Browser Fingerprint Test

What is browser fingerprinting?

Browser fingerprinting is a tracking technique that identifies you based on the unique combination of settings and capabilities your browser advertises. Individually, details such as your screen resolution, time zone, installed fonts, language preferences and graphics hardware are unremarkable. Taken together, they form a pattern that is often unique enough to single out one device among millions. Trackers compute a hash from these signals — much like the fingerprint ID shown above — and recognise you again on a later visit, even on a completely different website.

Why fingerprinting defeats cookies and incognito mode

Most people assume that clearing cookies or opening a private window makes them anonymous. Fingerprinting sidesteps both. Because it relies on characteristics of your hardware and software rather than a stored identifier, there is nothing to delete. Incognito mode hides your history from other people who use your computer, but the websites you visit still read the same screen size, GPU, fonts and time zone — so the fingerprint barely changes. This is what makes fingerprinting so attractive to advertisers and so difficult for ordinary privacy settings to stop.

How to reduce your browser fingerprint

You can shrink your fingerprint by blending in with the crowd. Use a mainstream browser with default settings rather than a heavily customised one, since unusual configurations stand out. Browsers like the Tor Browser and Brave actively resist fingerprinting by standardising values and adding noise to canvas and WebGL readings. Firefox offers a "resistFingerprinting" option, and disabling unnecessary extensions reduces the signals you expose. Keeping your browser updated also helps, because new versions ship privacy protections that randomise or hide the most identifying values.

For an extra layer, route your browsing through ProxyMule. While a proxy cannot rewrite every client-side signal, hiding your IP removes one of the most stable anchors trackers rely on to tie a fingerprint to a real-world identity — and it works instantly in your browser with no install.

Is the fingerprint ID above globally unique?

No. The ID is illustrative: it is a hash of the signals collected on this page, shown to demonstrate how easily your attributes combine into a stable identifier. It is not a real-world uniqueness percentile across all internet users, which would require comparing your values against a large reference dataset.

Why does my fingerprint change between browsers?

Different browsers report different user agents, render canvas and WebGL content slightly differently and may expose different APIs. That is why the same device can produce distinct fingerprints in Chrome, Firefox and Safari — and why switching browsers can be a simple way to break a persistent fingerprint.
