I have just switched from Chrome to Firefox. I can open the same web page in each browser, but only can access and make comments in the news article in Chrome. I am signed in to Disqus in each browser. In Firefox, when I click on the "comments" click point, nothing happens and they do not appear at the bottom of the article as they do in Chrome. I have searched through the settings in "tools & options" but have found no settings that seem to affect the problem. Help please!
