On version 30, I am finding that I cannot save websites directly to Instapaper (i.e. clicking on the Instapaper button directly, which sits on my Favorites toolbar). Instead, a new website greets me with the following message: "Under normal circumstances, you shouldn't need to see this page. Please check your browser’s cookie settings and enable unrestricted third-party cookie access for www.instapaper.com. If you’re being sent through this page, Instapaper’s support for logged-in sites cannot function properly." In Options, I have the "Accept cookies from sites" box checked, and I have the "Accept third-party cookies" setting on to "Always." Is there something else I need to adjust in order to properly use Instapaper? Thanks!

You can see if there is a special permission saved for this site in the about:permissions page as well. In that page search for the instrapper site and see if there is a difference.
