I wonder how much DNS blocking would contribute to a unique browser fingerprint? Like a tracker could use a range of domains, some of which are known to be blocked by certain end-user software, to build a fingerprint.

I currently use a vanilla LibreWolf which has uBlock Origin and reasonable defaults out of the box for this reason.

My only other line of thinking is that a combination of DNS, IP and in-browser blocking could be more effective than just in-browser alone.
