Google will stop some Flash content from automatically playing starting Sept. 1, a move it decided on earlier this year to improve browser performance. Flash, made by Adobe Systems, is still widely used for multimedia content but security and performance issues have prompted calls to move away from it. Google already converts Flash-based advertising content to HTML5, which allows certain types of videos to be played natively in Web browsers without additional software plugins. Users will have the option to play the content, but they will need to adjust browsers settings to automatically play content requiring a Flash plugin.”]
