How to see it in your browser
Open your site, press F12, then choose the “Application” tab (Chrome, Edge) or “Storage” (Firefox). This cookie is written by another domain: look for it under “Cookies”, under the service’s domain. If you cannot see it, your browser may be blocking third-party cookies.

Targeted advertising, remarketing and profiling require prior, free and informed consent. These cookies cannot be exempted.
How to prevent it before the choice
Same method as bcookie.
How OpenCookies handles it
Common services like this one are in OpenCookies’ tracker list: the banner neutralizes their script before the visitor chooses and only restarts it after “Accept”. The test shows whether this cookie appears before the choice, after “Refuse” and after “Accept”.
