Not what I expected Rated 1 out of 5 stars

Read the little print properly: THIS ADD-ON JUST ADDS A BUTTON ON TOP OF VIDEOS +++IF+++ YOU ALREADY HAVE INSTALLED ANOTHER PIECE OF SOFTWARE CALLED VDOWNLOADER.
And, for what I have read, the software contains spamware. Removed and gone back to Download helper.
Also, check the developer comments, he seems to like to go to other developers products simply to boast about his own add-ons! No comments...
