Google AdWords Conversion Tag is not showed with Chrome Browser

[alehopgm]

We have installed the Luka extension.

In our test environment it works properly. But after publishing on production, we can't see the tag in Chrome browser, the code doesn't appear at Onepage Checkout Success page when we try with Chrome Browser. If we try with Firefox it works perfect.

We don't understand why is it happening. Any idea to help us?
