I am now getting this 'banner warning' when I visit any Stack Exchange site using Firefox. However, everything seems to work fine in Chrome. I use Firefox because IMO they are not quite as bad as Google is, so please - let's not have any suggestions to switch to Chrome. I looked into what settings in Firefox need be changed to allow this ("cross domain scripting"), but I got a tidal wave of documentation which I can't (won't) read & wouldn't understand without a massive investment of my time.
Also, this question has been asked (and sometimes answered) many times here. I would call it a "chronic problem". But it seems that there's not one answer - except that "it depends", which is not particularly helpful. "The answer" it seems, could be one or more of many things - which you will see if you spend an hour reading through the "Similar questions" list as I just have. My firewall blocks nothing when I enter URL
ajax.googleapis.com in Firefox, it goes here:
I'd be willing to make an exception for cross domain scripting from Stack Exchange (which may not even be the problem). But I don't feel it's in anyone's best interests to allow "cross domain scripting" from all sites.
Is there a "prescription" for this ailment in Firefox that doesn't require 'shields down'?
