Spent numerous hours and days looking all over the internet trying to figure out why the photos in facebook will not open when clicking on them in the feed - just black box and the words.. I cleared the cookies on firefox and is updated, and my macbookpro OS 10. 9. 2 Only ones that have an outside link work..you tube or a link to an outside website..
I think there is something I need to update? It just stopped working one day ...
Thanks for any advise
