This is a tool for opening JOSM from arbitrary maps. It works with Leaflet, OpenLayers, and Modest Maps maps consuming XYZ tiles (like MapBox, Stamen, etc), as well as Google Maps (not MapsGL).

How it does this is a matter of extreme hackery; it detects and consumes tile URLs, and then constructs a bounding box from their coordinates.
