Mullvad Browser Review (2026): Swedish, Free and Built with Tor

What is Mullvad Browser?

Who is behind Mullvad Browser

Mullvad Browser is published by Mullvad VPN AB in Gothenburg, Sweden – the company known for Mullvad VPN, which launched in March 2009. Mullvad VPN AB is owned by its parent company Amagicom AB, and both are 100% owned by the founders, Fredrik Strömberg and Daniel Berntsson, who are still active in the company. There are no outside investors listed.

The browser itself was developed by the Tor Project at Mullvad’s request. Mullvad describes it as “a Tor Browser without the Tor Network”: it uses the same privacy protections as Tor Browser, but connects to websites directly or through a VPN of your choice. Mullvad says it earns no money from the browser – it is free, open source and needs no account. The code is on GitHub, described as “Made in collaboration between” the Tor Project and Mullvad.

Where Mullvad Browser hosts your data

A browser keeps your data on your own computer, and Mullvad Browser keeps less than most: private mode is on by default, so no cookies or history are saved between sessions, and there is no sync service. What the browser does send by default are update checks for the browser, its extensions and its filter lists. Mullvad’s website and download servers run on its own Swedish network (31173 Services AB, AS39351), not on a US cloud.

Mullvad Browser pricing

Mullvad Browser is free of charge, with no premium tier, no account and no in-browser upsell. Mullvad says it makes no money from it. The browser works without a VPN, but Mullvad points out that without a trustworthy VPN your IP address is not hidden. If you want one, Mullvad VPN is sold separately; you can also use any other VPN.

Compared with Chrome, which is also free, the difference is the business model: Chrome comes from Google LLC, whose revenue is advertising, while Mullvad Browser is funded by a company that sells VPN subscriptions and does not run ads.

Privacy and anti-fingerprinting

Mullvad Browser does not try to block everything – it tries to make every user look the same. The current stable release, 15.0.24 (30 September 2026), is based on Firefox 140.17.0esr, so it uses the Gecko engine rather than Google’s Chromium. On top, it turns on Firefox’s resist-fingerprinting mode, limits fonts, removes some hardware APIs, blocks reading of WebGL pixels and adds letterboxing so your window size does not reveal your screen. Third-party cookies are isolated per site, uBlock Origin blocks trackers and NoScript powers the Security Level setting. Telemetry is removed.

The settings are standardised, and Mullvad discourages changing them or adding more extensions, because anything that makes your browser unique makes you easier to track. Mullvad also says that more aggressive blocking can backfire and reveal your identity. The browser runs on Windows, macOS and Linux; Mullvad says it is not available on smartphones.

What users say about Mullvad Browser

There are no Trustpilot reviews for the browser itself. Mullvad’s company profile on Trustpilot has 3.2/5 from 190 reviews (checked 25 October 2026), but the profile is listed as a VPN service, it is unclaimed, and none of the reviews mention the browser.

Pros and cons

Verdict on Mullvad Browser

Verdict: Mullvad Browser is the most private browser you can get from a European company: Swedish, founder-owned, built with the Tor Project, free and open source. The price of that privacy is convenience – no mobile app, no sync and a clean slate every session – so it works best next to an everyday browser like Vivaldi, for the sites where privacy matters most. Best for: privacy-minded people who want to stop being tracked across websites. Not for: anyone who needs Chrome-style sync between phone and computer.

Mullvad Browser is ranked #3 in Best European alternatives to Google Chrome and in Best European browsers.
