“Flash cookies are a new way of tracing your movement and storing a lot more information about you than with normal cookies. … you can’t locate them in your browser. … not shown in the list of cookies that you can see when you take a look at the cookies … in your web browser.”
The easiest way to reach the Flash Cookies list of your flash player is through a special page on macromedia.com. At this point, most people who know how to delete browsing histories or http cookies probably haven’t even heard of flash cookies and are left with a false sense of privacy. Adobe is being irresponsible when they chose to not have the cookies list present in the settings dialog you get by right clicking on any flash applet.
