What is browser fingerprinting?

Sites combine dozens of small browser signals (screen size, fonts installed, canvas rendering quirks, audio stack, timezone) to build a hash that uniquely identifies your browser — even with cookies disabled and a VPN.

Can I prevent browser fingerprinting?

You can reduce it but not eliminate it. Tor Browser and Mullvad Browser actively normalize fingerprints so users blend together. Brave randomizes some signals. Chrome and Edge offer no fingerprinting protection.

Do private/incognito windows hide my fingerprint?

No. Incognito mode only blocks new cookies and history — your fingerprint is identical to your normal browser session. Sites can still link the two.

Which browsers protect against fingerprinting?

Best to worst: Tor Browser ≈ Mullvad Browser > LibreWolf > Brave (with Aggressive shields) > Firefox (with resistFingerprinting=true) > Safari > Edge ≈ Chrome.

Does a VPN hide my browser fingerprint?

No. A VPN hides your IP address but the fingerprint comes from your browser itself. You need a fingerprint-resistant browser (Tor, Mullvad) on top of the VPN to actually be unidentifiable.
