Hi, I just updated my firefox browser. And had numerous tabs that were still open. Usually when I have update it I go to history and click on recently closed windows/tabs and everything comes back on. But this time, there's nothing there! I'm missing all of the windows/tabs that were opened before. I look in my history tab and there's nothing there either from the time the firefox was updated. Before Firefox had something called restore previous session. And that's not there either. Can you please help me get my old tabs/windows opened again? Please
