How do I view the storage of a Chrome Extension I've installed?

It seems like it should be possible to view the localStorage/chrome.storage of Chrome Extensions installed on my browser. I've played around with the Developer Tools a bit, but haven't found a way to do this. Any ideas?

    It is true that stuff saved using chrome.storage does not show up in developer tools, there you can only see stuff saved using regular localStorage API. Do this:

    1. Open your extension's background page by going to chrome://extensions/ ("Developer mode" needs to be checked to see background pages)

    2. Go to the Console tab and type this:

    chrome.storage.local.get(console.log)

    This will spit the whole storage as a JSON object into the console.
