Mullvad Browser is a privacy browser launched in April 2023, jointly developed by the Tor Project and Mullvad. Built on Tor Browser’s anti-fingerprinting and hardening foundation but without the Tor network. Designed to be used over Mullvad VPN (or any VPN of choice). Ships with the same fingerprint normalization, JavaScript controls, and content-blocking as Tor Browser, with the speed of a normal VPN.
What it means in practice
The product fills a specific gap in the privacy browser market: Tor Browser has anti-fingerprinting but slow Tor routing; Brave has fast routing but weaker anti-fingerprinting; Firefox with arkenfox has strong privacy but requires manual configuration. Mullvad Browser ships with Tor-Browser-grade defaults out of the box, runs over the user’s VPN, and avoids the latency cost of Tor for sessions that do not need full Tor anonymity. The operational positioning: use Mullvad Browser for general daily browsing where you want privacy without the speed sacrifice, use Tor Browser for sessions that need network-layer anonymity beyond the VPN.
Who uses it, and against whom
Adopted by: Mullvad VPN customers extending the privacy posture from network to browser layer, journalists and operators who want a hardened browser for daily work that is faster than Tor Browser, privacy-conscious users transitioning off Chrome who do not want to manually configure Firefox via arkenfox. Adversaries: advertising and tracking networks (defeated by anti-fingerprinting and content blocking), commercial surveillance products that fingerprint across visits (defeated structurally), and the long tail of trackers in CDN-distributed analytics scripts (uBlock-equivalent built-in handles most). Less useful against: nation-state network-level adversaries who can correlate VPN-tunnel traffic, where the answer is Tor Browser plus VPN rather than Mullvad Browser plus VPN.
What you can change today
Download Mullvad Browser from mullvad.net/download/browser (verify the published checksum and signature). Use it as your daily browser for general privacy-aware sessions. Pair with Mullvad VPN or any other no-log audited VPN; the browser does not require Mullvad VPN specifically despite the name. Keep Tor Browser installed in parallel for sessions that need Tor-network anonymity beyond what a VPN provides. The split-use pattern (Mullvad Browser for daily, Tor Browser for sensitive) is the realistic operational setup for journalists and privacy-aware operators.
