% certain that they don't actually send any data about you unless you actually use them.
