Brave vs Firefox: Built-In Ad Blocking or Free VPN?

Pick Brave if you want ads, trackers and cookie pop-ups blocked the moment you install it, with no add-ons to set up, and you are happy on a Chromium-based browser that runs Chrome extensions. Pick Firefox if you want a browser that is not built on Chromium, a free built-in VPN, and a large add-on library that lets you choose your own ad blocker.

Both browsers are free, both run on Windows, macOS, Linux, Android and iOS, and both block trackers by default. The differences are in the engine underneath, how much is blocked out of the box, and what each one charges for.

Brave vs Firefox at a glance

Is Brave or Firefox better for privacy?

Both are strong, but Brave blocks more by default and Firefox gives you more to tune.

Brave turns on its Shields as soon as you start it. Its site says Brave blocks third-party ads on every website, blocks "Accept cookies?" pop-ups, protects against tracking and fingerprinting, and has Global Privacy Control switched on by default. It also offers private windows that route traffic through Tor, though Brave warns these can be slower.

Firefox blocks trackers automatically and uses Total Cookie Protection, which stops cookies from following you from one site to another. Its tracking protection has three levels: Standard, Strict (blocks more trackers and cookies, but some sites may need adjustments) and Custom, where you choose exactly what to block. Mozilla's homepage also states: "We don't sell your personal data and we never will."

The real gap is ads. Brave blocks them on its own. Firefox's own ad blocker guide points you to ad-blocking add-ons, so you install one yourself.

Does Brave or Firefox have a free VPN?

Firefox does, Brave does not.

We checked both VPN pages on 6 November 2026. Firefox's page described a free built-in VPN that hides your IP address, with 50 GB of protected browsing every month, a choice of browsing locations in more than 20 countries, and a banner saying data is unlimited through January 2027. You can turn it on for some sites and leave it off for others. Brave's Firewall + VPN is a subscription: $9.99 a month or $99.99 a year, with a 7-day free trial. Brave's VPN protects your whole device, not just the browser, which the Firefox VPN does not claim to do.

If you only want your IP hidden while browsing on café or hotel Wi-Fi, Firefox's free VPN covers it. If you want every app on your phone or laptop protected, Brave's paid VPN (or a separate VPN app) is the option.

Can I use Chrome extensions in Brave and Firefox?

In Brave, yes. In Firefox, no, it has its own add-on store.

Brave is built on Chromium, the same open source core as Google Chrome. Brave's help center says it supports nearly all Chromium-compatible extensions, which you install straight from the Chrome Web Store. Brave has also committed to keep supporting some older Manifest V2 extensions, specifically AdGuard, NoScript, uBlock Origin and uMatrix.

Firefox runs on Gecko, Mozilla's own rendering engine, and lists over 30,000 extensions in its own add-on library. Most popular tools, such as password managers and ad blockers, have Firefox versions. If one Chrome-only extension is essential to your work, check that it exists for Firefox before switching.

Is Brave really free, and what does Brave Rewards do?

Yes, the browser is free. Brave's FAQ says "Brave is completely free to use."

Brave does have optional paid and earning features, and this is where it feels busier than Firefox:

• Brave Rewards: an opt-in program where you can view Brave's own privacy-preserving ads and earn BAT (Basic Attention Token), a digital asset you can keep or use to tip publishers.
• Firewall + VPN: the paid VPN described above.
• Brave Origin: a stripped-down version of the browser that removes features such as Leo (Brave's AI assistant), News, Rewards, VPN and Wallet. It costs $59.99 as a one-time purchase, and it is free on Linux. Brave says the regular browser stays free and you can still hide unwanted features in it.

Firefox has no crypto token or rewards program. Its homepage says AI features are optional and can be turned off entirely.

Which runs on more devices?

It is a tie. Brave offers downloads for Android, iOS, Linux, macOS and Windows. Firefox's site offers Windows, macOS, Linux, Android and iOS, with tab, history and password sync between them.

One detail for older PCs: Firefox's site says the current Firefox is no longer supported on Windows 8.1 and below or on macOS 10.14 and below, and offers Firefox ESR (Extended Support Release) for those systems instead.

If neither fits, for example you want Tor-level anonymity, see our list of Tor Browser alternatives, which also covers Mullvad Browser and LibreWolf.

Which should you choose?

• You want ads and cookie banners gone with no setup: Brave.
• You rely on Chrome extensions: Brave, since it installs them from the Chrome Web Store.
• You want a free VPN inside the browser: Firefox.
• You want a browser that is not based on Chromium: Firefox, which uses Mozilla's Gecko engine.
• You want no crypto or rewards features at all: Firefox, or Brave Origin if you prefer Brave's blocking.
