• Component: Web Inspector (Deprecated)
• Status: RESOLVED DUPLICATE

===========================
What steps will reproduce the problem?
1.  Make an Ajax call
2.  Go to Developer Tools > Resources > XHR Tab
3.  Select the resource on the left

What is the expected result?
If HTML is returned (say a 500 status is returned along with HTML output from your particular web framework) there should be a tab to view the HTML rendered with the browser.

What happens instead?
The best we have is the Content tab, which has the HTML in it's raw format.  To effectively read the result from the server, one has to copy the raw text, paste into a text editor, save the file, and then view the file in the browser.
===========================

For HTML content we could provide a "Preview" tab with the generated iframe inside.

Hi, I'd like to attempt a patch for this, though I'm afraid it might take more work to review than for me to write since I'm unfamiliar with the codebase. Just let me know if that's the case.

I've attached a simple patch that works for my use cases. There are a bunch of questions inline starting with "// PATCH".
