I mentioned Adsense for Search (AFS) and toolbars, but it seems Google now limits AFS to websites with search boxes. In pre-Chrome era, it let many toolbars for IE (7 or even 8, they both sucked) monetize this way. This toolbar support went away around 2012 as the Chrome Hegemon took over. AFS never allowed a browser (vs. a toolbar) to monetize from omnibox-style UX, no surprise. Monopoly behavior was on display even before Chrome took 2/3rds of the browser market.
