clear recently closed tabs
I have cleared my history., and cache., but how do I clear the "recently closed tabs" list. I want to clear all so no one can see what tabs I recently closed.

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
