Even though i have Proton VPN blocking trackers and use firefox with arkenfox EFF always says my browser has a unique fingerprint. Same with Mullvad browser and Tor. When I switched Tor to “Safer” it said near unique fingerprint, and only when i switched it to safest did it say i am protected from fingerprinting
from my results id guess that it has no fingerprit thanks to no javascript, but 90% of websites are useless without js
With the right chemicals you can burn off your fingerprints
not forever
Depends how deep you go!
