I went to forget around on Armor Games a while ago (very nice website) and when I went to close Firefox, it took a few minutes. I left the computer for a while and when I came back, it said there was an "IP address problem". So Firefox was completely frozen, so I decided to log off. When I logged back on, my computer acted like this was the very first time I was using it. All my files were deleted, my entire browsing history, and any other indication that I had used my computer before. This isn't necessarily a bad thing, but it is pretty damn confusing. Any advice?
