The 2026 Mullvad Browser Review

Mullvad Browser is a free, privacy-focused web browser developed by the Tor Project in partnership with Mullvad VPN. It is based on Mozilla Firefox ESR and designed to minimise tracking, fingerprinting, and surveillance—offering much of Tor Browser’s privacy technology, but intended for use with VPNs rather than the Tor network. Mullvad Browser is ideal for users who want robust privacy protections without the slower speeds or circuit isolation of Tor.

Key Features

Privacy by Default:
Mullvad Browser disables telemetry, analytics, and most forms of automatic data collection. It does not retain browsing history or cookies after sessions by default.
Open Source & Actively Maintained:
Developed by the Tor Project, with regular updates for privacy and security.

Privacy and Security

Fingerprinting Resistance:
- Letterboxing: Windows are rounded to fixed sizes with margins, reducing screen-size fingerprinting.
- User-Agent Spoofing: Standardises User-Agent strings to group users together and limit uniqueness.
- Canvas Blocking: Prevents extraction of identifying data from HTML5 canvas elements.
- First-Party Isolation: Keeps cookies and site data separate for each website, preventing cross-site tracking.
- Font and Language Limiting: Restricts font enumeration and language requests to reduce fingerprinting vectors.
NoScript Integration:
Blocks dangerous scripts and gives users control over JavaScript execution.
Search Privacy:
DuckDuckGo is the default search engine, offering privacy and no history logging. Onion services are not supported.

Limitations

No Built-in VPN:
Mullvad Browser is designed to be used alongside a VPN (such as Mullvad VPN), but does not include VPN functionality itself.
No Circuit Isolation:
Unlike Tor Browser, Mullvad Browser does not route traffic through the Tor network or isolate circuits per site. All browsing occurs over your VPN connection.

Compatibility and Availability

Mullvad Browser is available for Windows, macOS, and Linux. It is designed to be used with a trustworthy VPN, but can also be used independently, although using it with a VPN enhances privacy protections.

Pros and Cons

Pros

Strong privacy and anti-fingerprinting protections
No telemetry or analytics
First-party isolation and NoScript built-in
Easy to use with any VPN for improved privacy and speed
DuckDuckGo as default search engine
Open-source and regularly updated

Cons

Does not anonymise your IP address on its own (requires a VPN for network privacy)
No Tor network integration or circuit isolation
No access to .onion sites or censorship circumvention via Tor
Some strict privacy measures may affect site compatibility
Not suitable for users needing highest anonymity or censorship circumvention

Summary

Mullvad Browser is an excellent choice for users who want robust privacy, anti-fingerprinting, and tracking resistance, but prefer to use a VPN rather than the Tor network. It offers many of Tor Browser’s protections in a faster, more flexible package, but does not provide the same level of anonymity or access to onion services. Mullvad Browser is best for privacy-conscious users who value usability and speed alongside strong privacy features.
