Browser Fingerprint Test

What is Browser Fingerprinting?

Browser fingerprinting is a technique used by websites and advertisers to identify and track users without cookies. By combining dozens of data points — your browser version, screen resolution, installed fonts, graphics card, and more — websites can create a unique "fingerprint" that identifies you across sessions, even in private/incognito mode.

Why is it Concerning?

Unlike cookies, fingerprinting cannot be blocked by simply clearing your browser data. It operates silently in the background, requiring no consent, and is extremely difficult to prevent. Studies show that over 90% of browsers have a unique fingerprint.

What Data is Used?

• Canvas fingerprint — Browsers render graphics slightly differently based on GPU, drivers, and OS. This creates a unique pixel pattern.
• WebGL — Your graphics card vendor and renderer are exposed through WebGL APIs.
• Fonts — The set of fonts installed on your system can be detected by measuring text rendering dimensions.
• Audio fingerprint — The Web Audio API processes sound differently on each device, creating a unique signature.
• Screen & window metrics — Resolution, color depth, and pixel ratio narrow down your device model.
• Hardware details — CPU core count, device memory, and battery status reveal hardware specs.
• Network info — Your IP address reveals location, ISP, and organization.

How to Protect Your Privacy

• Use Brave Browser — it randomizes fingerprint data by default.
• Use the Tor Browser — standardizes all fingerprint data across users.
• Install a Canvas Blocker extension (e.g., CanvasBlocker for Firefox).
• Use a VPN to mask your IP address and location.
• Enable Firefox's resistFingerprinting flag in about:config.
• Avoid installing unusual fonts or browser extensions that make you stand out.
