I totally forgot about Ad Nauseam! I used to use it instead of uBlock Origin (which, if I remember correctly, is what Ad Nauseam actually uses for its adblocking). Google banning it from their extensions marketplace only strengthened my loathing for Google and my resolve to use it. I don’t remember why I eventually stopped - probably the inconvenience. Now that I’m a Firefox user, I should pick that back up and give it a spin again. It was entertaining to see the visualization of all the ads it had clicked on.

I also used to use Chaff (https://chrome.google.com/webstore/detail/chaff/jgjhamliocfh...), which opens up a tab and browses on its own when the browser is idle and disappears when you start using it again. As with Ad Nauseam, the means of protecting privacy behind it is not anonymity, but rather obfuscation - muddifying your actual browsing behavior by flooding the data you leave behind with junk data (at which point it ceases to be data, I suppose). The problem with that extension was that I would sit back and wait for it to start browsing, and then I’d waste too much time watching it / customizing its behavior.

The book _Obfuscation: A User's Guide for Privacy and Protest_, written by the authors who developed Ad Nauseam and TrackMeNot, has a great chapter on chaff (the obfuscation tactic, not the Chaff extension mentioned above).
