Internet Explorer now gives you more control over the data that Web sites store on your computer. This includes Flash Player’s Local Shared Objects (LSOs). We’ve worked closely with Adobe to integrate Flash LSO deletion directly into Internet Explorer, making it easier for you to manage your online privacy with the latest version of Adobe Flash and IE9 (as well as IE8):
IE will delete your Flash Cookies as well as your Web cookies
If you want to try this out, please visit our Test Drive Web site where you can create a Flash Cookie and then delete it. If you want to manage all the Flash settings, visit the online settings application on Adobe’s Web site.
