News outlet JQuery code works in Chrome but not Firefox

News outlet JQuery code works in Chrome but not Firefox

The following JQuery code is from a "news" outlet, The Daily Caller. A click on a graphic invokes a Disqus comments section to any Daily Caller article.  It works in Chrome, and it used to work in Firefox, but now It does not work in Firefox ESR 38.8.0.  I don't know what I might have changed in Firefox.  It is not my code.  It appears to be something in Firefox's runtime / add-ons.

Do you have any idea what may be going wrong?
