Is it possible to eliminate recently closed tabs and windows to insure complete privacy

There is a setting to eliminate history being saved, but by clicking on recently closed windows, for example, at least some history becomes immediately available, and is not eliminated by setting the history feature to never retain history. Is there a way to eliminate any possibility that someone could discover your search activities beyond the history setting?

It is best to avoid opening windows and only open links in a tab.
Firefox will always remember at least one window.


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.
