Features & Capabilities

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Although this extension is no longer maintained, with a recommendation to switch to Consent-O-Matic, Auto Cookie Optout provides a privacy-friendly browsing experience by reducing intrusive consent dialogs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.

Is Auto Cookie Optout Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Auto Cookie Optout requires a lot of sensitive permissions. Exercise caution before installing.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Auto Cookie Optout has earned a fairly good reputation and likely can be trusted.
