If you have been comparing Mullvad Browser vs. Tor Browser, you are probably trying to figure out which one actually fits how you browse. Both are built to resist fingerprinting and surveillance, but they are not interchangeable, and picking the wrong one for your situation can leave gaps in your privacy. This guide breaks down what each browser does, where they overlap, and when each makes sense.
What the two browsers have in common
Mullvad Browser is developed by the Tor Project in collaboration with Mullvad VPN. It is, at its core, a version of Tor Browser with the Tor network integration removed. That shared origin matters: both browsers use the same anti-fingerprinting techniques.
The goal of that shared technology is to make your browser's fingerprint identical to every other user of the same browser. Fonts, rendered content, and several hardware APIs are deliberately masked so that tracking scripts cannot pick you out of the crowd. Both browsers also ship with private browsing enabled by default and block third-party trackers and cookies out of the box.
The core difference: how each one connects you to the internet
This is where the two diverge. Tor Browser routes your traffic through the Tor network, bouncing it through multiple volunteer-run relays before it reaches its destination. Mullvad Browser does not use the Tor network at all.
Instead, Mullvad Browser connects to the internet through a VPN, specifically Mullvad's encrypted tunnels, if you choose to pair it with Mullvad VPN. You can also use Mullvad Browser with no VPN, or with a different VPN provider you trust. According to the Tor Project's own FAQ, aside from this connection method, the differences between the two browsers are small and come down to individual preference and use case.
Why this connection difference actually matters
Because Mullvad Browser does not route through Tor, it loses certain Tor-specific protections. Tor's layered relay system is designed so that no single party, not even Mullvad, can see both who you are and what you are visiting at the same time.
A VPN, by contrast, is a single trusted party sitting between you and the internet. That party can, in principle, see your traffic unless you are relying on strict no-logs policies and technical safeguards. This is why the Tor Project is careful to say that if you pair Mullvad Browser with a VPN, you need to use a provider you genuinely trust.
Neither setup makes you automatically anonymous. Tor Browser does not either. Logging into a personal account, downloading and opening files, or reusing the same usernames across sessions can undermine anonymity no matter which browser or network you use.
When Tor Browser is the better choice
- You need to access onion services (.onion sites), which require the Tor network to resolve at all.
- Your threat model includes hiding your IP address and general location from the sites you visit and from your network provider.
- You want to avoid relying on any single company or VPN provider as a trusted intermediary.
- You are in a context where metadata about who you are talking to online could carry real risk.
The Tor Project notes that Mullvad Browser is best suited to the threat model of corporate mass surveillance by big tech, rather than the broader anonymity goals Tor Browser is built for. If your main concern is evading ad-tech tracking and fingerprinting rather than hiding your network identity, that distinction matters.
When Mullvad Browser is the better choice
- You want Tor Browser's anti-fingerprinting protections but need faster, more typical browsing speeds than the Tor network provides.
- You already use a VPN you trust and want a browser that pairs well with it.
- Your main concern is browser fingerprinting and tracking by advertisers and data brokers, not hiding your IP from every party involved.
- You do not need access to onion services.
Mullvad Browser does not require you to use Mullvad's VPN specifically. It is free, open-source, and distributed by Mullvad, but developed by the Tor Project, so the anti-fingerprinting engineering behind it is the same team's work either way.
A practical way to think about it
Treat Tor Browser as the tool for when the network path itself needs to be anonymized: to reach something like an onion service, or to resist your traffic being tied to your location. Treat Mullvad Browser as the tool for everyday browsing where you want strong resistance to fingerprinting without the latency of routing through Tor relays.
Some people use both, switching depending on the task. What matters more than the brand name is understanding what each setup actually protects against, and what it does not.
A caution on how you get either browser
Always download Tor Browser directly from the Tor Project's official site, and Mullvad Browser directly from Mullvad's official site. Avoid third-party download links or directory pages claiming to offer "faster" or "customized" versions.
This same caution applies if you later go looking for onion services to visit. A general-purpose link list, including the various pages calling themselves "the Hidden Wiki," is not a safe starting point. These pages are mostly unmoderated clones riddled with outdated, fake, or outright scam links. The safer approach is to get an onion address directly from an organization you already trust on the surface web, such as a news outlet or a privacy-focused service, and verify it against that organization's official site before using it.
