Google on Tuesday will begin pausing Flash ads by default in Chrome. The move is designed mainly to help improve browser speed and improve battery life. Flash ads are a major part of the Web right now, much to the frustration of many users and security experts. Google has been converting many new Flash ads on its platforms to HTML5 when they re uploaded through AdWords and other tools. The company is now encouraging advertisers to convert to Flash ads that aren t eligible for automatic conversion by Google itself.
