🛡️ Not all browsers are created equal — especially when it comes to online privacy.
Most users think a VPN is enough. It’s not.
Browsers can leak your real IP, device fingerprint, and other metadata — even with a VPN enabled.
🧪 What We Tested
At WhoerIP.com, we ran controlled browser tests to check for:
- WebRTC leaks (IP exposure)
- Canvas fingerprinting
- Tracker blocking
- Default privacy configuration
🌐 Browsers in the Test
We tested the following browsers on Ubuntu 22.04 and Windows 11 behind a VPN (WireGuard):
- Google Chrome (stable)
- Mozilla Firefox (default + hardened)
- Brave (out of the box)
- LibreWolf (a hardened Firefox fork)
- Tor Browser
📊 Test Results
Browser | WebRTC Leak | Fingerprint Score | Tracker Blocking | Verdict |
---|---|---|---|---|
Tor | ❌ No | 🔒 Very Low | ✅ Yes | 🔥 Best privacy |
Brave | ❌ No | 🔒 Low | ✅ Yes | 👍 Recommended |
Firefox | ⚠️ Maybe* | ⚠️ Medium | ⚠️ Partial | 🛠 Needs tuning |
LibreWolf | ❌ No | 🔒 Very Low | ✅ Yes | 💪 Excellent |
Chrome | ✅ Yes | 😱 High | ❌ None | 🚨 Avoid for privacy |
* Firefox needs manual configuration to block WebRTC and fingerprinting.
🛠️ How to Harden Firefox
If you prefer Firefox, here are two must-change settings:
1. Disable WebRTC
Open about:config
and set:
media.peerconnection.enabled = false
2. Enable Anti-Fingerprinting
privacy.resistFingerprinting = true
Or just use LibreWolf — it’s Firefox with better defaults.

- DNS leaks
- WebRTC exposure
- Canvas, fonts, language fingerprinting
No installs, no registration, works in any browser.
💬 Conclusion
There is no single perfect browser, but some are far better than others:
- 🥇 Tor for maximum anonymity
- 🥈 LibreWolf and Brave for everyday privacy
- ❌ Chrome if you value your data — just don’t

It goes far beyond "use Brave or Tor" advice.
In this article, we break down real privacy and security features by category:
🔐 1. Data Isolation & Anti-Tracking
- Blocking third-party cookies and trackers
- Partitioning or isolating storage (cookies, localStorage, cache, IndexedDB)
- Blocking ad and analytics scripts
🔒 2. Secure Connections
- Enforcing HTTPS connections
- Warning about insecure (HTTP) sites
- Preventing IP address leaks
🕵️ 3. Fingerprinting Protection
- Hiding unique device/browser parameters
- Restricting access to system fonts, screen size, and other identifying APIs
🧹 4. Data Cleanup
- Automatically deleting history, cookies, and site data after each session
- Private/incognito browsing modes
✂️ 5. Stripping Tracking Parameters
- Removing tracking tags like
gclid
,fbclid
,utm_*
, and others from URLs
✅ Bottom line
A secure browser should:
- Block trackers
- Isolate site data
- Enforce HTTPS
- Resist fingerprinting
- Clean up your traces automatically
