If you follow Web Privacy issues, you’ve probably heard about “Flash Cookies.” In the same manner that Web developers can use HTTP Cookies to store data, developers who use Adobe Flash Player on their Web site can use Flash Cookies to store data.
Internet Explorer users are accustomed to deleting their cookies via Delete Browsing History. However, because Flash is an add-on and not part of standard HTML content, browsers have not been able to delete Flash cookies the same way they delete HTTP cookies.
Adobe recently announced that Flash Player 10.3 integrates with Delete Browsing History. This means that when you delete your cookies with Delete Browsing History, Flash Player will automatically clear your Flash cookies as well. We applaud the change. It resolves a longstanding privacy issue.
