Popular Science: Why and how to erase your browsing history. “Web browsers keep track of your past activity for a reason. That history comes in handy if you want to find a funny article again, or return to your favorite photo of the kids, or if restore a tab that you accidentally closed. At the same time, some people find this constant tracking a little on the creepy side. Not to mention that, if you share a computer with others, you might not want them finding out about a gift you secretly bought them, your interest in 1970s folk rock, or your more private Google searches.” I love disco and I am unashamed.
