About AudioContext Fingerprint Defender

AudioContext Fingerprint Defender is an extension that let you easily hide your real audiocontext fingerprint by reporting a random fake value and protecting 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 shows your fingerprint (i.e. audiofingerprint.openwpm). Every time you reload the page, you will see a new fake fingerprint. Note: depending on your browser and platform, you may need to (Shift+Refresh) a web page to renew the AudioContext fingerprint. To report bugs, please visit the addon's homepage (https://mybrowseraddon.com/audiocontext-defender.html) and fill out the bug report form.
