Javascript can use CSS attributes to see if you've visited a specific URL, which is unfortunate, but that's a long way from saying that your history is an open book. Javascript cannot directly access your history. A script cannot enumerate all of the sites you've visited, it can only test specific, complete URLs. As far as cookies go, you're even further from the truth. A script can only access cookies whose domain matches the origin of the script.
