Without using a VPN, Mullvad Browser provides the same protections against naive fingerprinting scripts as other private browsers like Firefox+ Arkenfox or Brave. If you want to configure your browser more heavily and fingerprinting is not a concern for you, we recommend Firefox instead. Other modifications would make your fingerprint unique, defeating the purpose of using this browser.

Therefore, it is imperative that you do not modify the browser at all outside adjusting the default security levels. Like Tor Browser, Mullvad Browser is designed to prevent fingerprinting by making your browser fingerprint identical to all other Mullvad Browser users, and it includes default settings and extensions that are automatically configured by the default security levels: Standard, Safer and Safest. It is developed by the Tor Project and distributed by Mullvad, and does not require the use of Mullvad's VPN. Mullvad Browser is a version of Tor Browser with Tor network integrations removed, aimed at providing Tor Browser's anti-fingerprinting browser technologies to VPN users.
