Automatic handling of GDPR consent forms

Install Compare

Consent-O-Matic is a Chrome extension designed to automatically handle cookie consent pop-ups related to GDPR regulations, eliminating confusing and manipulative dialogs. Developed by privacy researchers at Aarhus University, it allows users to set their cookie preferences once and then automatically applies them on supported websites, enhancing online privacy without hassle.

The extension currently supports consent managers like Cookiebot, OneTrust, QuantCast, and TrustArc. It categorizes data processing into five user-selectable categories, always opting for the more privacy-preserving choices when exact matches don't exist. As an open source project, Consent-O-Matic invites community contributions to expand compatibility and improve functionality. Recent updates include fixes for manifest v3 compliance and bug resolution to ensure pop-ups are closed properly after consent is handled.

User reviews

Consent-O-Matic is praised for saving users time by automatically managing cookie consent pop-ups across many popular websites and CMPs. Its open-source nature and ability to remember preferences enhance the browsing experience. However, it often fails on niche or country-specific sites, causing issues like undismissed pop-ups or navigation problems. Some users report performance slowdowns. Regular updates and user feedback are needed to improve its coverage and reliability.

Pros

Saves time by automatically handling cookie consent pop-ups, reducing the need for manual clicks.
Convenient to set cookie preferences once and apply them across multiple websites.
Works well with many popular cookie consent managers (CMPs) and supported by an open-source transparent community.
Improves browsing experience for users who dislike constant cookie pop-ups and enhances browsing speed without ad blockers in some cases.
Generally reliable with many users recommending it after extended use.

Cons

Does not work effectively on all websites, especially niche sites or those using unsupported custom cookie consent forms.
Fails to detect or handle cookie pop-ups on several European sites and certain country-specific pages (e.g., Czech, Danish).
May cause website navigation issues on some sites, such as redirecting users unexpectedly after handling consent.
Occasionally causes browser slowdown or performance issues according to some users.
Requires user participation in submitting unsupported sites to improve compatibility, which may be inconvenient for some.

Simply had no effect at all.

Opfanger desværre kun få cookie pop ups, selv på danske hjemmesider registrere den stort set ingenting.

Extension safety

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.

Consent-O-Matic requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk likelihood

Risk likelihood measures the probability that a Chrome extension may turn malicious. This is determined by the publisher and the Chrome extension reputation on Chrome Web Store, the amount of time the Chrome extension has been around, and other signals about the Chrome extension. 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 Chrome extension.

Consent-O-Matic has earned a good reputation and can be trusted.
