Have used it for years. It works quite well, in spite of websites frequently changing code to disallow video downloads. I highly recommend this mature, working, safe, reliable add-on. This alone makes firefox my browser of choice!
Update: I've now used it for another year and the active development is a great feature - when a site blocks downloads within a short time Video DownloadHelper is modified and works again. This is great software.

CONVERTED VIDEO LOOKS LIKE SHIT AND THEY ASK FOR MONEY. same as the last review.

Muy buena. Nunca tuve ningun problema.

Sehr gut und einfach zu bedienen. Danke schön!

This app was awesome for years but has not kept up with the times. I'm running latest version but it no longer detects YouTube videos in an MP4 format. You now get a horrible watermark and the quality of the conversion is severely degraded.
