Have used the free version for a long time so finally decided to support the developer, delete my other similar extensions and do the upgrade (whatever the reason was). Seems great so far.

This is the best you tube downloader and is so simple to use. It puts a download button on all the videos and when you tube change their code it is updated very quickly for a one man band

it's so incredible and helpfull also time saver add-on i like it much

One of the most useful add-on

easy, fast and simple. Just excellent.

worked easily and with very little effort on my part.

Parfait

The downloader I was using borked.
I've just started using Youtube Video Downloader this evening. 720p and mp3 downloads working. No probs.I have not tried 1080p. If it looks good full screen on Youtube 720p seems fine. I'll try 1080p if something looks exceptional and see if it makes a diff.
I'm running Firefox on Linix.

Best YouTube Video Downloader available. I have been using it for years and recommending it to everyone the entire time. I highly recommend it.

Works a treat for me - THANK YOU

Works great and is always updated to keep working even with the big changes that youtube keeps making every year.

estupenda extension

Very clear, easy-to-use add-on. On my very first download I ran into the upgrade wall but that was explained properly and worked well. Unfortunately, I misunderstood originally and ended up getting a Premium YouTube trial, that I didn't really need. If I end up using this frequently, I will certainly make further donations.
Have now been using for over two years and the extension continues to work well. Highly recommended.

Absolutely the best one button download for youtube.
Try it you'll like it .

Great tool for offline viewing. I believe it's worth the small donation ask for. Takes a few days to update when channel changes delivery system. I Don't care, just have some patience.

Muy eficaz. Rápido y sin fallos.

Currently the best YouTube downloader available. Very easy to use. Highly recommended!
