This is a bug report.

**Expected Behavior**
React should not suggest me to download the DevTools extension in a `chrome-extension://` page, because the extension has no permission to inject the devtool.

**Actual Behavior**
`Download the React DevTools and use an HTTP server (instead of a file: URL) for a better development experience: https://fb.me/react-devtools`

**Reproducing**

1. Create a Chrome extension with an `option` or `popup` page that uses React
2. Load the extension to Chrome and open up that page.
3. Observe console.

**Version**
Google Chrome 56.0.2924.3
React 15.4.0

'with ReactDOM.hydrate() if you want React to attach to the server HTML.',
        );
      }
    }
    const newRoot = DOMRenderer.createContainer(container);
    root = container._reactRootContainer = newRoot;
    
    DOMRenderer.unbatchedUpdates(() => {
      DOMRenderer.updateContainer(children, newRoot, parentComponent, callback);
    });
  } else {
    DOMRenderer.updateContainer(children, root, parentComponent, callback);

  return DOMRenderer.getPublicRootInstance(root);
