Check my name. I KNOW companies know more about this person than he thinks. How do I know this? Because, once, a long time ago, I wrote browser fingerprinting software for a security company that then spun it to be used for nefarious purposes (I say nefarious, but really, it is nothing more than what Google and FB do today). That was when I left.

The point being, it is really, REALLY, hard for someone to be invisible while browsing the modern internet. There are very few things you can do, but there are some things.

1. Install adblock 2. browse incognito 3. browse through a proxy (creates noise) and, the most important 4. use a plugin that randomizes queries to its components.

For #4, I don't know of any out there that do this effectively so I wrote my own.

The big take away from the article is that "nothing is stored locally"...well, most companies haven't been tracking that way for a long, long time.
