Google has been planning to make HTML 5 default on Chrome for sometime. Today, the company has announced that starting September, Chrome will block behind the scenes Flash content.
Come September, Google Chrome 53 will begin blocking Flash, such as the kind that loads “behind the scenes,” as Google says, which can slow down casual web browsing. HTML5 is a lot less resource-heavy and when pages utilize it, it improves battery life, page loading and responsiveness across the web.
In December, Chrome 55 will make HTML5 the default experience, except for sites which only support Flash. For those, you’ll be prompted to enable Flash when you first visit the site. Aside from that, the only change you’ll notice is a safer and more power-efficient browsing experience.
Flash helped make the Web a rich, dynamic experience, and shaped the modern set of web standards. We continue to work closely with Adobe to ensure that your web experience is as fast and secure as possible and to help the Web transition to HTML5.
