- Type a domain you haven't visited before, i.e geise.de, and hit enter. - Close the tab and open a new one. - Type "geise.de", press down-arrow and hit delete to remove the "Visit"-entry - Open the history and search for geise.de ER: geise.de should be gone. AR: geise.de is still there. Before unifiedautocomplete, or with UA disabled, the selected entry was deleted from the history when hitting delete in the awesomebar-results-pane.

this happens for a UI glitch, the first entry is different than the others, it doesn't support history removal. fwiw removals are a not very discoverable option, so this is not going to block the feature. we plan a redesign that could address the issue by showing a visual removal option (or a context menu)

Maybe showing the normal result below the "Visit"-option would work too. Currently, only the "Visit"-option is shown.
