Safari will start blocking all Flash content in macOS Sierra
Google Chrome’s development team announced in May that the browser will stop showing Flash content without prior user approval, except for a few top sites such as YouTube and Facebook.
Now, with the advent of macOS Sierra, Apple’s Safari browser is joining the party. But it’s taking it a step further: It will replace Flash content with HTML5 if possible, and if not, it will simply block all Flash content until the user explicitly approves it.
