I am building a firefox toolbar for one of my websites. The site allows you to create your own lists, and this is done using ajax and the XMLHttpRequest.
I have set up a firefox toolbar and want to have an addEventListener which listens to see if the a web page calls XMLHttpRequest and I need to be able to parse that url, so I can dynamically update the toolbar.
Does anyone know how I can do this? The only help I have found so far just reads the doc.location.href on a page load, and that is not what I need.
