SaveTube is now returning "videoplayback.txt" for all downloads. It does not matter what video I try to get or whether I try it in Firefox 57 or Waterfox, they all return an empty text file.

Try the ViewTube update below, see if the downloads work. It's the same as SaveTube.

I had been having problems with YouTube recently. This update appears to clear them up.
