How do I allow Safari to generate logged-in thumbnails of HTTPS pages? Maybe there's a hidden setting for this?
Right now thumbnails of secure (HTTPS) pages are rendered without login data. For example, for private GitHub repo I see big "404" error. Most of my Top Sites thumbnails are login forms and error pages for various sites which makes "Top Sites" feature almost useless.
I'm aware that enabling logged-in thumbnails for Top Sites may have security/privacy implications.
