I have a fairly new ACER PC running Windows 8.1 and employing Firefox (31.0) as a browser. Last week something odd happened. There are many Fox Sports websites that I regularly visit and comment on the story content. All of a sudden, none of the comments, mine or others, were appearing when the pages open. Now, entire stories are not showing up. This is not the case when I access these same pages on my laptop (Windows 7, same browser with identical add-ons). Any idea on why this might be happening?
