Works perfectly! Does everything it should and looks beautiful as well. I have had no problem with SVG images. Wow! Just realised this also defines a global object called json which you can reference in the developer console! This extension is brilliant!

Very usefull extension, I highly recommand it. However, the JSON is formated only when the Content-Type of the HTTP header is of type "application/json". I would suggest to also try parsing and formating the JSON even if the Content-Type is "text/html" for a more permissive debug. Thanks
