how do I clear the recently closed tab history
When I clear the history I find that it has no affect on the recently closed tab history. How do I clear it and protect my privacy. The tab history defeats the purpose of clearing the history because every site you were on is still listed.

You can (temporarily) set the pref browser.sessionstore.max_tabs_undo to 0 to clear the "Recently Closed Tabs" list.
If you want to re-use the "Recently Closed Tabs" feature (Undo Closed Tabs) then you can reset the pref browser.sessionstore.max_tabs_undo to the default value via the right-click context menu.
