title: Why are Chrome exceptions for third-party cookies not working (results in inability to use Disqus)?
body: <p>So Disqus has not been working for me for some time, and they finally, handily, added a little  notification that it's due to third party cookies being blocked. Great, I said, let's take care of that.</p>
  
  <p>So I added an exception for disqus.com to Chrome's preferences, but it does not seem to be working. I did this vis Preferences -> Advanced -> Content Settings -> Manage Exceptions, where I have added an 'allow' exception for <code>disqus.com</code>. I have third-party cookies otherwise blocked.</p>
  
  <p>Disqus still doesn't work, though, giving me the same error on every site that it's unable to work with third party cookies. The error persists even if I go to disqus.com and login, then revisit a site.</p>
  
  <p>Why might disqus be failing here?</p>
