ClientRects Fingerprint Defender

Defending against ClientRects fingerprinting by reporting a fake value.

What is ClientRects Fingerprint Defender?

"ClientRects Fingerprint Defender" is a Chrome extension designed to protect users from ClientRects fingerprinting by reporting random fake values. The extension modifies the output of the native getClientRects() method, which is used to identify users based on element metrics. By adding a layer of noise and refreshing the fingerprint each time a page is visited, it enhances user privacy. To disable the add-on, users can easily do so from their browser's extensions page, with no options page available. For feature requests or bug reports, users are encouraged to visit the add-on's homepage.

ClientRects Fingerprint Defender is a browser extension that lets you easily hide your real ClientRects fingerprint by reporting a random fake value.

The native getClientRects() method in JavaScript returns a collection of rectangles (DOMRect objects) that enclose an element border-box in the viewport. Using the metrics from this method (i.e. x, y, width, height, etc.) one can generate a fingerprint to identify users. This add-on adds a small noise to the actual fingerprint and renews it every time you visit a website or reload a page. To disable this add-on, please visit the extensions page in your browser and then click on the disable button. Please note that this add-on does not have any options page.

If you have a feature request or found a bug to report, please fill out the bug report form on the add-on's homepage (https://mybrowseraddon.com/clientrects-defender.html).
