under options > privacy > location bar i have "suggest" set to: History.

if i clear my history and click the down arrow for the location bar, entries from my bookmarks are still showing up. how can this be when i cleared my history and then never visited any of these sites? if firefox is set to only use history to populate entries into the location bar, then why is it placing entries into the location bar that are from my bookmarks? even though i never visited them since clearing the history?
