If you want one answer, it is Tor Browser. It is the only browser on this list that hides your IP address by itself, and it also tries to make your browser look like everyone else’s. Mullvad Browser goes after the fingerprint but leaves your IP address alone. Brave, Firefox, LibreWolf and the DuckDuckGo browser are tracking filters. Some are easy to live with every day, but in a normal window none of them hides your IP address from the sites you visit. Which one fits you depends on who you are trying to stay hidden from. Last checked: 11 November 2026.
| Browser | Hides your IP address | Fingerprinting | Best for | Main catch |
|---|---|---|---|---|
| Tor Browser | Yes. Sites see a Tor connection. | Tries to make users look alike | Staying anonymous | Slower than other browsers |
| Mullvad Browser | No. Pair it with a VPN. | Aims to give users similar fingerprints | Fingerprint defense without Tor | Desktop only |
| Brave | Only in its Tor private window | Blocks some APIs and randomizes others | Everyday use with built-in blocking | The Tor window can slow browsing |
| Firefox | No (Mozilla says so) | Blocks known fingerprinters by default | A familiar everyday browser | Not anonymous on its own |
| LibreWolf | No claim on its site | Says it strengthens protection | Firefox fans who want hardened defaults | Desktop only, as listed on its site |
| DuckDuckGo browser | No claim in the pages we read | Blocks listed fingerprinting scripts | Simple tracker blocking | Protections differ by platform |
This is general information, not legal or security advice. No browser can promise you will never be tracked, and the makers say so themselves.
Private window, privacy browser, anonymous browser
People use these three words as if they meant the same thing. They do not, and the mix-up is where most bad advice starts.
A private window is a cleanup tool. Mozilla says a Firefox Private Window removes history, cookies and site data when you close it, blocks known trackers, and keeps the bookmarks and downloads you made. Mozilla is also clear about the limits. A private window does not hide your IP address or your location, and it does not make you anonymous to sites, search engines, your internet provider or your employer.
A privacy browser goes further against tracking. It blocks trackers and tries to limit what a site can learn about your browser. That is useful. But your IP address still travels with every request, so the site, and anyone watching your connection, can still see it.
An anonymous browser tries to break the link between you and what you do. Of the six here, only Tor Browser does that by itself, because it also changes the address sites see. The others need a VPN or the Tor network added on top.
How we picked these browsers
We went to each browser’s own pages and read what the makers claim and what they admit. Four questions drove the list. Does it hide your IP address? What does it do about fingerprinting? Where does it run? And what does the maker say it cannot do?
We did not run lab tests for this page, so you will not find leak or fingerprint results here. Where something is our judgment, we say so. We also skipped the privacy scores some review sites hand out, because the ones we looked at do not explain how they work them out.
Why fingerprinting decides the ranking
Cookies are easy to clear. A fingerprint never sits on your device. A site reads details your browser hands over and builds a profile from them. The EFF’s Cover Your Tracks lists what it logs for this: user agent, HTTP Accept headers, screen resolution and color depth, time zone, plugins, fonts, JavaScript and cookie support, canvas and WebGL hashes, platform, language and touchscreen support. It compares your values with recent visitors and gives you a uniqueness score. You can see the first item on that list for your own browser with What Is My User Agent.
The EFF says a unique fingerprint can let a tracker pick you out without cookies, so clearing cookies does not help. That is why a browser that only blocks trackers is not the same as one that tries to hide you in a crowd.
There are two schools here. Tor Browser and Mullvad Browser try to make every user look the same. Brave goes the other way. Its own posts describe adding small random changes to some values, so each site and each session sees something different and cannot link you across them. Brave also says that people facing targeted attacks may be better served by Tor Browser. We like that it says so.
Neither school is perfect. The Tor Project says its browser does not make everyone identical, because some traits, like your operating system and language, are needed for the browser to work. Brave’s own write-up says that making users similar only works on sites that have lots of visitors like you, and that changing values can break sites. Fingerprint defense lowers the risk. It does not remove it.
