Google Chrome’s development team announced this past May their browser will only display Flash content after its approved, except for a few top sites like YouTube and Facebook.

With macOS Sierra Apple’s Safari browser is taking this idea a step further by replacing Flash content with HTML5 when possible. Otherwise, it will simply black all Flash content until the user approves it.

This information was released by Ricky Mondello, an Apple developer.

“On websites that offer both Flash and HTML5 implementations of content, Safari users will now always experience the modern HTML5 implementation, delivering improved performance and battery life,” he wrote.

And unlike Chrome, Safari will have no “whitelist” of top sites where Flash is allowed.

“This policy and its benefits apply equally to all websites; Safari has no built-in list of exceptions,” Mondello wrote.

We’ve been using HTML5 for years, so it’s time to get on board to avoid users having to approve content and increase bounce rates.
