Integration with browser privacy controls for managing local storage – Users will have a simpler way to clear local storage from the browser settings interface – similar to how users clear their browser cookies today.
Representatives from several key companies, including Adobe, Mozilla and Google have been working together to define a new browser API (NPAPI ClearSiteData) for clearing local data, which was approved for implementation on January 5th, 2011. Any browser that implements the API will be able to clear local storage for any plugin that also implements the API.
The ability to clear local storage from the browser extends the work we did in Flash Player 10.1, which launched with a new private browsing feature integrated with the private browsing mode in major browsers, including Google Chrome, Mozilla's Firefox, Microsoft's Internet Explorer, and Apple's Safari.
