Vipin,
Cxense is an ad serving vendor. They usually have a JavaScript file that loads on the page and then serves an ad.
To verify it is working, you can check an Inspector tool like HTTPFox, Charles, etc to see if that js file is loading or check for the ads that should be getting served.
It sounds like you have copied the contents out of the JS file and into an extension. Cxense typically has an external JS file that gets loaded, which can easily be loaded via the Tealium Generic Tag. See this post for a little more information:

If further help is needed, I would suggest reaching out to your Account Manager and they will pull in the correct resource to assist.
Thanks!
