With the focus on mobile and other exciting new features, you may have missed that Flash Player 10.1 supports the private browsing modes in many of the latest browsers.
End-users are becoming increasingly savvy about their online privacy, and private browsing lets you browse the web without storing any history on your computer. With Flash Player 10.1, the plugin will now automatically clear stored data in accordance with your browser’s private browsing settings.
See the new Private Browsing in Flash Player 10.1 article for more information about how private browsing mode impacts Flash Player behavior for local storage and settings. If you’re a developer, there is a section that describes how this feature may impact your use of local storage and content when a user is in private browsing mode.
