how do I click ok to do this? Double-click the browser.sessionstore.max_tabs_undo preference to display a dialog where you can enter the desired value, which in your case might be 0 and then click OK. I have an HP desktop running windows 11 and have been unable to prevent history from keeping recently closed tabs.
