I want to create some sort of software/plugin that when people download it makes their homepage (of chrome, firefox, whatever) the homepage of my search engine, which looks exactly like google (and uses their search results), but displays my ads from my adsense account. I've seen a few of these around but can't find any examples right now. Does anyone have any links to some more info about how to get this started? Just looking for some basic info right now about how it all works... Thanks!
