Problem solved (for now) - thanks

So it turned out I was paying $40 per year to keep Norton functioning at the 2005 level? Sweet.
Bought & installed Norton AntiVirus 2009, and did Internet Settings > Intrusion Exclusions > unchecked all 3 boxes beginning with "HTTP Facebook." Then went to Facebook and it is now functioning normally.
It has done this before (as I said in my original post), i.e. returns apparently to normal for a short while, then freezes up again; so we'll have to see if this lasts. In the meantime, thanks for all your help.
