AudioContext Fingerprint Defender Extension

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.

Stanton McCandlish (ID: 000000d983c1d3d1) Voted 5 ★ - Updated 03/31/2021 Does exactly what it should do and claims it does. Tested at: * https://audiofingerprint.openwpm.com/ - defeated all 4 types of audio fingerprinting * https://webbrowsertools.com/audiocontext-fingerprint/ - defeated all 4 types of audio fingerprinting * https://browserleaks.com/features - defeated the general "features detection" fingerprint (site doesn't have an audiocontext-specific test) I like that this is a 1-exploit fix (well, TECHNICALLY a 4-exploit fix) instead of a plugin claiming to spoof all forms of user fingerprinting, since new methods of that come up all the time. It's better to be certain that you have a particular weakness patched up because you have an extension that corresponds to it exactly, than to go without preventing a leak because you assumed it was included in some catchall extension but it wasn't. PS: Anyone who cannot figure out that they can click on the extension's icon and pick "Show|Hide desktop notifications" simply doesn't DESERVE to use this extension. Heh. Really, the developer should just turn this option off by default, since it's obviously the only thing causing unhappy feedback.