The best anonymous browsers, one by one
Tor Browser: the most anonymous
Tor Browser is built on Firefox ESR and sends your traffic through the Tor network. The Tor Project says your internet provider, and anyone watching your local connection, cannot see the names or addresses of the sites you visit. A provider may still see that you are using Tor. The sites you visit see a connection from the Tor network instead of your real IP address, and they do not know who you are unless you tell them.
The fingerprint work is real too. The Tor Project says it rounds window sizes, reports a small set of standard platform labels, limits fonts and languages, and blocks canvas image extraction.
It has a slider worth knowing about. Tor Browser has three security levels. Standard is the default and leaves every feature on. Safer turns off website features that are often dangerous, so JavaScript stops working on sites without HTTPS, and audio and video become click-to-play. Safest allows only what static sites need and disables JavaScript by default on every site. The Tor Project warns that higher levels will break some pages. Android has the same three levels.
Now the limits. Sign in to a site and that site knows who you are. The Tor Project says that giving your name, email or any other personal detail ends your anonymity with that site. It also says it is not safe to use BitTorrent over Tor. Proton’s guide to Tor says Tor is slower than other browsers.
Our view: use Tor Browser for the task that needs it and keep a faster browser for everything else. The steps are in how to use tor safely.
Mullvad Browser: Tor-style fingerprint defense without the Tor network
Mullvad’s page says the Tor Project developed this browser at Mullvad’s request. It aims to give users similar fingerprints, using methods such as letterboxing, which adds grey bars around the page. It runs on Linux, macOS and Windows, and the page does not mention mobile.
Mullvad is blunt about your IP address. The browser does not hide it. A VPN does, and Mullvad recommends using one. You do not need Mullvad’s own VPN, and the browser is free with or without it.
It suits someone who wants the fingerprint protection without Tor’s slowdown and already trusts a VPN. If you use it without one, sites and your internet provider still see your real IP address. In that case you have a quieter browser, not an anonymous one.
Brave: built-in blocking for everyday use
Brave’s privacy page says its Shields block trackers, cross-site cookie tracking and fingerprinting, and that you can click the Shields icon to see what was blocked on a page. Its fingerprint defense is the randomizing kind described above. Brave’s own posts say this applies to things like canvas and audio, and later to language and fonts. The values are seeded per session and per site, so one site cannot match you to another.
Brave also has a private window with Tor. Brave says that window masks your IP address, and warns it can slow browsing.
Read that wording closely. Brave ties IP masking to the Tor window, not to normal browsing. In a normal window your IP address is visible, like in any other browser. Browser makers say what they intend. They do not promise you will never be identified.
It suits people who want blocking on from the first minute and rarely touch settings. For the head-to-head with the others, see tor browser vs mullvad browser vs brave.
LibreWolf: hardened Firefox for the desktop
LibreWolf calls itself an independent, modified version of Firefox. Its site says it strengthens protection against tracking and fingerprinting, removes telemetry and ships with uBlock Origin. It is built from the newest stable Firefox source and is not affiliated with Mozilla. Install guides cover Windows, macOS, OpenBSD and several Linux families. No mobile app appears on the site.
The site does not claim to hide your IP address, so treat LibreWolf as a privacy browser, not an anonymous one. It fits people who like Firefox and want stricter defaults without tuning settings by hand.
Firefox: the familiar choice
Firefox gives you more control than most mainstream browsers, but you have to switch it on. Mozilla says Enhanced Tracking Protection has three levels. Standard is the default. It blocks social media trackers, fingerprinters and cryptominers on all sites, and blocks cross-site tracking cookies, but it blocks tracking content only in Private Windows. Strict blocks all cross-site cookies and tracking content in every window. Custom lets you pick.
Mozilla warns that Strict can break sites, because trackers sometimes sit inside content a site needs. The affected content can include login fields, forms, payments, comments and videos. On fingerprinting, Mozilla says Firefox blocks scripts from known fingerprinting companies by default. In Private Browsing it also limits the device details it shows to sites, and Strict turns both layers on.
Mozilla’s limits apply here as well. A Private Window does not hide your IP address, does not make you anonymous and does not stop a site recognizing you after you sign in. It blocks known trackers, not every tracker, and not ads.
