I was actually surprised to find out that Firefox has ads on the new tab page. Discovered this when I accidentally forgot to turn off my VPN connection to an US server and Firefox took this as a sign to display ads. You can turn them off manually in the settings but since I never got them in Europe, I'd left the setting on its default value ("Please show me ads").
