How to Test WebRTC Leaks: Best Method (Online vs. Extension)

Many people worry that their real IP location, browser fingerprint, and other privacy data may be exposed when browsing the internet, especially frequent users of IP tools.

Currently, mainstream methods for checking such risks fall into two categories: Online WebRTC Leak Detection and Browser Extension-Based Detection Tools.

Next, let’s take a detailed look at: Online WebRTC Leak Detection vs. Browser Extensions — Which Is More Reliable?

1. Why Is WebRTC Leakage So Troubling?

WebRTC is a built-in browser technology for real-time communication. Sometimes, even if you’re using an IP masking tool, it may still expose your real IP address through STUN servers.

This means your privacy may be tracked by websites, anonymity may be weakened, and certain region-sensitive browsing could pose risks.

Therefore, many users rely on WebRTC leak detection tools to check whether their real IP is being exposed.

2. Online WebRTC Leak Detection : Fast and Convenient, but Limited

Advantages of Online Detection:

① No installation required
Just open the webpage to run the check — extremely beginner-friendly.

② Clear results
It usually tells you directly whether your real IP is exposed.

③ Ideal for quick checks
For example, after switching VPN servers or clearing browser cache, you can re-test immediately.

But it has obvious drawbacks:

① Most sites only test WebRTC leaks
They do not cover browser fingerprinting, Canvas fingerprinting, audio fingerprinting, and many other privacy components.

② Accuracy depends on the site’s implementation
Different sites may produce different detection results.

③ No continuous monitoring
You need to manually visit the page; it cannot provide long-term protection.

3. Browser Extensions: More Comprehensive, but Not Perfect

Another option is using browser extensions to detect — and even block — WebRTC leaks.

Advantages:

① Real-time protection
Extensions can block WebRTC at the browser layer, making it more reliable than after-the-fact detection.

② More features
Some extensions can show IP info, change user agents, block scripts, etc. — almost like a mini privacy toolbox.

③ Supports automation
No need to manually check each time.

Problems:

① Quality varies widely
Some extensions simply wrap basic code and provide unstable protection.

② May break website functionality
Blocking WebRTC can disrupt video calls, online customer service, and other interactive features.

③ Cannot address other privacy risks
Many cannot detect browser fingerprinting, Canvas fingerprinting, firewall traversal, etc.

Browser extensions are more like “patches” than a full solution.

4. True Privacy Detection Must Cover the “Fingerprint Layer”

Relying solely on WebRTC detection or extensions cannot solve the root causes of privacy leakage.

Modern websites heavily rely on browser fingerprinting to track users. This method is harder to avoid and much more accurate.

If you care about your overall anonymity, you need more comprehensive detection tools.

5. Why Are More Users Choosing ToDetect Fingerprint Detection Tools ?

Compared to simple WebRTC detection, it offers broader coverage and shows your browser’s real exposure level.

It can also compare different browser configurations — for example, whether Chrome, Firefox, or Edge’s privacy mode is effective, or whether installed extensions improve privacy exposure.

6. So Which Method Is More Reliable?

1. If you just want to know whether there’s a WebRTC leak → Online detection is enough

Fast, convenient, and meets basic needs.

2. If you want to prevent leaks proactively → Browser extensions are more useful

They offer real-time blocking, but you must choose a reliable one.

3. If you want a full understanding of your browser’s privacy exposure → ToDetect is the better choice

Especially for users needing fingerprint recognition, IP leak analysis, and device characteristic detection.

Therefore, “which is more reliable” is not a simple either-or question — it depends on what problem you're trying to solve.

Conclusion

WebRTC leakage is only a small part of privacy exposure. Browser fingerprinting is more stealthy, harder to prevent, and more precise in tracking.

To truly improve online security, relying solely on extensions or single-point detection is not enough — you should combine detection + blocking + protection.

Privacy security is not achieved overnight; it is a continuous optimization process. It’s recommended to regularly use the ToDetect Fingerprint Detection Tool for comprehensive checks.
