I'm happy to see that Apple is still supporting Sierra and El Capitan even though machines that run Sierra all support High Sierra.

They seem to be aware that not everyone can upgrade due to software compatibility issues and are providing continued support for some time.

I wish they'd do the same for iOS, though.

What that does is if you have a content blocker (adblocker) installed, it will allow you to control what sites it runs on. Not just any adblocker will work with this. It needs to be one of the newer "content blocker" style. I'm using the Adguard ('https://safari-extensions.apple.com/details/?id=com.adguard.safari-N33TQXN8C7') content blocker extension.

Once you have that extension installed you will see the option in that screen to enable/disable by site. See my screenshot.

I just turned off Adblocker, and got Adguard, and am noticing that Safari is WAY faster now!

Looks as nice as before...
Anyone knows what Content Blocking does? It doesn't seem to suppress Ads (like on this page).
