Dunno how this is still for free out here. Must-have extension for every browser.

Perfect in absolutely every way you can imagine. A must have.

Simple no other extension is as good as this ones at what it does.

In a Internet full of spam, pop-ups and annoying ads, this is a MUST HAVE for everyone (combined with Ghostery), on every device.
It just doesn't block ads, it makes every site much more readable (especially newspapers that are always full of junk).
It blocks malicious code, suspicious sites and almost eveything that shouldn't be in a webpage. It makes the everyday use of Internet much better.
