I recently stumbled across a couple of articles about firefox blocking 3rd party cookies by default:
http://arstechnica.com/business/2013/02/firefox-22-will-block-third-party-cookies/
.. so I decided to clear all my cookies and start blocking 3rd party cookies (easy to do in chrome)
But the huge laugh, is that ars itself had a HUGE number of 3rd party cookies blocked!
How do I know? Chrome shows a cookie icon in the omnibar when cookies are blocked. Click through shows the blocked sites. Look at that! 11 sites not at ars! I started to enter a /. article and .. guess what? Them too.
I usually don't worry about this sort of thing, but its easy for blackhats to install an "advertisement" on a site in such a way to also be a third party. Sorta uncomfortable for me, anyway.
.. yup .. three 3rd party cookies!
