the only way to actually prevent fingerprinting is to never connect. your ip, os, tls cryptographic protocols (or lack there of), screen resolution, mouse speed+movement, keystrokes+keyboard layout and much much more all can be used to fingerprint a user. even the reduction of all these points can be a fingerprint.

since most of those are unlikely to actually happen (yet) with the usual dragnet ad surveillance, just using hardened firefox (arkenfox/librewolf/mullvad browser) with a vpn or just tor browser is sufficient.
