Strangest thing I've run into.  When I log on to our web site via Firefox (ver. 23.0.1) everything there is fine except I cannot see any of the advertisements on the right side of the screen.  I thought maybe it could be that I am zoomed in too tight or it might be a Firefox quirk.  When zooming way out the ads are still not there.  My wife also uses Firefox but she sees the ads fine.  Maybe she has a setting different but I can't find it.  I don't see any settings to block advertisements and even if there was one these are not pop-up ads so I doubt it would work on them anyway.  Does anyone have any idea what might be causing this?
