Auto Cookie Optout is a Firefox extension designed to enhance user privacy by managing cookie consent on websites. It allows users to opt out of optional cookies on supported sites, ensuring a smoother browsing experience without the annoyance of cookie popups. Unlike traditional content blockers that may disrupt website functionality, this tool communicates directly with websites to convey the user's cookie preferences, promoting a more consistent user experience.

The extension effectively resolves common issues associated with cookie consent popups, such as incomplete removal of notifications and dysfunctional site features. By actively informing sites of the user's consent decisions, Auto Cookie Optout ensures that browsing remains uninterrupted and user-friendly. Additionally, users can review the source code for transparency, available on GitHub, reinforcing the extension's commitment to privacy and security.
