Microsoft says that its next release of Windows 10 will default to HTML5 content when possible and won’t even load Flash content in the background, which should lead to better performance, battery life and security. If a site does rely on Flash, you’ll have to actively select whether you want Flash to load via a prompt.

Previously, Edge would pause certain Flash ads and content that weren’t central to sites, but stopping it from loading could move sites to speed up their transition to leaner, sager technologies. The click-to-run strategy has been employed by others, including Chrome.
The big caveat is that the change won’t affect some of the biggest sites out there, at least to start. Microsoft says:
We are deeply aware that Flash is an integral part of many web experiences today. To ease the transition to HTML5, these changes initially will not affect the most popular sites which rely on Flash today. In the coming months, we will actively monitor Flash consumption in Microsoft Edge and will gradually shorten the list of automatic exceptions. At the end of this process, users will remain in control, and will be able to choose Flash for any site they visit.
Microsoft isn’t clear on exactly how long this transition process will be, but it’s nice to know one more browser is putting its foot down against the scourge of the internet. Windows Insiders will get an early preview of the new Flash-blocking features in an upcoming update.
