Mullvad Browser Overview

Mullvad released a new privacy browser: Mullvad Browser, built as a collaboration between the Tor Project and Mullvad VPN. It’s presented as combining:

  • Tor Browser–like privacy protections
  • Hardened Firefox usability

First Launch Appearance & Baseline Setup

On first run, it looks like a blend of hardened Firefox and Tor Browser, including security-hardening components similar to Firefox privacy projects:

  • Mullvad extension
    • Only useful/functional if you use Mullvad VPN
  • uBlock Origin
  • NoScript (running in the background)

Hardened Firefox Compatibility

The browser pre-configures many about:config / Firefox hardening toggles, described as matching patterns from projects like:

  • Arkenfox
  • Tor Browser

Search behavior / key difference

The setup is largely Tor-like, except for one notable difference:

  • A Mullvad search engine that shows Google results
  • But only behind a Mullvad subscription/paywall

Website Compatibility & Performance

The video claims that common sites mostly work and that the browsing experience is “usable.”

A key point: it does not route traffic through the Tor network, so:

  • Speeds are better than Tor Browser
  • While still aiming for privacy/security protections

Notable Downsides & Usability Limitations

Private mode enabled by default

Private mode is enabled by default, which affects typical account workflows. Users may need to:

  • Log into accounts every time the browser is opened

Web authentication disabled by default

Web authentication is disabled by default, which creates compatibility issues for:

  • Hardware security keys (e.g., YubiKey / hardware 2FA)

Users would need to change an about:config setting, but the speaker warns this could introduce potential fingerprinting/security concerns.

The speaker characterizes these as major usability sacrifices for mainstream account login and 2FA.

Platform Availability

  • Desktop only
  • Available for Windows, macOS, and Linux

The speaker supports desktop-only because implementing this on mobile/iOS would be harder under privacy constraints.

Comparison: Tor Browser vs Hardened Firefox vs Mullvad Browser

Tor Browser strengths

  • Designed to make users look the same (uniform fingerprinting)
  • Blends users at the network level via the Tor decentralized network

Hardened Firefox (Arkenfox) strengths (and tradeoffs)

  • Strong privacy via hardening, but the speaker notes tradeoffs:
    • time/effort
    • usability sacrifices
    • potentially increased uniqueness affecting fingerprinting in some contexts

Mullvad Browser as a “middle ground”

Mullvad Browser aims for similar fingerprinting behavior to Tor while using a more usable hardened-Firefox-like approach.

  • Best case posture described: using Mullvad VPN with the browser
  • While Mullvad claims you can use the browser without VPN, the speaker emphasizes the ideal setup involves Mullvad VPN

Centralization Trust Tradeoff (VPN vs Tor)

The speaker highlights that Mullvad, as a VPN, is centralized, meaning users must trust the company.

  • This contrasts with Tor’s decentralized model.
  • The speaker argues Mullvad is one of the few VPNs with enough reputation/technology to make that trust more reasonable.

Community Measurement / Review Tooling

  • privacytests.org has already added Mullvad Browser for comparison tests.

Arkenfox “Cannibalization” Discussion

The speaker claims Arkenfox may be shutting down soon (or the maintainer may be moving in that direction) because Mullvad Browser provides much of the same value.

They also mention a post comparing Arkenfox vs Mullvad Browser from the Arkenfox maintainer (linked in the description per the speaker).

Threat-Model Recommendations: Disposable vs Account Browser

The speaker frames usage like this:

  • Mullvad Browser as a “disposable browser” for lower-identity browsing:
    • search
    • news
    • hobbies
    • watching content
  • For highly identity-linked actions (e.g., banking):
    • use a more conventional/account-focused browser

Speaker’s Personal Analysis

  • The speaker says they may use Mullvad Browser as a secondary browser for lower-threat general tasks
  • They state that Tor is too slow for day-to-day use
  • They do not intend to replace Tor completely; Tor remains for “particular situations” requiring maximum safety

Questions Raised / Uncertainties

Key questions the speaker raises include:

  • Why web authentication is disabled by default
  • If a user is not a Mullvad subscriber, what happens if they uninstall the Mullvad extension:
    • Would anonymity decrease?
    • Any downgrade in safety?
    • Should the extension be left installed for maximum protection?
  • Whether the ecosystem will expand, such as:
    • bookmark sync across devices
    • mobile clients
