Automatically enforces user consent preferences for browser cookies.
Cookie banners often provide the user with a selection of different usage categories to consent to. But how can we be sure that websites really respect these choices? And what should one do about websites that do not offer consent choices?

Using artificial intelligence, the extension automatically assigns usage categories to observed cookies, and deletes those that belong to categories the user did not consent to. This way, you can enforce your cookie consent preferences, regardless of whether the website respects your choices.
Keep in mind that CookieBlock is experimental and still in development. The classifier isn't perfectly accurate, and some websites may break because of this. If you want to report a broken website or give general feedback, you can do so using the form at:
This add-on has been built by members of the Information Security Group of the Computer Science Department at ETH Zürich, and was developed as part of the master thesis "Analyzing Cookies Compliance with the GDPR".
