I am having a lot of trouble on Facebook

http://bestpozitiv.ru/video/stoj-do-kontsa-i-ne-vzdumaj-slomatsya/   This is my problem and I am coming to you for help.  For a long time now I cannot use IE on Facebook to upload, share or download.  Now, I can't view a video.  From what I was told it had something to do with Norton and Facebook apps.  I'm not sure how to address this.  I have been trying to watch this video that was posted on FB.  I tried IE and Firefox and can't with either one.  One of the people that commented to me about it fixed it will Norton.  Where do I begin?  The video posted at the beginning of this.  As said, I was told by someone that also has Norton Internet Security that the Norton tech fixed the problem.  Help, please.
