I didn't notice that pop ups 'cause I use Google Chrome with uBlock.

Even better... I always use Google Chrome Canary for porn, and a normal Chrome for everything else (both with uBlock). You can avoid porn links in your search bar in that way.

If you use Chrome, just click on the link and push install. :
