In the network panel (in FF), I have a structured view on JSON data, and can expand nested objects and arrays (like here <a href="https:&#x2F;&#x2F;mdn.mozillademos.org&#x2F;files&#x2F;7421&#x2F;nm-response-json.png" rel="nofollow">https:&#x2F;&#x2F;mdn.mozillademos.org&#x2F;files&#x2F;7421&#x2F;nm-response-json.png</a>). Same goes for JS objects, which is a thing that bugged me long time.
