I normally have 4 windows open, each with multiple tabs, for 4 work streams. Whenever Firefox or MS decides to do an update, one window sometimes, 4 rarely, none usually, are recovered after restart. How can I ensure that Firefox remembers all the windows and their tabs before shutting down? Then reinstates them after starting up. After the last MS update, the option "Recently closed windows" was greyed out. But there had been 4 of them. Firefox's recovery after simply rebooting the computer is more, but not completely, reliable. Win11 on a desktop computer Thank you
