AudioContext Fingerprint Defender

Defending against AudioContext fingerprinting by reporting a fake value.

What is AudioContext Fingerprint Defender?

"AudioContext Fingerprint Defender" is a Firefox add-on that protects user privacy by altering your AudioContext fingerprint. Instead of blocking AudioContext or any web audio API methods, it introduces a minor alteration or 'noise' to the actual fingerprint and changes it on every site visit or page reload, making your actual fingerprint harder to track. It operates automatically with no settings or options to adjust, providing a simple and effective solution against tracking.

Summary

Analyze keywords

AudioContext Fingerprint Defender is a lite addon that let you easily hide your real AudioContext fingerprint by reporting a random fake value and protect your privacy.

This addon does NOT block AudioContext or any other web audio API methods, instead, it simply adds a small noise to the actual fingerprint and "renews" it every time you visit a website or reload a page. It is important to note that, this addon does not have any settings or options to adjust. Simply add it to your browser and start surfacing the internet. If you want to test this addon, please visit a website that show your fingerprint (i.e. audiofingerprint.openwpm). Every time you reload the page, you will see a new fake fingerprint.

Note 1: depending on your browser and platform, you may need to (Shift+Refresh) a web page to renew AudioContext fingerprint.

Note 2: If you also want to protect your browser against other types of fingerprints, please see my other addons: Canvas Fingerprint Defender, WebGL Fingerprint Defender.

Note 3: In order to report bugs, please visit addon's homepage and fill the bug report form.
