first try to remove this part from your manifest file

"content_security_policy": "script-src 'self' https://ajax.googleapis.com/ajax/libs/jquery/1.4.1/jquery.min.js; https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js; object-src 'self'"

then download all of your external links to a local environment folder after that reference it there.

for example download https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js to your parent folder and change your reference from

<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.4.1/jquery.min.js"></script>

to

<script src="jquery.min.js"></script>

and also I recommend moving all of your referencing from head tag to the bottom of body tag.

Your "content_security_policy" has several problems.

1) The first is that you should remove the semicolon between the 1.4.1 and 1.9.1 jquery declarations. Multiple URLs should be separated with a single space only and no other characters.

2) The second is that you are trying to load this script "http://ajax.googleapis.com/ajax/services/feed/load?v=1.0&num=2&output=json&q=http%3A%2F%2Fblog.tax2290.com%2Ffeed%2F&hl=en&callback=jsonp1373953012503" but you never allow that in your CSP.

3) And thirdly, it appears you need to allow inline scripts.

I would change your "content_security_policy" to look like this:

"content_security_policy": "script-src 'self' https://ajax.googleapis.com/ 'unsafe-inline'; object-src 'self'"

'unsafe-inline' should fix the "Refused to execute inline script" error.

https://ajax.googleapis.com/ should allow both versions of jquery to load as well as your /ajarx/services/feed/load URL.

If you build a packaged app, you can not load external script. Your application must embed every scripts, styles or images.

Check this link to ensure you are following chrome app CSP rules: https://developer.chrome.com/extensions/contentSecurityPolicy
