Is CookieBlock safe?

Clean risk

CookieBlock loads a GitHub known-cookie list that can affect how it classifies and removes cookies.

CookieBlock’s default settings fetch a known-cookie list from GitHub and use it before the bundled list or local prediction when classifying browser cookies. Those labels feed the extension’s cookie policy, which keeps necessary and functionality cookies by default and removes analytics and advertising cookies.
