Features & Capabilities

Consent-O-Matic is a Chrome extension designed to automatically handle GDPR consent forms and cookie pop-ups that often aim to confuse users into agreeing to tracking. With this add-on, you set your privacy preferences once, and it automatically responds to consent requests on your behalf, preventing manipulation and preserving your privacy.

Developed by privacy researchers at Aarhus University in Denmark, Consent-O-Matic combines data from over 680 consent pop-ups into five manageable categories that you can toggle on or off according to your preferences. If categories do not exactly match, the extension opts for the more privacy-preserving choice to ensure your data remains protected. This tool helps enforce privacy rights under the EU's General Data Protection Regulation (GDPR) by simplifying user consent management.

User Reviews

Consent-O-Matic is generally helpful, saving time by automatically handling cookie prompts and offering a smooth, easy-to-use experience across devices. Many users report it works well on a majority of sites and reduces button-click fatigue. However, reviews also note notable drawbacks: performance is inconsistent across sites, with some pages doing nothing or just informing; the extension has limited site coverage and would benefit from community filter lists; and its effectiveness can vary by location, with reduced usefulness in Poland. Overall, strong timesaver with caveats.
Pros
  • Saves time and reduces cookie prompts across websites.
  • Very smooth and easy to use.
  • Works across multiple devices (mobile, tablet, PC).
  • Automatically rejects cookies without having to manually click through toggles.
Cons
  • Inconsistent performance across sites; often doesn't work on many pages or only informs the user.
  • Limited site coverage; needs community filter lists and broader site support.
  • Geographic limitations; reduced effectiveness in certain regions, notably Poland.

Is Consent-O-Matic 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.

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

  • High ******* ******* **** *** ****** ***** *** ***** ** ******* **** ********* ********* ** * *********** *****
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.

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