Simply awful. I can no longer download uTube music videos. I am using latest Firefox 64 bit version (57.0.2) and latest VDH version (as of 23 Dec 2017) running under Windows 10. I have used VDH for some years, and it used to be a handy add-on, but no longer.

I've had enough of the time-wasting excuses. This product is no longer competent and I'm looking for an alternative.
