Dear community,

I understand that tracking of third-party cookies is now FireFox' default. However, I put my FireFox privacy options to "strict" and opened the website tui.com. What I see in the web developer tools is that several cookies are set, which are not tui.com itself (please see screenshot). The first might be exlainable since it is a subdomain (?), but why are the second and third set? However, when clicking on the data protection icon in form of a shield next to the "ssl-lock" I see a lot of ther third party cookies are prevent. Why arent the second and third in the screenshot?

Thank you very much for your time!

Felix

Sorry for the late answer.

I don't really follow your answer: of course this comes from the site.the question to me is: why would Firefox not block the access to the last two domains since I have third party cookies blocked?

Firefox uses cross site cookie isolation and only this website can access those cookies. Some such cookies are essential to let the website work properly and blocking them can cause issues.
