Mullvad Browser 15.0.21 for Windows

Mullvad Browser 15.0.21 is a free, privacy-focused web browser developed by Mullvad together with The Tor Project, Inc. It is based on Tor Browser and shares its protections against tracking and fingerprinting, but connects to the internet directly or through a VPN of your choice instead of the Tor network. The browser is open source under the Mozilla Public License 2.0, and you can download Mullvad Browser for Windows from mullvad.net.

Who Mullvad Browser is for

Mullvad Browser is aimed at people who want strong protection against online tracking without the slowness of the Tor network. Ordinary browsers can be identified by a combination of small details: installed fonts, screen size, time zone, graphics card behaviour and more. Advertisers and data brokers use that fingerprint to follow you across sites even without cookies. Tor Browser counters this by making all users look alike, and Mullvad Browser brings the same approach to everyday browsing. It works well together with a trustworthy VPN, which hides your IP address while the browser hides everything else. It suits journalists, researchers and anyone who does not want their browsing profiled. It is less convenient for people who rely on many extensions, custom themes or saved logins across sessions, because the browser deliberately resets and standardises much of that. You do not need a Mullvad VPN subscription to use it. Sites that depend on heavy tracking may occasionally break or ask for extra verification.

Key facts

Installation

1. Download the Windows version from the official Mullvad Browser download page.
2. Install and start it; the default settings are already privacy-oriented.
3. Leave fingerprinting protections as they are; changing them can make you stand out.
4. Use a VPN alongside it if you also want to hide your IP address.

The source code is on GitHub, and development news appears on the Mullvad blog, for example the post on the alpha moving to Firefox rapid release.

Tips

• Avoid installing extra extensions; each one makes your browser more unique.
• Expect to log in again after closing the browser, since private mode is the default.
• Keep it updated; privacy tools are only as strong as their latest fixes.
