The DOMInspector keeps track of all the windows that are open—all the DOMs that it knows about—so to access the DOM of a particular window in the DOMInspector, simply access that window as you would normally and then choose it from this dynamically updated menulist in the DOMInspector application.
When the DOMInspector loads a DOM, it populates the left pane with the structured, hierarchical view of the DOM and the right pane with information about the selected nodes, including attributes and their values and other data.
Once you have the DOM of the page or chrome you are interested in, you can use the tree view in the left pane of the DOMInspector to find and inspect aspects of that DOM you are interested in.
