Created attachment 462922 [details] Screenshot showing the working and not working icons on the start page This is only tested on macOS 12.6 with safari 16.0. When using self signed certificate it does not show the icons in the start page on either "favorites" or "reading list". We trusted our own certificate like this: Download the certificate to the mac and open the KeyChain and trusted the certificate added it in "system" chain and then trusted all. Then the favicons in the tabs and bookmarks in the booksmarks menu worked fine, and the site have padlock when on it and safari say it self it trusted. Everything else from "favorites" and "reading list" icons works fine what we could tell. Safari doesn't complain at all about this self signed certificate at this point. To identify this we set up a site with LetsEncrypt certificate and then "favorites" and "reading list" icons start working. Why does the "favourites" and "reading list" icons work differently here w.r.t the certificate?

Thank you for the report! Favorites and Reading list are Safari features, not WebKit ones. Could you please report this to Apple via https://feedbackassistant.apple.com ?
