- IPs are relevant
- Your DNS server is relevant, especially if it's google's or cloudflare's or youe ISP's DNS
- ETags can be used like fingerprints
- LastModified can also be used for fingerprints
- Pragma can be abused for long-living fingerprints in your Browser Cache
- AdMob has ultrasonic support. Not kidding, ads can be delivered to your phone while you watch TV - via unhearable sound signals. [1] usually called uXDT or XDT.
- Chrome has multicast DNS support to discover surrounding devices (and Browser instances). Check DNS-SD for details, and what can be discovered.
- Also the data for Chrome's locally trained neural net (aka FLoC) is inside the profile folder but won't be cleared with Browser History.
- (unlikely) TLS fingerprint is usually coupled with User-Agent on the server side, so rotating your User-Agent is pointless if you don't change the TLS fingerprint (which you can't without recompiling the Browser Engine).
Welcome to the new world. I miss the good ol' HTTP/1.1 days.
