Additionally to then there's also the various things that track identity and behaviour. Tell me what you search and click, and I'll tell you what you think? (That's not fixed with a simple add-on of course.)

Regarding "I do not put sensitive and important data on my computer" and "I always work on remote hosts", I must respectfully disagree. Never mind the fact that you set a bad example for newbies, being so caviler with your own safety harms the security of the rest of us. Downloading and executing random software off the Internet---the raison d'être of modern web browsers---is a good way to get owned. Just because you don't use your computer for anything important doesn't mean that it cannot be compromised and used to attack me. Plus, if you use your computer to log into other computers to do real work, then your computer is extremely important! A successful compromise would give attackers all the same remote access you have. Admittedly, that's not what your everyday, ordinary malware is after, but it's the principal of the thing that bothers me.
