Nice extension, but it has a problem: it calls for the xml twice. (I noticed it because I was calling my own server, and I saw that my logs server-side were doubled) I suppose the browser is making its own call for the url, and then the extension is calling the same url again.
Yes I know, but it's the easiest way to do it. When the XML is already in the page, it can be messed with by other extensions. I can work on improving that.