Our view: turn on Strict, expect to fix the odd broken site, and think of Firefox as a good filter, not a way to hide. If you stay on it, see browse anonymously in firefox.
DuckDuckGo browser: simple tracker blocking
DuckDuckGo’s help page lists a long set of protections: third-party tracker loading, third-party and first-party cookies, CNAME cloaking, fingerprinting, HTTPS upgrading, link and referrer tracking, embedded social media content, Google AMP links and more. The same page shows that the list is not the same everywhere. For example, referrer tracking protection is listed as unsupported on Android, and embedded social media protection as unsupported on iOS and Android.
On fingerprinting, DuckDuckGo says its protection blocks listed fingerprinting scripts and overrides listed browser APIs. On Android, the API overrides do not apply in iframes. DuckDuckGo says no one can eliminate all hidden tracking or all profiling online. Its page mentions IP addresses only to explain that cookie-only protections leave them exposed, and that its tracker loading protection aims to stop tracking requests from loading in the first place. We found no statement that the browser hides your IP address from the sites you visit.
It suits beginners who want protection on from the start with nothing to configure.
Anonymous browsers on your phone
Mobile is where the list gets thin. The Tor Project’s download page lists Tor Browser for Android. For iPhone, the Tor Project recommends two apps, Onion Browser and Orbot. It also says Apple requires browsers on iOS to use WebKit, and that this stops Onion Browser from having the same privacy protections as Tor Browser. So an iPhone with Tor is not the same as a desktop with Tor.
Mullvad Browser is desktop only, and LibreWolf lists no mobile app. DuckDuckGo’s fingerprinting protection covers iOS and Android as well as desktop. Brave says its iOS version is built on WKWebView because Apple does not let it use its own rendering engine.
Safari, Edge and Opera: why they are not on the list
These three are popular, so readers ask about them. None is built to make you anonymous, but each has features worth knowing. This section relies on vendor documentation and press reports, not on our own tests.
Safari
Safari is the strongest of the three on fingerprinting. Starting with iOS 26 and macOS 26, Apple turned on Advanced Fingerprinting Protection for all browsing, where before it covered only Private Browsing. It makes your device data less unique to websites. It does not hide your IP address, and Safari has no network layer like Tor. According to 9to5Mac, Link Tracking Protection, which strips known tracking parameters from URLs, still applies by default only in Private Browsing and to links opened from Mail and Messages. Safari runs only on Apple devices. It is a sensible everyday browser on an iPhone or Mac, not an anonymous one.
Microsoft Edge
Edge offers three tracking prevention levels: Basic, Balanced and Strict. Balanced is the default, and Strict blocks more trackers but can break some sites. InPrivate removes local history, cookies and site data once all private windows close. Website tracking still follows your tracking prevention level, which in an InPrivate window matches your normal setting unless you choose Strict. Microsoft also lets Edge send optional diagnostic data, which you can switch off under Settings, then Privacy, search, and services. Windows Report says Microsoft is simplifying how InPrivate follows the main setting, so check the wording in your own version.
Opera
Opera’s free built-in “VPN” is a browser proxy, not a full VPN. ProPrivacy and Help Net Security both describe it that way. It covers only traffic inside the browser, so other apps on your device are not protected. Opera sells a separate paid service, Opera VPN Pro, which VPNOverview describes as a real VPN. In our view, a proxy only changes the IP address sites see. It does not reduce fingerprinting, and you trust Opera’s servers with your traffic. We would not use it as an anonymity tool.
The short version: for anonymity, pick from the browsers above. Safari and Edge are fine for everyday privacy if you tune their settings.
Which one should you use?
| Your situation | Use | Why |
|---|---|---|
| You need your activity unlinked from you | Tor Browser | It is the only one here that hides your IP address by itself (Tor Project). |
| You want fingerprint defense and already use a VPN | Mullvad Browser plus your VPN | Mullvad fights fingerprinting but does not hide your IP address. |
| You want blocking with little setup | Brave or the DuckDuckGo browser | Both turn tracker protections on for you. |
| You prefer Firefox | Firefox in Strict mode, or LibreWolf | Mozilla documents Strict mode. LibreWolf ships stricter defaults. |
| Your safety depends on not being identified | More than a browser | Our judgment: this needs a plan built around your real risk. |
If most people asked us for one setup, we would say two browsers. Use something comfortable for daily life, and keep Tor Browser for the moments you need it. Trying to do everything in one browser usually ends with you loosening the settings that mattered. That is our opinion, not a finding.
