Brave vs Firefox vs Tor: which privacy browser should you use?

Choose by threat, not by a "most secure" label. Brave, Firefox (configured) and Tor Browser are the three leading options, and each defends against different threats, with different trade-offs in speed, site compatibility and ease of use.

For daily browsing with strong privacy and no compromise on speed, choose Brave. For maximum customization and the strongest alternative outside the Chrome engine, choose Firefox with hardened settings. For maximum anonymity against ISP surveillance, fingerprinting and IP tracking, choose Tor Browser and accept the speed penalty. Most users benefit from running Brave for everyday tasks and Tor Browser separately for sensitive research.

Brave: privacy without the pain

Brave is a Chromium browser with strong privacy protections switched on by default. Its Shields block ads and trackers, and its fingerprint defence adds small random changes ("farbling") to canvas, WebGL and audio values in the default setting. The random values change per site and per session, which makes cross-site tracking via fingerprinting much harder.

  • HTTPS by default: since version 1.50 (2023) Brave tries HTTPS for every site and falls back to HTTP only when needed.
  • WebRTC leak protection: Brave's WebRTC setting can stop the browser from exposing local IP addresses; see our WebRTC leak guide.
  • Localhost permission: since version 1.54 (2023) public sites need permission to reach localhost, a defence against localhost tracking.

Brave uses Chrome extensions and offers Brave Sync between devices. Because it shares Chrome's engine, almost every site works.

Firefox (configured): the customizer's choice

Firefox is the only major browser that uses neither Google's Chromium engine nor Apple's WebKit. Its Gecko engine is independent of Google's infrastructure, and the browser is open-source software from Mozilla.

Firefox's strength is configurability. With the right settings and extensions it gets close to Tor Browser's fingerprint resistance while keeping compatibility with most websites. Key settings:

  1. Set Enhanced Tracking Protection to Strict. Mozilla says the fingerprinting defences in Firefox 145 cut the share of users seen as unique almost in half in Strict mode and Private Browsing.
  2. For stronger protection, enable privacy.resistFingerprinting in about:config. Expect some sites to break.
  3. Install uBlock Origin.
  4. Enable DNS over HTTPS. A DNS leak test shows whether it works.

Firefox Sync works across Windows, macOS, Linux, Android and iOS.

Tor Browser: maximum anonymity

Tor Browser provides the strongest available protection against IP tracking and fingerprinting. It routes traffic through three random relays of the Tor network and standardises browser signals, so its users look as alike as possible.

The trade-offs:

  • Speed: Tor is much slower than a normal connection. The old figure of "5–10× slower" is a rule of thumb, not a measurement; the Tor Project only says it "can sometimes be slower" because traffic passes volunteer relays around the world.
  • Blocking: websites can always detect Tor connections, and many sites block Tor exit nodes or show CAPTCHAs.
  • Features: some interactive features do not work reliably, especially at the "Safer" and "Safest" security levels.
  • Logins: signing in to an account identifies you, even over Tor.

Our Tor Browser privacy guide explains correct usage.

What about Chrome and a VPN?

Chrome blocks fewer trackers by default than Brave or Firefox in Strict mode. A VPN hides your IP address from websites but does not stop fingerprinting or trackers inside the browser.

How can you check your browser's privacy?

Run the SpeedIQ test in each browser: it checks your IP, DNS provider, WebRTC, IPv6 and Tor status, a Canvas hash and other fingerprint values, and keeps the results in your browser. Compare the Canvas hash in two sessions: in Brave it should change. More checks are listed in our online privacy check guide.

FAQ

Is Brave or Firefox better for privacy?

Brave is stronger out of the box. Firefox gets close with Strict tracking protection, uBlock Origin and hardened settings.

Does Brave hide my IP address?

No. Brave blocks trackers and randomises fingerprints, but websites still see your IP address unless you use a VPN or Tor.

Why is Tor Browser so slow?

Your traffic passes three volunteer relays around the world, and many users share the network, so latency is higher than on a direct connection.

Can I install uBlock Origin in Tor Browser?

The Tor Project strongly discourages extra add-ons, because they can make your Tor Browser fingerprint unique.
