Slightly Off Topic: I could never understand how browsers made money, So if somehow i fork an browser and manage to market it to 10M users, all of a sudden i get money?
Edit: I know they are from Ads and searches, but i never quite grasps the economics behind it.
Search engines pay Firefox (and probably other browsers?) to direct traffic to them through the browser search box/awesomebar. I don't know the specifics, but I think a firefox-specific query parameter is included in the searches.
If you want to do this on your own I guess you'd have to make deals with the search companies? I don't think folks will automatically start paying you :)
