No matter whose responsibility it is to fix, do you want to wait for it to get fixed or see if changing the settings or disabling the AOS will be a workaround until then.
The online.wsj.com home page loaded almost instantly. But, yes the wsj.com is very slow when choosing articles/links from that page even with the items in the Do Not Track section unchecked. So I would try disabling the AOS add-on in firefox.
What other security based add-ons do you have installed or ones that might interact with the avast online security add-on ?
