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

google-chrome, google-chrome-devtools, google-chrome-extension, local-storage

Solution

I will proceed to amalgamate the existing knowledge present in several answers, into a simple and comprehensive one. If you vote up this one, please do the same with the ones from @mwkwok and @chaohuang.

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:

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

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.
