Firefox has a nice little feature that I really wish Edge had: if one of the address bar results are one of your bookmarks, there's a little star badge on the favicon. It's nice and useful to know which results are bookmarked. Also, doing this would solve a small new problem I've noticed: since Chrome and Edge have added the "Remove suggestion" button to address bar results, obviously that button doesn't appear when you hover over a suggestion that is one of your bookmarks, but to users they might not understand why that button doesn't appear next to some results (because there's nothing to indicate that it's one of their bookmarks). The bookmark badge would clear things up here.
