This is quite useful and, even though there is the occasional glitch requiring reloading the page or clearing the cache, I think it's worth the 5 stars (and a contribution!).

I would like to see a more detailed description of just how the download takes place (I may unpack the xpi and take a peek).

Update: I had a glitch and contacted the developer - and got a very quick and helpful response. This addon is definitely worth supporting.

And another update: once again I needed to contact the developer and received very, very quick turnaround with helpful information. This add-on has been very useful to me for a number of years now.

Excellent add-on! Great work! Thank you!!

The extension is really good.

This add-on is constantly being maintained and worked. I love that they never let the grass grow under their feet and recognize the need of those who use it. Wish all app creators were as attentive.

This add-on provides just what I need in an easy to use way. I would recommend it to others a lot.

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
