To post comments and have your Disqus login information remembered across pages, cookies - specifically, first party (and in some browsers, third-party) cookies - must be enabled.
Third party cookies
Disqus doesn't require third party cookies to be enabled for basic functionality (like posting), but they are required to keep you logged in between pages in some browsers. If you're using Safari or a new version of Firefox, you won't need to enable third-party cookies to stay logged in because those browsers consider our cookies to be "first-party" because they're used in a trusted way.
If you're using a browser other than Safari or Firefox and you'd rather disable third-party cookies for all sites, but you'd still like Disqus to remember that you're logged in, simply add an exception for disqus.com and its subdomains to your cookie settings. Instructions on how to do that are noted underneath each browser below.
Single Sign-on
Disqus doesn't store an authentication cookie when signing in with Single Sign-on (website-specific profiles). The site is required to pass the user authentication each time the user loads the comments.
