Mullvad Browser
FreeTor Browser's anti-fingerprinting, without the Tor network
A privacy browser developed jointly by the Tor Project and Mullvad. It takes Tor Browser's mature anti-fingerprinting stack and removes the Tor network itself — every user presents a nearly identical browser fingerprint while traffic goes over your own connection at normal speed.
Why we picked it
Cookies are not the only way to track you. Browser fingerprinting is harder to defend against: your screen resolution, time zone, font list, graphics card and language settings combine into something that often uniquely identifies a device — even after clearing every cookie and using private mode.
Tor Browser handles this best, because it makes every user look identical. But the Tor network is slow and many sites block its exit nodes.
Mullvad Browser separates those concerns: keep the anti-fingerprinting, drop the Tor network. It is developed by the Tor Project — the same people behind Tor Browser — in partnership with Mullvad, based on Firefox, MPL-2.0.
What you get:
- A uniform fingerprint. Standardized window dimensions, a unified font list, a fixed time zone, and canvas and WebGL fingerprints neutralized. You look like every other Mullvad Browser user.
- Maximum-strictness defaults: third-party cookies blocked entirely, all data cleared on close, uBlock Origin included, telemetry disabled.
- Normal speed, since traffic does not route through Tor.
The crucial point to state: it protects who you are, not where you are.
Your IP address remains visible to the sites you visit and to your ISP. Mullvad's business is selling VPN service, and this browser is designed to pair with one — a VPN hides the IP while the browser hides the fingerprint. But the browser itself is entirely free, requires no Mullvad account and does not require buying their VPN — use it with any VPN, or none, accepting that you lose the IP-layer protection.
Other things to note:
- It is not a daily driver. Wiping all data on close means never staying logged in, and the fingerprinting defenses make some sites misbehave. Treat it as a second browser opened when you need anonymity, with LibreWolf or Firefox for everyday use.
- Do not install extra extensions. Extensions make your fingerprint distinctive, defeating the entire "identical to everyone" premise. Counterintuitive, but important.
- Do not resize the window. The fixed default size exists to unify fingerprints; maximizing leaks your screen resolution.
For genuine anonymity — hiding your IP and resisting traffic analysis — you still want Tor Browser or Tails.
