Install ScrollMaps and you can use two-finger scroll in various online maps. It's designed for Mac trackpads but because of the simple mechanism, it should work on all trackpads, or even a Magic Mouse. To zoom in the maps, simply use the pinch gesture. Inertial Scrolling works on the Mac, as well as on other operating systems that supports it natively. There are additional options in the options page, together with a small embedded map to try out different configurations. Supported maps providers:

Google Maps
MapBox
Esri ArcGIS
Apple MapKit JS
OpenStreetMap
and a few others

Happy mapping! ---
