When starting to type in the address bar the shown list often holds too many unrelated items. With a few shortcuts it can be a much better experience.
They’re to be typed directly in the address bar (press F6) in front of the search terms:
These I find the most useful:
- % search only open tabs
- ^ search only history
- * search only bookmarks
These are probably useful for other people:
- + search only tagged bookmarks
- # search only in titles and tags
- $ search only in URL
- ? show only (search engine) suggestions
It’s also possible to remove unwanted items in the list by selecting them and then press SHIFT+DELETE although it sometimes doesn’t work for me on FF82.
