I removed the finger-printing from my browser with degoogle: https://github.com/tycrek/degoogle - Alternatives to google/other big platforms. Firefox addons at the top. I scream this and my love for Linux from the rooftops, hoping other people show the love for the internet and things like I do and don't put up with the exploitation. It's _OUR_ psychyes and their psychological manipulation, and our future generations they're going after.

Our browsers could have been exploiting things behind NAT this entire time. Smart TVs, Smart watches, phones, anything pingable on your LAN. Go here and see it in action: http://samy.pl/webscan/
