''How do I disable the Ask.com toolbar'' Hi David, There are instructions that can be found starting in Problematic extensions, that point to a special topic on uninstalling toolbars. * Problematic extensions - MozillaZine Knowledge Base<br>http://kb.mozillazine.org/Problematic_extensions * Uninstalling toolbars - MozillaZine Knowledge Base<br>http://kb.mozillazine.org/Uninstalling_toolbars '''Then to fix the default search engine''' used at the Location Bar, change the value of '''keyword.URL''' in '''about:config''' to one of the values shown in [http://kb.mozillazine.org/Location_Bar_search#Location_Bar_search_.28external_-_search_engine.29 Location Bar search] at MozillaZine with right-click then modify. If you are not familiar with about:config that is what you type into the location bar. If you've never used it it will produce a nasty message, but before dismissing it be sure the uncheck the checkbox first.
