Block Popunder Windows from Offensive Sites in Safari
Ever discover a popunder window hanging around on your Mac?
Every now and then I discover a MacKeeper (no link for them) popunder window after reading a local news site.
It's sleazy to be sure, and I'm sure they aren't the only ones (although I can't think of any other company that does it). If you find that happening on your Mac when using Safari, use this extenstion: https://extensions.apple.com/details/?id=com.mindfulbrowsing.safariextension-XWDSDPD7GS
The next time you see an offensive site in Safari, just click the "block this website" button.
