Rated 4 out of 5 stars

simple, nice and clean user interface.
But there's no option to download 1080p although the video has 1080p format.

The 1080p should be in the second page (video-only streams).
If you have FFmpeg installed, the extension will download proper audio file as well and combine them together.

AWESOME!!! Rated 5 out of 5 stars

AWESOME YouTube Downloader. After contacting Dev, I now know that it can integrate with dTa (DownThemAll!). For that reason (and many others) makes this Addon THE ABSOLUTE BEST YouTube video downloader for FireFox. I used DownloadHelper before, but this Addon is FAR SUPERIOR, and an absolute necessity for anyone who want to download YouTube videos to watch later.

You can integrate it with dTa!

download button in the way Rated 3 out of 5 stars

a good addon
some options don't work right
options page needs some work
can't move or remove download button that blocks titles of videos

This review is for a previous version of the add-on (0.3.4). 

I added a new option for disabling the download button.
Try version "0.3.5b3"

If the button is disabled, then you need to use the toolbar button for injecting menu.

I'm not understanding how to use this, I suppose — an earlier version worked differently (though I'd installed my own ffmpeg, and this version insisted on several new installs of ffmpeg, so yes, it's probably user error). But I'm putting the review here (still 4 stars!) because I think there's a new learning curve. I no longer get a video or a song; NOW I get a link from which I can download 2 "video-author-DASH.m4a" files sitting on googleservers? And from that, I have to save and recombine the sound file and video file on my own. (I indeed like having an mp3 or sound file separately, but I used to just strip it on my own.) This is different that the previous version. I'll put time into figuring out what I'm doing, but I knocked a star because of learning curve only. I think I liked the older interface better. (I've waited a while to write this review -- again, not a bug report, but a review of this new version I've downloaded.) I wish I would have kept the OLDER VERSION, so this is a review, and not a bug report.

If you respond that you added options I just need to figure out, or you had to work around (yet another) YT change, that's fine -- believe me, I get it. Regardless, you still get 4 stars at least for the best quality downloads I've tried on several programs/interfaces/OSes (phone apps, Win8 apps, linux apps, other browser plugins) — this is an AMAZING addon. I just liked the older (and to me, simpler) interface better. To me, this is still a donation-worthy add-on even with the interface changes; I find downloading and watching YT videos far preferable to watching them on YT!

This review is for a previous version of the add-on (0.3.4). 

If you already have FFmpeg installed on your machine, just go to the settings (Firefox -> add-ons -> YouTube Video and Audio Downloader -> Options) and set "FFmpeg location" to point to your own FFmpeg installation. If you do this, the extension will generate a single video file from those "- DASH" files.

Note that when the extension cannot find the FFmpeg, what it can do is to download video-only and audio-only streams without combining them.

No mp3 option Rated 2 out of 5 stars

I downloaded this because there's supposed to be an mp3-download option. Seems though, there is none.

It works Rated 5 out of 5 stars

This appears to be best downloader available at the moment, most of the other developers are giving up, probably due to Google's constant changes.

One small request: would it be possible to disable the bright orange download link on the page? All I need is the toolbar button as the orange really stands out too much.

Rated 4 out of 5 stars

Very happy with this addon, great work! If or when dev updates it, giving users the option to uncheck for undesired formats and the such, it would become even better. Feature request from my side would be an option to set custom download-buttons all together with for example "best audio available".

SUPER ADD-ON Rated 5 out of 5 stars

It works flawlessly. It's the only YT downloader I use. But like Dun wrote, it would be nice to be able to limit which formats are displayed on the links menu.and to have a hotkey for Audio only downloads. And I know the following might sound petty and ungrateful, but, the color scheme of white text/orange background is a little hard on the eyes. And your toolbar button's text takes up too much real estate. Why not just Initials: YT VAD. That way you would seem hip like all the kids these days. IYKWIM. But, Thanks, either way.

It work. Rated 4 out of 5 stars

Yet, some more option will be appreciated:

An option to select which format will be display in the download list.
A direct to mp3 downloads option.

And this will be perfect.
