I usually download high quality 480P for merging. This one is really helpful!

It does not show the video size. For example I want to download a 320x240 size for my phone, but I can't - it is not shown.

Best YouTube Video Downloader, but not perfect. Rated 4 out of 5 stars

This beats other YouTube video downloaders hands-down. It works, it can get you the highest quality audio and video (which for some unfathomable reason YouTube separates so they have to be downloaded separately and combined with FFMpeg - which this add-on does automatically), and there are no annoying ads.

I would give this add-on 5 stars if it weren't for a few issues.
1) Since the latest update the download button doesn't show up unless I refresh the page.
2) Even though I set my default video quality as 1080p, I still have to choose the video quality every time I download a video. It would be nice if there were an option to download the highest quality video and audio automatically when clicking the download button.
3) When going from one video to another, if the download options are already open they will still appear on the next video, but not apply to that video.
4) Some of the options say "video only." This is confusing since it actually means that the add-on will download the video and audio streams separately and combine them, not just the video by itself.

And it would be awesome if a batch download feature was added.

Great downloader for high end video

Богатейший функционал при потрясающем удобстве Rated 5 out of 5 stars

Первое дополнение для скачки с Ютуба, которое у меня, как у жуткого гика, не вызывает нареканий по функциональности. Наконец-то можно не париться с самостоятельным объединением видео- и аудиопотоков после скачивания. Это несложно. Но задалбывает. Отдельный плюс - за использование православного ffmpeg, а не самопальных поделок на коленке.

Но самое главное - даже не эта навороченность, а... как ни странно, чрезвычайно высокий показатель юзабилити. Всё сделано очень удобно для простого пользователя, и в большинстве случаев - однокнопочное.

В общем, браво!

P.S.: это первое расширение, которое настолько круто, что замотивировало меня оставить отзыв.

Used to Work Rated 4 out of 5 stars

It doesn't seem to work with Firefox 37.0.1. It used to work before the update. Can't find the download button any more in youtube. It used to work very well. Please update to be compatible with version 37.0.1.

Using this addon for a little time, yet it has proven its efficiency amongst all that kind of "youtube downloader addons". It's very handy, simple and terribly fast, covers a lot of formats and also serves as a format converter for any local video/audio file ; that too is amazingly well done, you can even fusion audio and video files.

I had some compatibility issues with music .m4a files from this addon with certain programs, and just had to drag the file into its converter (ffmpeg installed) and it gave me a variable bitrate .mp3 file in the same folder the second later.

Very recommended if you like to keep some Youtube videos locally and are into 'underground'music that's not necessarly available everywhere and the authors don't give download links for their musics.

The addon can even be used as a fast and efficient converter through your browser if you need so.

I have used a lot of "youtube downloaders" kind of addons for FireFox over the years and I had to register an account and make a review because this one is by far the best I ever had. As I said, it's efficient, simple and fast. It's light and as far as I know doesn't contain any ad, and we better hope it will be kept up to date for a very long time and doesn't become like others losing its charms while gaining heavy ads and annoying added steps for one thing.

So I give it a 4/5 stars. Perhaps nothing is perfect but it's actually mainly because I don't have enough of knowledge into video and audio files to make a judgement on this. All I can say is that I wouldn't drop it anytime soon nor come back to another addon, it met my expectations and even more.
