About

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

This add-on 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 add-on 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 add-on, 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.

This extension is made in collaboration with the author of "Canvas Fingerprint Defender":

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

Note 2: To report bugs, please visit addon's homepage (https://mybrowseraddon.com/font-defender.html) and fill the bug report form.
