Microsoft today announced a neat little feature that will improve the overall browsing experience using Edge browser. With the upcoming Anniversary Update to Windows 10, Microsoft Edge will intelligently auto-pause content that is not central to the web page. For example, content like Flash animations or Flash ads will be displayed in a paused state unless the user explicitly clicks to play that content.
This new change will significantly reduces power consumption and improves performance of the page. As you expect, video and games running using Flash, will not be paused. In the future, Microsoft will provide users additional control over the use of Flash.
Flash has been an integral part of the web for decades, enabling rich content and animations in browsers since before HTML5 was introduced. In modern browsers, web standards pioneered by Microsoft, Adobe, Google, Apple, Mozilla, and many others are now enabling sites to exceed those experiences without Flash and with improved performance and security. This transition to modern web standards has benefited users and developers alike. Users experience improved battery life when sites use efficient web standards, lowering both memory and CPU demands. Developers benefit as they are able to create sites that work across all browsers and devices, including mobile devices where Flash may not be available.
