Chrome also now gives you more control over the data that websites store on your computer. This includes Flash Player’s Local Shared Objects (LSOs), which were previously only manageable using an online settings application on Adobe’s website. We’ve worked closely with Adobe to integrate Flash LSO deletion directly into Chrome, making it easier for you to manage your online privacy.
