Summary

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

This addon does NOT block the fingerprint, 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. webbrowsertools.com/font-fingerprint/). 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 Font fingerprint.

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

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