When I do the Tools tab and then the 'clear recent history' link which clears out cookies and cache and all, it deletes everything and he gets suspicious over that, so that's why I'm doing the "forget about this site" option instead.
However, my husband is a computer repairman and despite deleting those sites from the history, he somehow found them... then proceeded to rant and rave about "dumb people not knowing that clearing your history does not get rid of everything like they think, and a computer repairman can still find out where you went." How is this even possible?? How can I clear my history ALL THE WAY and what is he talking about? What secret cache is there?
