IME this is the most reliable media downloader of the lot and I've tried at least 20.
I'd use it as my default if it could directly DL audio without lossy transcoding (eg going from say, *.m4a to *.mp3 instead of retaining the original file format).
If you don't care about a barely perceptible loss of quality, which most won't even hear, this is fine.
The only time it regularly fails for me is with streaming Ebay vids which again most people won't be downloading to begin with. (They're made from scores of ~100k *.m4s files which need to be concatenated using ffmpeg). 5*

Wow! This little thing is actually working. Finally I'm happy.

Many thanks for a downloader that actually works - and works well :)

This application works real good with very few failures. I'd recommend this application!

This is a really well designed add-on that rarely fails. It stays quietly out of the way when I'm not using it and it's not busy gathering personal data. Thanks for all the hard word
