This browser needs to have an extension that will save all open tabs and tab history to a file, so that all or selected previously open tabs in all previously open windows prior to restart can be reopened on command. This is to say not just on re-starting the browser, but also while the browser is open with perhaps only the initial tab open. A good example of this would be the Session Manager extension offered for Firefox. The current settings selection is not acceptable, since it does not work all the time. It is especially important when the menu item "History -> Reopen Last Closed Window" does not appear, which is happening to me at this writing.
