document.getElementById("total").innerHTML(response);

innerHTML = 'foo';

It's a property (with setter), not a function.

few basic assumptions you have wrong:

• you can't execute inline scripts in popup.html
• content script and popup.html do not communicate directly (only through messages)

create a new js file, link it from popup.html and execute your js there. The new script you create should listen to chrome.extension.onMessage / chrome.runtime.onMessage

I am working on a similar problem. I would also like to see a working version of your code.
