Mullvad Browser is a desktop web browser from Swedish company Mullvad. It was developed with the Tor Project to offer enhanced privacy protection. The browser blocks third-party trackers and uses techniques (like uniform window sizes) to make users’ browser fingerprints identical, reducing tracking. It is open source and free of charge and can be used with or without a VPN. Mullvad emphasizes that no telemetry or user data is collected by the browser. The tool is intended as a companion to privacy tools (e.g. using it alongside a VPN). The official site focuses on privacy features; no founding date is given.
