The most private web browser: Brave, Firefox, Safari, DuckDuckGo, Tor and Chrome compared
For most people, Brave, Firefox and Safari all block cross-site tracking well out of the box; Tor Browser is the most private but slow and not for everyday use. Chrome is the least private by default, and a few settings matter more than which browser you choose.

Key takeaways
- Everyday privacy with no setup: Brave, which blocks ads, trackers and cross-site cookies on every site by default, according to Brave.
- Best open-source all-rounder: Firefox, with Enhanced Tracking Protection and Total Cookie Protection on by default.
- On iPhone and Mac: Safari is a sound choice; its tracking prevention is built in.
- Maximum anonymity: Tor Browser, at the cost of speed and some sites refusing to work.
- Chrome keeps third-party cookies after Google dropped its plan to phase them out in 2025, so it is the one to tighten or replace.
What a private browser can and cannot do
A browser decides how much the websites you visit, and the ad and analytics companies inside them, can learn and link together. The three big tracking techniques are cross-site cookies (a tracker recognizes you on every site that embeds it), fingerprinting (identifying you from your device's settings) and plain logging by the sites you sign in to.
A browser can block the first two well. It cannot stop a site you are logged in to, such as Google, Amazon or Facebook, from recording what you do there. It does not hide your IP address from websites or your internet provider (a VPN or Tor does that; see do I need a VPN?), and private or incognito mode only stops history being saved on your own device.
Six browsers compared
Default privacy protections, as each maker describes them
| Browser | Blocks cross-site trackers by default | Fingerprinting protection | Open source | Best for |
|---|---|---|---|---|
| Brave | Yes, ads and trackers (Shields) | Yes, randomizes or blocks identifying features | Yes | Strong privacy with no setup |
| Firefox | Yes, Enhanced Tracking Protection | Blocks known fingerprinters; more in Strict mode | Yes | An independent, open-source all-rounder |
| Safari | Yes, Intelligent Tracking Prevention | Some, built in | Engine only (WebKit) | iPhone, iPad and Mac users |
| DuckDuckGo | Yes, tracker blocking | Some | Partly | Simple privacy on phones, with a fire button |
| Tor Browser | Yes | Strongest: makes users look alike | Yes | Anonymity, hiding your IP address |
| Chrome | No, third-party cookies allowed by default | Limited | Engine only (Chromium) | Compatibility, if you change the settings |
Brave: the strongest defaults
Brave Shields are on for every site by default, according to Brave. They block third-party ads and trackers, block cross-site cookies, swap third-party storage for temporary storage that is deleted automatically, and randomize or remove the browser features trackers use to fingerprint you. Brave is built on Chromium, so Chrome extensions and sites that only work in Chrome work in Brave.
Two things to know. Brave has its own ad and rewards program and a crypto wallet; both are optional and you can switch them off. And if a site breaks, Shields can be turned down for that one site rather than everywhere.
Firefox and Safari: strong and mainstream
Firefox is made by the nonprofit-owned Mozilla and is the only major browser not built on Google's or Apple's engine. Its Enhanced Tracking Protection is on by default, and Total Cookie Protection gives each website its own cookie jar so a tracker cannot follow you from one site to the next. Switching Enhanced Tracking Protection to Strict blocks more, at the risk of breaking the odd site.
Safari has Intelligent Tracking Prevention built in and on by default, and Apple's Privacy Report shows which trackers it stopped on each site. On an iPhone every browser uses Apple's WebKit engine underneath, so Safari's protections are a reasonable baseline there. If you pay for iCloud+, Private Relay hides your IP address from websites when you browse in Safari.
DuckDuckGo and Tor Browser
The DuckDuckGo browser blocks trackers, defaults to DuckDuckGo search, and has a fire button that wipes tabs and data in one tap. It is a simple choice on a phone, particularly for someone who will never change a setting.
Tor Browser is in a different class. It sends your traffic through three volunteer relays so websites cannot see your IP address, and it is designed to make every user look the same to resist fingerprinting. It is the right tool for journalists, activists and anyone hiding from a capable adversary. For daily browsing it is slow, and many sites challenge or block Tor traffic.
Chrome: what changed, and how to tighten it
Google spent years saying it would phase third-party cookies out of Chrome. In 2025 it reversed course: Chrome keeps third-party cookies and its existing cookie controls, and Google wound down most of the "Privacy Sandbox" technologies meant to replace them. So Chrome still allows cross-site tracking cookies by default, unlike every other browser on this list.
If you stay on Chrome, change these:
- Settings, Privacy and security, Third-party cookies: choose Block third-party cookies.
- Settings, Privacy and security, Ad privacy: turn off each ad measurement and topics option.
- Visit your Google Account's My Activity and set Web and App Activity to auto-delete, or turn it off.
- Keep Safe Browsing on. It protects you from known phishing and malware sites.
Settings that matter more than the browser
- Fewer extensions. Every extension can read the pages it runs on. Remove any you do not use, and never install a "free VPN" extension from a company you cannot identify (VPN vs proxy explains why).
- Sign out of the browser, or at least turn off history sync, if you do not want your browsing tied to an account.
- Change the search engine to one that does not build a profile, such as DuckDuckGo, Brave Search or Startpage.
- Keep it updated. Browser updates fix security holes that are exploited in the wild; see keep your devices updated.
- Use a password manager rather than the browser's own if you switch browsers often; see the best password manager.
Free step
A browser cannot stop people-search sites publishing your address, and it cannot hide your IP address from the Wi-Fi network you are on. For those, a VPN helps on untrusted networks:

Common questions
What is the most private browser?
Tor Browser is the most private, because it hides your IP address and makes users look alike, but it is slow for daily use. For everyday browsing, Brave has the strongest defaults, and Firefox and Safari also block cross-site tracking out of the box.
Is Chrome private?
Less than the alternatives. In 2025 Google dropped its plan to phase out third-party cookies, so Chrome still allows cross-site tracking cookies by default. You can block them in Settings, Privacy and security, Third-party cookies.
Does incognito mode make me private?
No. Incognito or private mode stops your browsing history and cookies being saved on your own device after you close the window. Websites, your employer and your internet provider can still see your activity.
Is Brave safe to use?
Brave is open source and blocks ads, trackers and cross-site cookies on every site by default, according to Brave. Its rewards program and crypto wallet are optional and can be turned off.

- VPN vs proxy: what each one hides, and when a proxy is enoughProxies and VPNs both hide your IP address from websites. Only a VPN encrypts everything your device sends, and the difference matters most on networks you don't trust.
- NordVPN vs Proton VPN: which one should you pick?Both are mainstream VPNs with repeated independent no-logs audits. Pick Proton VPN if you want a genuinely free plan, open-source apps and a Swiss company; pick NordVPN if you want a paid all-rounder with lots of extras and do not need a free tier.
- Signal vs WhatsApp vs iMessage: which messaging app is most private?Signal, WhatsApp and iMessage all encrypt message content end to end by default. Signal is the most private because it keeps almost no metadata; WhatsApp and iMessage are private in transit but can leak through unencrypted cloud backups unless you change a setting.
