Stop Trackers Dead: The Best Private Browsers for 2024 (2024)

Recommended by Our Editors

Avast is one of the few browsers included here with built-in VPN functionality, but using it will cost you $5.99 per month, with discounts if you sign up for a longer commitment. Avast tells you that its VPN uses the open-source, industry-standard OpenVPN protocol. A one-week free trial does not require payment info, though Avast has offered free services before with questionable nonmonetary costs.

The Avast Secure browser also features built-in ad blocking, anti-phishing features, and a password manager. Avast gives you tracker-in-chief Google Search as its default search engine, but the EFF’s Cover Your Tracks tool reports strong tracking protection though with a unique (traceable) fingerprinting profile. The Chromium-based browser looks good and is compatible with most sites.

Brave is a browser with an emphasis on privacy and ad-blocking, but at the same time, it lets you earn cryptocurrency while you browse. Like the majority of browsers these days, Brave relies on a customized version of Chromium, the code that powers Google Chrome, meaning it’s compatible with most websites. Brave has higher goals than simply letting you hoard crypto or even protecting your privacy. Its creators want to achieve a revolution in the way web commerce works, with direct micropayments taking the place of rampant ads. To earn cryptocurrency rewards with Brave, the software periodically pops up an unobtrusive ad in a box outside the browser window—you can turn it off if you prefer.

The EFF’s Cover Your Tracks tool reports “strong protection against Web tracking.” A feature called Shields blocks third-party tracking cookies and ads by default. Brave forces the more secure HTTPS (something common among recent browsers) and lets you choose between Standard and Aggressive tracker-blocking and ad-blocking. Brave also has advanced fingerprinting protections that “randomize the output of semi-identifying browser features” and turn off features commonly used to sniff device info. In our brief tests, Brave and Tempest were the only browsers for which the EFF tool reported a randomized fingerprint. Brave has other security-minded products, such as a search engine, a private messaging app, and an initiative called SugarCoat, designed to thwart scripts that gather your browsing data while maintaining site functionality.

The famed private search provider DuckDuckGo now has a standalone desktop app (still designated as beta) as well as a mobile web browser app. The Chromium-based browser boasts some design niceties. For example, a flame button at the top, sort of a panic button, lets you close tabs and delete browsing data instantly. The search bar is centered and on the same line as the back and forward navigation buttons, which look clean and clear. The new-tab page offers custom site buttons and a list of previous sites visited with a count of how many trackers were found and blocked for each.

The browser also includes automatic cookie consent management for popups and support for the Global Privacy Control emerging standard. It has Duck Player for playing YouTube videos without Google ads, which worked well in testing and could be reason enough to install the DuckDuckGo web browser!

You can also install the DuckDuckGo Privacy Essentials extension in your existing desktop browser to make it more private. It blocks third-party trackers, switches your search engine to its privacy-focused one, forces sites to use an encrypted HTTPS connection where available, and lets you see a privacy score for sites you visit. The extension raised Chrome’s score on the EFF’s Cover Your Tracks tool to "strong protection," which was also the score for the standalone DDG browser.

Platforms: Android, iOS, extension for Chrome, Windows

Like Avast and Opera, Epic Privacy Browser includes built-in VPN-like functionality with its encrypted proxy, which hides your IP address from the web at large. The company claims that Epic blocks ads, trackers, cryptomining, and even ultrasound signaling! It also blocks fingerprint tracking scripts and prevents WebRTC.

The EFF’s Cover Your Tracks tool reports only partial protection against tracking ads and invisible trackers in Epic with default settings, however. You see the same result that you get with Google Chrome: “Our tests indicate that you have some protection against Web tracking, but it has some gaps.” When you tap Epic’s umbrella button to enable the built-in version of uBlock, the results improve to "strong protection" against web tracking.

The browser's interface looks almost identical to that of Chrome, aside from the included privacy and proxy extension buttons. Otherwise, it lacks special convenience features found in competitors like Edge and Opera.

