Out of the blue, browsing on Firefox, it shutdown by itself, and 30 minutes later reloaded itself. Unfortunately, it loaded a very old tab session. I lost all my work, and had to start over. History was gone, couldn't reload recently opened tabs. I started all over, reloaded all my old tabs and addons to a new firefox page. 30 minutes later, my old tabs suddenly reappeared, out of nowhere. This time, I selected and saved all the tabs. Unfortunately, this won't help if I lose the entire Firefox web page. Is there a way to save the entire Firefox work space entirety, by exporting? If not, there should be. Does anyone know why this glitch happened, in the first place? thanks, Wa
