I wonder if the Private Browsing and Tracking protection breaks this. Did you try it with a normal browser without that?
When reading Cnet Download SW product descriptions by Editor and Publisher I have always been able to use the "read more" button until recently. I use Firefox with Private Browsing and Tracking protection but I am sure that I was able to read descriptions with these features previously. I am not aware of any changes that would stop me from being able to read Cnet info on a product. Any advice would be helpful.
