Good plugin but not not work properly with internet download manager (IDM) already installed > start download automatically.

Edit: YES! IDM is poorly written soft lol :D via email i will report this issue to the developer.

Thanks for your help.

That's a poorly written software. It's obviously a IDM bug, so I don't have what to fix.

What happens is that my extension uses HEAD requests to find the file sizes of the video files, so you can see something like MP4 720p (35.9 MB). IDM treats them like GET requests and shows download dialogs.

Could not find the dowload arrow it talks about so I call it a dud.

YouTube Video and Audio Downloader is an open-source project, downloading Youtube videos (using Firefox download manager or a custom external download manager) in all available formats (FLV, MP4, WebM, and 3GP) with video quality of your choice. It also contains a pure JavaScript library to extract the original audio file embedded in video files. MP3 conversion is also possible if FFmpeg is installed. It is also shipped with an offline tool to extract audio files out of FLV videos.

Features:
1. Download YouTube videos in all available format (FLV, MP4, WebM, and 3GP)
2. Extract original audio file. Useful to listen to the downloaded audio files on MP3 players.
3. Download video subtitles in all available languages.
4. Get comprehensive information about currently opened YouTube video.
5. Video conversion tools (mp3 Converter, M4A audio muxer, WebM audio muxer, and AAC audio extractor).
6. Support for DASH video- and audio-only streams with auto muxing.

Supported Video Qualities: 2160p, 1440p, 1080p, 720p, 480p, and 360p

Supported Formats: WebM, FLV, MP4, 3GP, Verbos, and OPUS

Notes:
1. Please install and configure FFmpeg. The extraction capability of the extension improves a lot with FFmpeg installed.

2. To keep the original quality of the downloaded tracks, the extension only extracts the ORIGINAL audio files from video files. If you need MP3 conversion, install https://addons.mozilla.org/en-US/firefox/addon/media-converter-and-muxer/ extension. YouTube Video and Audio Downloader is integrated with media converter extension hence you can access it from the toolbar button.

Firefox 39.0.3 - limiting to 360p MP4 Rated 4 out of 5 stars

(5 stars for the add-on - it's always been reliable !!). Since the 7th August I've noted that in my Win 7 Desktop version of Firefox 39.0.3 is restricting downloads - with only 1 option - 360p MP4. (I've used this to download in 720p - this is now no longer an options). Hoping this gets fixed soon !!

EDIT: 11 Aug - tried on another laptop - no issue. Appears that I may need to uninstall Firefox 39 (becoming a bloated mess !), and reinstall from scratch.

Resolution:Looks like this is cookie/cache issue - suspect that there is a block on this add-on.

This one works when others don't. I only wish that it were possible to obtain higher resolution versions of the video via this extension.

Excellent work, the best downloader I can find! Rated 5 out of 5 stars

have been using for a couple of years I think and it's reliable and convenient! unlike some downloaders this one does not come with ad or other junk software. Well done.

Ottima estensione, permette di scaricare video da YouTube in qualità 360p e 720p! Una volta installata viene aggiunto un pulsante sotto ciascun video di YouTube che consente il download diretto del video stesso tramite firefox!

2015-06-03- Doesn't seem to work in Firefox 38.0.05 Rated 1 out of 5 stars

I looked at the stars given to this (4.5!), and so decided to install it.
It indicated it was installed, but I could not find it in my add-ons. And I tried SEVERAL times!
As well, I could not find its icon beneath the "YouTube icon", wherever that is!
Bah! ONE STAR!

Работает! Помогло, где другие не справились!

Just works! Rated 5 out of 5 stars

This add-on works all the time to download videos from YouTube.

Video DownloadHelper is better, But it fails sometimes on YouTube.

It seems to have broken Rated 5 out of 5 stars

Great program. I know the review guidelines prefer us not to issue bug reports here but I can't find another place to do so. Starting today, it seems to have broken.

You can send me an email to deadline.support@gmail.com and offer more details about what exactly doesn't work. Thanks for your 5-star rating.

A great and easy add-on to use Rated 5 out of 5 stars

Not much to say. It works as it should. No complains at all.

Rated 5 out of 5 stars

Works perfectly for me, thank you!
