User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:33.0) Gecko/20100101 Firefox/33.0 Build ID: 2014101000 Steps to reproduce: Open a new tab, type something in the url bar (like "moz"), then when the dropdown menu comes up, mouse over an entry (such as bugzilla.mozilla.org entry) so that it is highlighted. Then click the url bar that still has only moz in it. The dropdown menu disappears. Then hit enter. Instead of navigating to "moz" it will navigate to whatever the highlighted entry on the dropdown menu was (in this case bugzilla site), even though by clicking the url bar that menu disappeared. Expected results: Since clicking on the url bar makes the highlighted url go away, firefox should navigate for what is in the url bar.
