http://blog.chromium.org/2011/04/providing-transparency-and-controls-for.htmlChrome has updated its dev release (kind of like a nightly-built beta release that you can download and use if you wish) to include support for managing your flash cookies.
For those you are unfamiliar with such a concept, your HTTP cookies are tracked, cleared, and managed within the privacy controls of most browsers - but Adobe Flash lets web developers store and manipulate local data within the plugin itself. It's a complete disaster. For instance, a nasty web page might show no cookies being used for tracking data - while storing a 0px by 0px flash plugin instead.
Most browsers will be adopting this within the next year - or if you are a Chrome user, check it out now =)
