This plugin works like a charm, and the developer obviously keeps on top of the constant changes at YouTube. I've never had a problem with it, either, and I'm pretty nit-picky. Kudos.

it works great and all, but the mp4/video part stopped working it says its been disabled when i try downloading a video. UPDATE: hey when are you gonna fix this button disappeared again i love this addon but keeps disappearing and downloading is an issue and its been about well almost a week 1/2 to be exact if you can pls keep this from happening again pls and what if nobody has money to upgrade or donate to you

Still the very best and most easy to use

So far the best youtube downloader I've ever known and tried.

This application is basically free and it has worked many times for me. It only stops working when YouTube makes changes to its code to avoid, among other things, people downloading videos. The person working in this application does it all by himself and offers it for free. He is constantly updating it and fixing bugs. So why not give him a good review?

Excellent! Would like to rate it 6 stars.

Best Ever!!!!

EDIT: Unfortunately this once great extension is now defunct. The author doesn't seem to keep it updated anymore. Don't bother with this. Grab "Video DownloadHelper" instead.

The best youtube downloader extension, period. I'm a tabletop RPG GM and I use music from video games for my sessions a lot and the music is hard to find sometimes. So it's easier to just go on youtube and do the conversion myself. The person maintaining this extension is very diligent in updating it too. 5 stars!

I like the add on. a lot

Absolutamente formidável. Fácil acesso ao download e muito prático.

Easy to get, easy to use. No problem. A perfect tool always struggling with Youtube numerous changes.

Δουλεύει τέλεια

The author is constantly updating this add-on to keep ahead of YouTube's frequent code changes. This is a very well maintained add-on.

It's very good
