Where Privacy isn’t just a Setting

Mullvad Browser is arguably the best privacy focused browser for those tired of being tracked, fingerprinted, and profiled online. Developed in collaboration with The Tor Project, this browser gives you strong privacy defaults, robust anti-fingerprinting, and zero user tracking—right out of the box. Whether you’re a privacy pro or a curious beginner, it’s designed so anyone can browse without constantly tweaking settings.

It’s built for privacy from the ground up, stripping out telemetry, enforcing private mode, and offering tools to reduce website tracking and fingerprinting. Unlike most mainstream browsers, it doesn’t store browsing history or cookies after your session, making it an excellent privacy focused browser.

Under the hood

Mullvad Browser is built on Mozilla Firefox ESR (Extended Support Release)—a stable, community-trusted engine. Unlike Chrome– or Chromium-based browsers, the Mullvad VPN browser inherits Firefox’s flexibility and security but disables telemetry and minimizes built-in code that could erode privacy. It’s open-source, with active development from both Mullvad and key volunteers from The Tor Project.

Updates arrive regularly, bringing the latest Firefox ESR security patches and feature improvements downstream. All source code is public, with development happening transparently on GitHub, attracting privacy advocates from around the world.

Privacy and Security

Let’s talk specifics—this is why you’d want to enable anti fingerprinting in Mullvad Browser. The browser standardizes things like reported browser version, operating system, timezone (always UTC), fonts, and more, making it difficult for websites to single you out. Even features like keyboard layout and canvas fingerprinting are “bucketized” so large groups of users share identical fingerprints.

There’s no telemetry, crash reporting, or unnecessary connections (“phoning home”). Cookies and cached data are cleared when you close the browser. The browser runs in privacy mode by default, refusing to remember history or persistent cookies past your session. Content, script, and tracking protection—including robust uBlock Origin support—further shrinks your online trail. If you’re wondering about built-in VPN browser integration: while Mullvad Browser does not have a VPN built in, it’s optimized to work perfectly with any VPN, especially Mullvad VPN. With a VPN running, you hide your IP and amplify your privacy.

Mullvad Browser delivers on privacy, but keeps things usable. It bundles privacy-respecting search engines by default, has a handy “New Identity” button (resetting your session and cookies with a click), and features granular security settings (“Standard”, “Safer”, “Safest”)—letting you control what scripts or media can run on sites. Its default “letterboxing” window resizing defends against screen size fingerprinting.

Mullvad and Tor both are built by the same development team and share fingerprinting, anti-tracking, and anonymous browsing features. Tor Browser routes your traffic through the Tor network for maximum anonymity, but may slow your connection and can trigger capchas. Mullvad Browser connects via your normal internet connection, but runs best with a trusted VPN—like Mullvad VPN—to hide your IP.
