That's me. I have most of my browser settings turned up to "paranoid" (no history, no sync, no 3rd party cookies, all cookies purged upon exit, separate profiles for web and gmail, etc.). I use uBlock Origin, and have a 15,000 line /etc/hosts file. I only see ads if they are served inline directly from the site I'm visiting (thankfully that's very few).
