I just spent a hour reading about users that that have the same problem that I do.  For some reason we can no longer upload photos on to social media sites.  This is a reoccurring issue.  It comes and goes without reason.  And like most of the other complainers I have no fix nor have I any hope for one.  I have tried IE, Bing, Edge, Chrome and Firefox with the same outcome.  The system freezes.  DOES ANYONE HAVE AN ANSWER!
