Frequently Asked Questions

  • 1. What is WebGL Fingerprint Defender?

    WebGL Fingerprint Defender is a multi-browser add-on that let you easily hide your real WebGL fingerprint by reporting a random fake value. According to many tech blogs, completely blocking WebGL API 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, this addon does not have any settings or options to adjust. Simply add it to your browser and start surfacing the internet.

  • 2. What is WebGL Fingerprinting?

    WebGL fingerprinting is a digital fingerprinting technique for tracking users and also allows websites to easily identify visitors using Web Graphics Library. In order to get more info about device fingerprinting please read this page in Wikipedia. In general, there are many fingerprinting techniques using various web browser APIs. This addon only protects you against WebGL fingerprinting. For protecting against other fingerprints (i.e. canvas, audio-context, etc.) please use other plugins.

  • 3. How can I work with this addon?

    As mentioned above, simply add this addon to your browser and start surfing the net. Your fingerprint will always be a random value and every time a page is reloaded, a fake value will be generated. In order to test this addon, please visit a website that shows your fingerprint (i.e. browserleaks). Once you see your fingerprint, please reload the page and you will see a new random value. While this addon is active, you are protected against WebGL fingerprinting. With WebGL API, two types of fingerprints can be generated. One with WebGL constants and the other with an image that is rendered with WebGL API. This addon can spoof both values at the same time.

  • 4. How does WebGL Fingerprint Defender work?

    This addon has a very simple logic. If a website wants to generate a fingerprint with WebGL API for your browser/machine, this addon interferes and adds a small random noise to the actual fingerprint (both type of fingerprints discussed above). This way, no one can identify your real fingerprint while you are browsing the internet and in every visit, a random fake value is reported. Please note that this addon can only protect you against WebGL fingerprinting and NOT other kinds of digital fingerprinting techniques.
