UserJS: YouTube Video Download Button

 This script  makes a download button for videos on YouTube. It also shows available qualities.

Best to use together with this script.
There are two versions: one for old Opera 12 and another for Firefox . I still use the old Opera, so the script for Opera is better tested
YouTube Video Download Button:
Download  for Opera 12
Download  for Firefox version


Save the script in unicode.
