I need to reset/change/clear my cookies, probably clear my cache, and change my history preferences. When I use the Tools-Options choice to bring up the appropriate menu (General, Tabs, Content, Applications, Privacy, Security,and Advanced) all allow me access to make changes (or not), the PRIVACY tab does not open up. It does no allow access to any info contained there in. It is like it doesn't exist or isn't even there. Also, in the Tools menu on the Firefox toolbar, both "Stop Private Browsing" and "Clear Recent History" are grayed out. What gives? Thank you for your help.