Ghostery Private Browser is based on the Firefox open source, modified to include the well-known Ghostery tracker-blocking extension. It's a free download for Android, Windows, iOS, and macOS. It also defaults to using Ghostery's own private search site, which uniquely indicates the amount of tracking and ads of result links. The company offers Ghostery Privacy Suite and maintains a database of trackers at WhoTracks.Me.

For me, the browser loads faster than Firefox, and uses a pleasant minimalist desing. It didn't, however, fare so well on the EFF's Cover Your Tracks test, which reported "some protection against Web tracking, but it has some gaps." This is actually a worse result than what I got for Edge and Firefox, but equal to Safari's. Ghostery Private browser doesn't appear on the PrivacyTests.org open-source tests of web browser privacy, but Firefox, on which Ghostery is built, does well on that.

Mozilla has long been at the forefront of trying to improve privacy on the web. Its Firefox browser is a free and open-source alternative to other browsers. The company came up with the Do Not Track option for browsers, which Google swiftly rendered useless by discouraging its use in market-leading Chrome; that only makes sense for the company that bases much of its business on tracking users. Firefox was the first browser with a private browsing mode that could hide browsing not only from people with access to your device, but also from other sites.

Firefox’s Enhanced Tracking Protection’s Standard setting blocks social media trackers, cross-site tracking cookies, cross-site cookies in Private Windows, tracking content in Private Windows, cryptominers, and fingerprinters. The EFF’s Cover Your Tracks tool reports “strong protection against Web tracking” at this setting. Strict mode blocks trackers hidden in ads, videos, and other site content. The fingerprinting protection currently uses a list of known fingerprint trackers, but Mozilla is working on a future update that will make your browser look more undistinguishable to thwart fingerprinters.

Unlike most of the other browsers here, Mullvad Browser is built on top of Mozilla's open-source Firefox code base. The browser was created in collaboration between the Mullvad VPN service and the Tor project, and it looks just like the Tor browser, only it doesn't offer actual Tor functionality (unlike the Brave browser).

In Mullvad's leak test, its browser beats most others in that it reports no DNS or WebRTC leaks. The browser comes with the excellent uBlock Origin ad- and tracker-blocking extension. And the default search provider is DuckDuckGo, which is better for privacy than Google or Bing, which other browsers default to. The Mullvad browser does push you toward signing up for the company's Mullvad VPN service, but at least it's a PCMag Editors' Choice winner. The browser, however, doesn't appear to have strong fingerprinting protection, showing a unique fingerprint visible to trackers according to the EFF's Cover Your Tracks test.

Opera has a long history of innovation among web browsers. The Norwegian software company was the first to include tabs and integrated search in a web browser, and an Opera developer invented CSS, just for starters. Now Opera has free built-in VPN, and the company offers a gaming browser called Opera GX. The latest version is the spiffy Opera One, which adds tile-like tab management, an AI chat sidebar, and a multithreaded compositor for faster rendering.

PCMag’s VPN experts always correct me when I mention that Opera has a built-in VPN, saying it should be called a Proxy, not a VPN. The distinction is that a standard VPN cloaks your IP address from all the traffic from your computer, while Opera’s feature only applies to the browser. Opera states that it’s a no-logging VPN, which is something you should look for when choosing any VPN. It uses AES-256 encryption.

Opera also blocks ads and trackers by default, and the EFF's Cover Your Tracks test reports "strong protection against Web tracking." It doesn’t have specific anti-fingerprinting features, so that same test says it presents a unique fingerprint, though with the VPN/proxy feature enabled that changes to "a nearly unique fingerprint," which is a win. With its Speed Dial and sidebar of quick-access buttons to things like messaging services and frequently visited sites, Opera still stands apart from most browsers in offering some unique conveniences.

Platforms: Android, iOS, macOS, Windows

Tempest is a recent Chromium-based browser that comes from a maker of a private search engine of the same name. It's pretty much Chrome with some privacy added. The home page is set to the Tempest search, which defaults to sending anonymous usage data and to auto-completing suggestions.

