I have been browsing the web with third-party #cookies disabled for a longer time than #Google have been contemplating disabling them in #Chrome, and I have yet to find a single website that doesn’t work without those. It feels like this is really only the problem for ad networks and nobody else :blobcatshrug:
One single good use case for them is third-party widgets where you do things that require authentication. Like those Disqus comment widgets you used to see everywhere.
