Mullvad Browser
Free, open-source privacy browser developed with the Tor Project that aims to make all its users look alike to websites.
In short
- Mullvad Browser is free for anyone, and runs with or without a VPN1,2.
- Desktop builds exist for Windows, macOS and Linux; the FAQ says it is not available on smartphones3,4.
- uBlock Origin and NoScript are built in and cannot be removed3.
- The browser reports a UTC timezone and a common version number, and limits which fonts pages can see, to reduce fingerprinting5.
- Firefox Sync is not supported, and the built-in password manager and phishing warnings are off3,5.
Mullvad Browser suits people who want anti-fingerprinting defaults and a preinstalled tracker blocker without paying anything1,5. Its source is public under MPL-2.06. The catch: no sync, no password manager, no phishing or malware warnings, and no phone version3,5.
Best for: People who care most about fingerprinting protection and do not need sync or saved passwords.

Plans and prices
As the vendor lists them, before tax. Prices are in US dollars unless the plan shows euros; the points use US dollars, with euros converted at the ECB rate.
Strengths
- Free, and the vendor says it earns no money from the browser1.
- Letterboxing and standardised values (UTC timezone, common version number) plus limited font access reduce fingerprinting5.
- uBlock Origin blocks third-party trackers and is part of the defence against fingerprinting1,3.
- Source code is on GitHub under the Mozilla Public License V26.
- Telemetry and crash reporting are disabled when the browser is compiled5.
Limits
- No Firefox Sync; the FAQ answers a plain No3.
- No built-in password manager, so no saved logins; the vendor recommends an external one3,5.
- No phishing and malware protection, because the checks would contact Mozilla and Google5.
- Not available on smartphones3.
- The vendor discourages extra extensions because they can aid fingerprinting3.
