If I call console.log(\'something\');
from the popup page, or any script included off that it works fine.
However as the background page is not directly
You can open the background page's console if you click on the "background.html" link in the extensions list.
To access the background page that corresponds to your extensions open Settings / Extensions
or open a new tab and enter chrome://extensions
. You will see something like this screenshot.
Under your extension click on the link background page
. This opens a new window.
For the context menu sample the window has the title: _generated_background_page.html
.
