What Is a Browser Fingerprint?
A browser fingerprint is a collection of data points your browser reveals to websites: screen resolution, installed fonts, browser version, operating system, timezone, language settings, and more. Combined, these create a unique identifier that can track you without cookies.
How Fingerprinting Works
Websites use JavaScript to query your browser's properties. Each combination of settings is slightly different, making your fingerprint unique. Even clearing cookies doesn't reset your fingerprint — it stays the same across sessions.
What Makes You Unique
Screen resolution, installed fonts, browser plugins, WebGL renderer, canvas rendering, audio context, and timezone are the strongest fingerprinting signals. Most users have a fingerprint that's unique among millions of visitors.
How to Reduce Your Fingerprint
Use Firefox with Resist Fingerprinting enabled. Install the Canvas Blocker extension. Use a standard screen resolution. Keep your browser updated. Disable unnecessary plugins. Use the Browser Fingerprint Checker to test your changes.
Limitations of Fingerprint Protection
No method provides perfect protection. Some anti-fingerprinting techniques can break websites. The goal is to make your fingerprint less unique, not to become completely invisible. Combine with IP hiding for better overall privacy.
