Not only are there a lot of videos it can't even find. Sometimes when I log into Facebook, this addon jumps to a video I viewed, and downloads it, even when I do not want the video and I have to stop it. And when I try to go to my FB home, it won't let me! I am forced by this thing to close the window and log into FB again! I hate this addon! I am uninstalling it right now, and good riddance!
