What can you say about something as cool as this other than, "WOW".

Best one I've found so far. Good job

It works well. I usually use it for downloading some interesting videos.

es uno de los pocos que descarga MP4 con Firefox, amo esa extension.

great tool. Probably the fastest one catching up with all the code changes used by youtube to prevent downloads

The add-on can download mp4 and mp3 format. This is better compare with other Youtube downloader. I would recommend to suppor this add-on.

This downloader keeps opening new tabs for its website on by Firefox browser. I'm not interested in the website for "Easy Youtube Video Downloader" . The latest page on their website asks for a cup of coffee. No kidding. No option to opt out of receiving such notices. No way to unsubscribe.

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!
