Re: It's the Internet, all your privacy are belong to them!
"Well, I usually use Firefox, NoScript, and Cookie AutoDelete. Of course my main OS is Linux."
Currently I use Firefox configured for privacy/security, plus NoScript, Ghostery, Privacy Badger, and uBlock Origin, with no permanent trust, and a paid VPN service hosted in another country.
If I were seriously concerned about not being tracked in a specific instance, I would be using a VM running a read-only Linux image, hosted on my customary Linux OS.
