Microsoft is continuing its move away from Adobe Flash with an update to Edge that’ll get rid of Flash content by default. The browser’s next release will “encourage the transition to HTML5 alternatives” by giving users more control over Flash. They’ll have to enable Flash content when a site is using it.
If you generally like to have Flash work, Edge can remember that preference and apply it in the future. In other cases, the content won’t appear unless you want it to.
