Better than all other YouTube downloaders. It keeps things simple. YouTube now streams separate files for HD video and audio. This addon uses ffmpeg (trusted open source video software) to thread the video and audio together and give you a complete result. No weird registrations required. The plugin parses all the available different video and audio qualities for you to chose from. The only downside is you must go into the plugin options to install the native client and ffmpeg, but that's easy as downloading and running a bat file and pressing an install button.

working good

When looking for a YouTube downloader, you should look for a few things:

1) It's completely free
2) It doesn't require a shady 3rd party executable
3) It doesn't advertise to you
4) It actually works
5) It doesn't access all your data

This is literally the only program that I could find that does all these things. Good program.
(It does require FFmpeg for HQ videos, but everyone should have FFmpeg installed anyway. It's open source and safe)

Took a little while to get it set up (installing the add'l items to DL HD videos)..the instructions aren't great. But once I did, it works PERFECTLY.
