About Canvas Fingerprint Defender
Canvas Fingerprint Defender is a lite extension that lets you easily hide your real canvas fingerprint by reporting a random fake value.
According to many tech blogs, completely blocking canvas fingerprints is not a good idea, therefore reporting a "fake" fingerprint could be the best solution to better protect your privacy. This addon 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, it 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. browserleaks). Every time you reload the page, you will see a new fake fingerprint.
To report bugs, please visit the addon's homepage (https://mybrowseraddon.com/canvas-defender.html) and fill out the bug report form.
