Browse Privately with Mullvad Browser

What is Mullvad Browser?

Mullvad Browser is a privacy-first web browser built in collaboration between the Tor Project and Mullvad VPN. It's a hardened fork of Firefox designed to make you look like every other Mullvad Browser user — defeating fingerprinting at its core.

• •Built on the same anti-fingerprinting technology as Tor Browser, but without the Tor network
• •Zero telemetry — unlike Chrome, Edge, or even standard Firefox, Mullvad Browser sends no data back to anyone
• •Completely free and open-source
• •Pairs perfectly with a VPN for comprehensive privacy protection

Step 1. Download

Download Mullvad Browser from the official website:

• •Visit mullvad.net/browser
• •Available for Windows, macOS, and Linux
• •Always download from the official source — never from third-party sites

Step 2. Install

Installation is straightforward on all platforms:

• •Windows: Run the .exe installer and follow the prompts
• •macOS: Drag the Mullvad Browser app into your /Applications folder
• •Linux: Extract the downloaded tarball and run the start-mullvad-browser.desktop file

Mullvad Browser installs as a standalone application — it won't interfere with your existing Firefox installation.

Step 3. First Run

When you first launch Mullvad Browser, you'll notice it's ready for privacy out of the box:

• •uBlock Origin comes pre-installed and active — no need to hunt down an ad blocker
• •By default, every session runs in private mode — cookies, history, and site data are automatically cleared when you close the browser
• •The browser window is a fixed size to prevent fingerprinting via screen dimensions
• •Fonts, WebGL, and other identifiable features are standardized across all Mullvad Browser users

Step 4. Key Privacy Features

Mullvad Browser includes several layers of protection that set it apart from regular browsers:

• •Zero telemetry — No usage data, crash reports, or analytics are ever sent anywhere. This is a fundamental design choice, not just a setting you toggle off
• •Anti-fingerprinting — The browser actively resists fingerprinting by making all users appear identical. Websites see the same canvas fingerprint, font list, and browser attributes regardless of your actual hardware
• •Private by default — Every window is a private window. No convincing needed — it's the only mode
• •No browser sync — Unlike Chrome or Firefox, there's no account system and no cloud sync. Your browsing data stays on your device

Step 5. Configure for Your Needs

While Mullvad Browser is privacy-hardened by default, you can adjust a few settings for convenience:

• •Bookmarks: These do persist across sessions — you can safely bookmark sites you trust without compromising privacy
• •Homepage: Set a custom homepage in Settings. Consider a privacy-respecting search engine like DuckDuckGo or Startpage
• •Extensions: Be careful — each extension you add makes your browser fingerprint more unique. Stick to uBlock Origin (already installed) and consider only essential additions

Step 6. Use with a VPN

Mullvad Browser protects your browser fingerprint, but it doesn't hide your IP address. For complete privacy, pair it with a VPN:

• •Hide your IP address — A VPN masks your real location from websites and your ISP
• •Encrypt your traffic — Everything between your device and the VPN server is encrypted, protecting you on public Wi-Fi and preventing your ISP from seeing what you browse
• •Mullvad VPN is the natural pairing — same company, same privacy philosophy. But any no-logs VPN with a proven track record works well

Combined, Mullvad Browser + a VPN gives you protection against both fingerprinting (who you appear to be) and tracking (where you're connecting from).

Quick Tips

• •Mullvad Browser clears all browsing data on close by default — this is a feature, not a bug. Use bookmarks for sites you want to revisit
• •Use Mullvad Browser for sensitive browsing — banking, health searches, political research — and keep your regular browser for everyday use like streaming and shopping
• •Keep Mullvad Browser separate from your everyday browser. Different use cases, different tools — and the separation prevents cross-contamination of your browsing profiles
• •For maximum privacy, pair Mullvad Browser with a no-logs VPN and a privacy-respecting DNS provider
