When you first click in the address bar, before you type any text for Firefox to match off of, it shows the first 6-10 shortcuts from the built-in Firefox Home / new tab page. Depending on your preference, you have these options: (1) Curate the shortcuts to be sites you visit frequently so the list is useful. You would do this on the about:home page. See: [[Customize items on your Firefox New Tab page]] (2) Stop Firefox displaying shortcuts in the address bar when you click in it. You would do that on the Settings page. See: [[Address bar autocomplete suggestions in Firefox]] Can you get it working in a way that suits your needs?
