stop pop-under ads on safari

Hello John Comeaux,

On macOS

1. Open Safari
2. Open Safari's Settings (Command + ,)
3. Click Websites
4. Scroll down and click on Pop-up Windows

You'll want to make sure When visiting other websites is set to Block or Block and Notify. In the list of websites above, these are allowed to bypass the default option set by When visiting other websites. Make sure you block or allow these as well. I personally recommend setting everything to Block and Notify.

I hope this helps!

It is not an ad blocker, there is a difference. It should block up any prompts/windows that come from visiting or doing certain actions (such as clicking) on websites.
