This occurs by clicking a link on a web page or clicking on a history entry or a bookmark. It does not happen repeatedly with certain websites so I can't pin down a specific cause. Usually a reload will load the correct website. Reproducible: Couldn't Reproduce

If you have the ask toolbar please remove or disable it (see http://kb.mozillazine.org/Problematic_extensions#Ask.com_Toolbar ). If you do not please list what extensions you do have (see tools add-ons -> extensions, or use https://addons.mozilla.org/en-US/firefox/addon/3746 ).

Ask toolbar removed. I did not see it in the list of toolbars but I did see it in the Add-on extensions. I guess I installed it at some point. Time will tell if this is still a problem. Thanks.
