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.
