    Are you saying that those cookies are created by DataTables?

    The library doesn't create any cookies (its open source, you are welcome to verify that). We use a PHP session cookie and Google Analytics on this site which is where the cookies on this site come from, but they wouldn't be added to your site, unless you are embedding one or more of our pages. Just including the JS library won't cause those cookies to appear on your site.

    If you need any further guidance with that, we'd need a link to your page.

    This one is the cookie used by CloudFlare as part of their network, which we use for our CDN. It does help improve performance from what they’ve told me.

    That is the only one that your users would get from accessing DataTables on our CDN. The other cookies are used for login and analytics if you visit our main site (e.g. the documentation or this forum).

    Would also appreciate a resolution path to this - Firefox also reporting
    Some cookies are misusing the recommended “SameSite“ attribute
    Cookie “__cfduid” has been rejected because it is in a cross-site context and its “SameSite” is “Lax” or “Strict”.

    Me too! There is very little I can actually do about it since the cookie is set by CloudFlare rather than myself. I'll see if I can get anything more from their support.
