DOES NOT WORK!
Takes you to a page that says this: Downloading this video is not possible with a Firefox add-on !
The YouTube website contains only an incomplete video adress, so the video can be downloaded only by Youtube itself or by a special program.
Video Downloader Ultimate for Microsoft Windows is such a program and you can find it here. Update: 2025 on a Mac and it STILL doesn't work.

AMAZINGLY OUTSTANDING!!!

outstanding

Stops working.

Very good!

It doesn't do anything.

EASY TO USE, MULTIPLE OPTIONS

It needs to click two time one for video and another click is for audio.
Why don't we get combine them?

VERY GOOD

Very good.

YOU CLICK THE ICON AND GET A BUNCH OF CHOICES TO CLICK ON. UNFORTUNATELY THE LABELING IS VAGUE AND WHAT YOU DOWNLOAD IS HIT OR MISS.
