If you’ve been online at all in the last decade, you’ve heard of the “dangers” of HTTP Cookies. More nefarious and harder to remove are Flash Cookies as they are handled by a plugin/extension/addon to the browser and exist outside of the normal security settings.
To see or delete Flash data, you’ve got to visit the following URL:
http://www.macromedia.com/support/documentation/en/flashplayer/help/settings_manager07.html
You will probably be suprised to see many of the sites listed, as Flash is often being used to present you with ads in addition to the interactive elements that you might expect.
