So, I just started using Windows 7 like 3 days ago. I'm a very experienced computer user. Everything was good. I go and take a shower and come back and my Firefox window is closed. OK, that's fine, maybe one of the kids was messing around, I'll just open Firefox back up. The icon is not in the taskbar that I pinned it to. On second thought, it is in there but it's missing it's typical icon graphic and displaying the windows generic one. OK, this is weird, time to reboot.
Rebooted and it's the same windows generic graphic icon for firefox. What could have happened?
