    In extension to @tak3r's answer and @Doug's comment:

    Inline scripts need to be changed to external scripts.

    Move:

    <script>
  chrome.tabs.executeScript(null,{
    code:"document.body.style.backgroundColor='red'"
  });
</script>

    To a new file called main.js and remove the <script></script> tags

    Include the following in the <head></head> of your HTML

    <script type="text/javascript" src="main.js"></script>
