DFPM – Chrome extension to detect JavaScript fingerprinting

In plain words

DFPM is a Chrome extension designed to detect JavaScript fingerprinting on websites. Launched in 2018, it helps users identify when sites attempt to collect device or browser information for tracking purposes. The tool is useful for anyone concerned about online privacy who wants visibility into fingerprinting techniques. The extension is open source and available on GitHub, making it accessible for both general users and developers interested in understanding fingerprinting methods.

  FingerprinterJS – A tiny JavaScript library for browser fingerprints2025 · github.com · ▲24

  I made FingerprinterJS, a small library with no dependencies that creates browser fingerprints from signals like canvas, WebGL, audio, fonts, userAgent, and screen info. It’s written in TypeScript, lets you enable/disable collectors, add custom data, and includes a simple suspicious-activity score. Would love feedback.
