Given a Chrome extension that sets up a browser_action based on a default_icon click, how can that extension print to the console? For example, say my manifest.json includes this:
{
  "name": "Testing",
  "version": "1.0",
  "browser_action": {
    "default_popup": "testing.html",
    "default_icon": "icon.png"
  },
  "manifest_version": 2
}
and my testing.html loads a <script> with some Javascript:
console.log("WHY DON'T I SEE THIS??");
Why doesn't this print anything to the console? And how might I go about getting something printed to the console?
