I don't mean to be a curmudgeon, but why put out this kind of privacy-minded plugin for Chrome, one of the browsers I'd probably least trust to respect my privacy?
Google has actually blocked similar "noise generation" apps from the Chrome Store in the past. As I recall, there were a few extensions out there that would 'click' on every ad displayed. Obviously that would have created serious problems for Google, so they nixed it.
It estimates since I installed it that I've cost advertisers $460 in clicks.
