问题
I'm trying to debug a Chromium extension with console.log(), but I noticed that nothing is appearing in my JavaScript console. I assume the console object for the extension is not the same console that the document has access to, so how do I dumb a variable into JSON so I can see the result. I'm looking to get something like console.log() with Firebug.

The default Javascript console does not work for extensions, in order to see the console for the extension, you have to:
Right click on the Browser icon
Click Inspect Popup
That window has the Console for your extension.
