Developers want to see the HTML response of HTTP requests in a formatted way to be able to easily read the contents. This is especially useful for error responses, which are not output on the website.
This is a follow up for bug 1211525 It should be possible to preview XML/HTML HTTP responses as nicely rendered markup (inside the Response tab). Honza

Removing that feature from the network tab was really frustrating. Debugging API errors from Django got a lot harder since 500s come with a HTML stacktrace (when debug is set to True). That should facilitate development but currently is actually making it harder since we have to copy the HTML from the Response pane into a .html file an then open it.
