Test your browser

Test your browser before logging into sensitive sites!

If you're using a VPN, Proxy, or privacy-focused browser, it's not enough to just change your IP. Websites collect dozens of other information from your browser and device to assess its identity and credibility.
Two free and very useful tools for this:

 
BrowserScan
https://www.browserscan.net/

FV.Pro
https://fv.pro/

You can check the following with these two sites:

Browser Fingerprint (fingerprint of the browser)
IP, ISP, ASN and approximate location
Leakage WebRTC and DNS Leak
Canvas, WebGL, WebGPU and audio Fingerprint
User-Agent, language, Timezone and other browser information
Fingerprints from TLS, JA3 and JA4
Synchronization between IP, browser, operating system and other device specifications

One of the best features of these two sites is that if there is a discrepancy or suspicion between your information, they clearly specify it (in BrowserScan, usually in red). This way, you quickly understand what might be unusual from the point of view of security systems.
These tools are especially useful before using services that have anti-Fraud systems, such as:

Freelance sites
Twitch
Exchanges and financial services
Earning sites
Advertising platforms and other sensitive services

Important: if all tests are green, it does not mean that your account will be verified or will never be blocked. These tools only help you identify and address common leaks, inconsistencies, and problems before using these services.
