Mullvad Browser

Mullvad Browser is a privacy browser built by Mullvad VPN together with the Tor Project: Tor Browser's hardening without the Tor network. Private mode is on by default, telemetry is removed from the build entirely, and the goal is not to hide you but to make every user look identical, so a fingerprint identifies nobody.

That approach ships as concrete defaults. uBlock Origin filters third-party trackers, third-party cookies are isolated in per-session jars rather than shared across sites, and letterboxing rounds the window to standard dimensions so screen size cannot single you out. It runs on Windows, macOS and Linux, with or without a VPN.

Key benefits:

• Fingerprint resistance letterboxing and shared defaults give users similar fingerprints
• Tracker blocking uBlock Origin filters third-party trackers out of the box
• Cookie isolation third-party cookies stay in per-session jars, never shared between sites
• Private mode by default nothing persists between sessions unless you allow it
• No telemetry analytics and reporting are stripped from the build
• VPN agnostic no Mullvad account needed, works with any provider or none
• Open source published under the Mozilla Public License 2.0
• Signed by Tor Browser developers builds are verifiable, not just downloadable

Mullvad Browser is developed by Mullvad VPN AB, a Swedish company operating under the GDPR, in collaboration with the Tor Project. The source is public under MPL-2.0 and mirrored in the Tor Project's own GitLab, so the hardening choices can be audited rather than taken on trust, and the browser is free whether or not you subscribe to Mullvad VPN.

Ideal for people who want Tor Browser's anti-fingerprinting work for everyday browsing, at normal connection speeds.
