Years ago I had a discussion with a guy from "AdTech" company: Their companies was pushing out ads on several large websites - he said the first thing on a new computer is an Adblocker to get rid off all the shit his company is distributing across the net :-D

The first thing I do when I get access to any PC is install Firefox, then ublock ;)

The internet has been unbearable without it for years now. I can't imagine having to face it every day as most people do.
