I've been developing some apps that use jQuery SOAP and receive XML responses from the server, but Firefox insists on showing the XML AJAX responses as plain text in a single line, while only JSON is formatted.
Every time I need to debug a response, I have to copy the entire output and paste it into an XML formatter tool, which is far from the most straightforward way to debug.
Chrome, on the other hand, formats both JSON and XML (and possibly other response formats as well).
Please consider adding a parser to pretty-print XML responses. Firefox Developer Tools have historically been better than Chrome’s, but the lack of XML formatting is extremely frustrating.
