    MDN lists how different browsers prevent this: <a href="https:&#x2F;&#x2F;developer.mozilla.org&#x2F;en-US&#x2F;docs&#x2F;Web&#x2F;Privacy&#x2F;Guides&#x2F;Third-party_cookies#how_do_browsers_handle_third-party_cookies" rel="nofollow">https:&#x2F;&#x2F;developer.mozilla.org&#x2F;en-US&#x2F;docs&#x2F;Web&#x2F;Privacy&#x2F;Guides&#x2F;...

    Firefox, Brave and Safari do. Chrome and Edge do not.

      Not an accurate summary. That link actually says:

      &gt; Google Chrome doesn&#x27;t block third-party cookies by default, only in Incognito mode, or when users explicitly set it to block third-party cookies via chrome:&#x2F;&#x2F;settings.

      Looks like the settings let you block all third-party cookies and add exceptions for specific sites, which seems a bit awkward but could be made to work.

      Alternatively, you could run OpenAI in its own profile, or look into what extensions might do.

        I think that if they don’t block by default, is quite significant. Chrome + Edge has superior marketshare and then add the % people who have no idea what these mean and don’t change defaults.
