## Description

Auto Cookie Optout is a Chrome extension designed to help users assert their cookie preferences by automatically opting out of optional cookies on supported websites. Unlike traditional content blockers that may partially remove cookie popups, affect scroll bars, or cause website features to malfunction, Auto Cookie Optout actively communicates your choice to not consent to optional cookies, ensuring smoother website behavior.

Although this extension is no longer maintained, with a recommendation to switch to Consent-O-Matic, Auto Cookie Optout provides a privacy-friendly browsing experience by reducing intrusive consent dialogs and maintaining website functionality. Its open-source code is available for auditing, promoting transparency and trust.

For those who value minimal tracking and a seamless browsing experience, Auto Cookie Optout serves as a practical tool to enforce cookie preferences automatically and effectively.