You can add site buttons, but annoyingly you can't change the startup page. I appreciate that it offers to encrypt search terms and show privacy reports for found sites. You have three levels of privacy in Settings to choose from: No Blocking, Block Trackers (the default), and Block Ads and Trackers. That's more than you get in Chrome, to be sure.

The browser defaults to using the Cloudflare DNS server, which is better than using the one provided by your ISP. The Security settings only offer Standard Protection or none; not Chrome's Enhance Protection, probably because the latter sends browsing data to Google.

On the EFF's Cover Your Tracks test, the browser was the only one besides Brave that reported a randomized fingerprint, which is encouraging. It only gets Partial credit for ad and tracker protection, however, even with Block Ads and Trackers selected in Settings. We'd be remiss not to mention that the software's founder, Michael Levit, has a track record of selling previous services to Chinese outfits, but he's taken the Founders' Pledge and committed to donating half the proceeds of Tempest to climate change efforts.

The Tor (it stands for the onion router) browser’s slogan is, “Protect yourself against tracking, surveillance, and censorship.” It’s the ultimate in privacy protection in a browser, and the EFF’s privacy test reports “strong protection against Web tracking.” It provides a multistep encrypted route for your browsing that makes identifying you very difficult. It provides even more privacy than a VPN because your encrypted traffic goes through at least three nodes. The first node knows the source but not the destination of the traffic, the middle ones know neither, and the last only knows only the destination. This system makes it nearly impossible to trace traffic back to you. The downside? It slows down your browsing.

If you crank up Tor to its safest level of protection and disable JavaScript, a lot of common sites won’t run—basically anything that features interactive content, such as YouTube. Tor lets you access sites that use its own onion protocol that’s separate from the standard web, often called the dark web, in addition to providing privacy and access to the standard web. The EFF's Cover Your Tracks tool reports "strong protection against Web tracking" but that "your browser has a unique fingerprint." Changing the browser's privacy setting to Safest results in top protection for fingerprinting. That said, there's not much you can do on the web at that setting, since it disables JavaScript.

An even more private way to run Tor is through Tails, a lightweight operating system based on Ubuntu that you run off a USB drive. Tails doesn’t save any unencrypted data from your browsing session and leaves no traces on your computer’s drive.

Vivaldi, an offshoot of Opera that also uses the Chromium browser code, is the ultimate in customizability among browsers. It includes innovative features like built-in translation, split-window view, tab groups, notes, a link sidebar, and mouse gesture support. It now features Workspaces, which let you group related browsing sessions.

Vivaldi includes built-in ad blocking and tracker blocking, though it doesn’t specifically attempt to thwart fingerprinters. As with the rest of the browser’s features, privacy settings are deep, broad, and granular, as you can see in the screenshot above. The EFF’s Cover Your Tracks test reported “strong protection against Web tracking” for Vivaldi with tracking protection on, though it still reported a unique fingerprint.

Waterfox is one of only a few browsers based on Mozilla's Gecko web rendering engine, the same one that powers Firefox. The organization behind Waterfox recently became independent of its corporate owner, so it's now an open-source project. The browser's docs include a clear, reassuring privacy policy, and it uses the same Enhanced Tracking Protection as Firefox. The browser site claims that "unless you specifically register for a web service with us, we do not want or touch your personal data."The tracking protection in Waterfox is identical to that in Firefox, which claims to protect against social media trackers, cross-site tracking cookies, fingerprinters, crypto miners, and trackers hidden in ads, videos, and other content. For a bit of added privacy, you can turn off WebRTC.

Like Firefox, Waterfox lets you sync bookmarks, history, tabs, passwords, add-ons, and settings. The browser uses Oblivious DNS, which obscures your website requests from your ISP, a boon to privacy. You can also use any extensions and themes designed for Firefox. The EFF's Cover Your Tracks test reports some protection against tracking with Waterfox's default privacy setting, but switching that to Strict gets a Strong protection result from the test. With either setting, the test reports a unique fingerprint, despite the browser's claim to fingerprinting protection, which, like most of the browsers here, only uses a block list rather than randomizing fingerprint data the way Brave does.
