As CD's, closeted or just want to keep it private for whatever reason, we are always at the risk of being outed. Browser history, pictures in a folder, (I recently bought a secure pen drive and now store them there), box of clothes hidden where ever, walking by a window dressed, neighbor peeking in the windows, etc etc etc. With this lifestyle, there are 1000's of different ways of being outed. All of this is just if you don't leave the house, imagine if you do.
The thing about this post that bothers me most is trying to wrap my head around someone, anyone, using my PC. Beyond the history or pictures, you may have other things like banking and such you may not want anyone to see. So why even let someone use your PC?
On the other side, I do use firefox myself and it doesn't keep a history, or any other traces of where I have been or what i was looking at. Maybe tweaking your PC might be a good idea at this point just to be on the safe side
