I didn't do anything weird, just closed firefox yesterday (8-3-13) and started it today (9-3-13) and it was gone. I have no idea how did could have happen, it still got all the cookies and my whole history is still there, so where did my save files go? I didn't do any update or anything just regular start. The only reason I want them back is because I played it for 12 hours so don't really want to start all over. No problems before with firefox so I'm really confused now.