If you live in Chrome, you can still improve things. See browse anonymously in chrome. Edge and Opera are covered in private browsing in edge and opera. Antidetect browsers are a different category, and we cover them in their own guide.
Check what your browser reveals
We have not run these tests for you, so we give no results. You can run them in a few minutes. Do it in each browser you use, so you can compare.
- Open the EFF’s Cover Your Tracks. The EFF says it checks how well your tracker blockers work and how unique your browser is. It also warns that passing the blocker tests does not fully protect you if your fingerprint is unique.
- Run the Browser Fingerprint Test and compare the result across browsers.
- If you use a VPN, open What Is My IP Address and see whether your real address shows. Then run the DNS Leak Test and the IPv6 Leak Test. Mullvad Browser and Firefox do not hide your IP address, so a VPN is what changes it.
- For a wider view, run the Privacy Score Checker.
Check your own browser for leaks
Open the tool in each browser you use and see what your connection gives away.
Run the WebRTC Leak TestMistakes that undo any browser
- Signing in. Mozilla says signing in identifies you to that site, and the Tor Project says the same for Tor Browser.
- Giving personal details. The Tor Project says a name, email or address ends your anonymity with that site.
- Using BitTorrent over Tor. The Tor Project says this is not safe.
- Assuming a private window hides your IP address. Mozilla says it does not.
- Changing settings until you stand out. The Tor Project says its protections work by limiting how much users vary, so we would leave the defaults alone unless you know why you are changing them.

Frequently asked questions
What is the most anonymous browser?
Tor Browser. The Tor Project says your internet provider cannot see which sites you visit, and sites see a Tor connection instead of your real IP address.
Does Mullvad Browser hide my IP address?
No. Mullvad says the browser does not hide your IP address and recommends using a VPN with it.
Is Brave anonymous?
Not in a normal window. Brave’s Shields block trackers and fingerprinting, and its private window with Tor masks your IP address. Brave warns that the Tor window can slow browsing.
Is Firefox private enough?
It is a strong tracking filter if you turn on Strict mode. Mozilla says a Private Window does not hide your IP address and does not make you anonymous.
Do I need a VPN with an anonymous browser?
It depends on the browser. Tor Browser hides your IP address on its own. Mullvad Browser does not, and Mullvad recommends a VPN. Firefox and the others here do not hide it either in a normal window.
Can a browser make me fully anonymous?
No. The Tor Project says signing in or giving personal details ends your anonymity with that site, and DuckDuckGo says no one can eliminate all hidden tracking.
Is there a Tor Browser for iPhone?
The Tor Project recommends Onion Browser and Orbot for iPhone, and says Apple’s WebKit rule stops Onion Browser from matching the protections of Tor Browser. Tor Browser itself is listed for desktop and Android.
What does Tor Browser’s Safer level do?
The Tor Project says it turns off website features that are often dangerous. JavaScript stops working on sites without HTTPS, and audio and video become click-to-play. Some sites may lose functionality.
What we checked and what we could not confirm
We read pages from the Tor Project, Mullvad, Brave, Mozilla, LibreWolf, DuckDuckGo and the EFF, plus Proton’s guide to Tor. We also read several competing browser lists to see what they cover. We did not reuse their wording or their scores.
We could not confirm a few things. Some Tor Project statements, including what your internet provider can see and the BitTorrent warning, and the iPhone guidance and security levels, came from search excerpts of its support pages, not full page reads. We did not read Brave’s current privacy settings page for fingerprinting details, so that section relies on Brave’s own blog posts, some of which may be older than the browser you run. We could not confirm that DuckDuckGo’s browser hides your IP address and found nothing saying it does. We ran no tests of our own for this page.
