I don't like searching with Google while logged into Gmail because I don't want Google to have that data about me even if I have web history disabled. I've noticed that after signing out of Gmail they still leave quite a few cookies. Like the paranoid person I am I always delete cookies after using Gmail. Am I wasting my time? Would they use that cookie to track searching habits after having logged out?
Is there any greasemonkey script or addon that deletes the cookies for a particular domain everytime the tab is closed? How would I go about programming it myself?
