who it's for

Who Mullvad Browser is for#

Researchers separating browser identities

the problem

The problem it solves#

Ordinary browsers expose many signals that can be used to track users across sites, even when cookies are blocked. Fingerprinting, telemetry, and permissive defaults make private browsing harder than opening an incognito window.

Some users want Tor Browser's anti-fingerprinting ideas without routing all traffic through the Tor network. That creates a need for a hardened browser profile that pairs well with a trusted VPN or privacy-focused network setup.

how Mullvad Browser solves it

How it solves it#

Anti-fingerprinting defaults

Mullvad Browser is designed to reduce browser fingerprinting, helping users blend into a more consistent browser profile.

Built with Tor Project expertise

The browser is developed with the Tor Project, bringing privacy-browser lessons into a non-Tor-network browsing option.

VPN-friendly privacy model

Mullvad positions the browser for use with a VPN, separating browser hardening from network routing choices.
