Whoever is administering this site, needs to take a long, hard look at the CRO software they're using from sumo.com. The reason being, that it's rapidly becoming so much of an annoyance, with respect to "Page Unresponsive" dialogues popping up in Google Chrome, that it's now one step removed from denial of service attack malware.

Plus, even an elementary examination of the developer console, yields a frightening catalogue of errors being generated by the page, including forced reflows, event handlers requiring frankly ridiculous amounts of time to execute and triggering violations, but the sumo.com code compounds this, by launching a continuous chain of setInterval() JavaScript calls, that all result in execution time violations, and start impacting the browser's performance in a serious way, if you let this code run for more than about 15 minutes.

You might want to ask yourself some serious questions, not only with respect to the sort of data that's being slurped from the site and sent to people no one in their right mind would trust, but with respect to the fact that their code is bringing your page to its knees. You need a far less invasive CRO system in place.
