I just bought a brand new machine, xp media center, with latest FFox. I am truly not on drugs here, but it has happened to me several times a week: I clear "everything" every day before shutting down; about two days later, "old" history comes back into my History Tab. I have tried no tabs, no difference, suddenly some of old history comes back as if I visited today, a few "pages" ago, in the middle of what I actually surfed. I had a friend from work come over and it happened to him too. == This happened == A few times a week == bought a brand new machine
