The Missing JSON Inspector

Inspect JSON in your browser.Inspect JSON documents the way you normally inspect JavaScript objects in the console. Without any ugly decorations or useless features. This simple extension detects when you're viewing JSON documents and allows you to switch between the original document and the JSON inspector via the page action icon that lives in your address bar. The end result is very similar to what you get when viewing XML documents in your browser.

Features (most are configurable):
* Automatically switches to the JSON Inspector
* Keyboard navigation of the JSON tree
* Expand/collapse parts of the JSON tree with mouse or keyboard (hold SHIFT key to include all the siblings, or ALT key to include all the children)
* Sorts object keys in either direction, but can also show data as-is
* Exports JSON data into the content window so that it can be used directly in the console (window.$json by default)
