About

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).
