Hello, by default the firefox session restore feature only allows you to save last 3 windows open. to change this, type on: config in the address bar of firefox (confirmed the message information where it appears) and search for the preference named browser.sessionstore.max_windows_undo. Double-click it and change its value to 4 (or more).
