Nice addon. But I think you should integrate it with firebug. Because normally we use JSON format in AJAX request, and firebug can display the JSON data but not in color formatting. So you addon integrated with firebug can make developers life easier. :)

This review is for a previous version of the add-on (1.2). 

Have you chatted up the Firebug developers? Could be they're willing to add this sort of functionality.
