Bravo pour cette extension, et son developpeur qui réussit régulièrement à eliminer les obstacles au téléchargement mis par YouTube !

This add-on is good only if the video you want is already cached. If it's not, then the download is extremely slow and unreliable.

If you want to download a video which is not already cached, and you want it in 720p or 1080p quality (or you want the audio in MP3 format), then you have to pay for the Pro version, which I did.

I paid $30 for the Pro version. However, it is only after you pay that you find out the software doesn't run on your computer; it runs on the developer's server, which is extremely slow and unreliable.

The add-on's home page states "Direct video download links from Youtube servers for maximum speeds coupled with instant high-quality (192kbps) MP3 audio downloads at blaxing fast speeds without leaving the Youtube website", which is an outright lie.

To download a file that is not already cached, the add-on instructs the developer's server to download ("fetch") and transcode the video, and then (if the stars are perfectly aligned) you'll be allowed to download the file from the developer's server.

As I'm writing this review, I'm attempting to download a video with a length of 1 hour 51 minutes. It took 33 minutes for the developer's server to "fetch" the audio stream and the 1.8 GB video stream, then it took 3 minutes to transcode the streams into a file, and the add-on has been sitting at "Conversion completed, loading file..." for the past 31 minutes. If this is like my past attempts with other videos, it will sit here forever and I'll have to close and re-open Firefox, clear the browser cache, and then try again (and hope it works that time).

I sent a support request and asked if there were any way to get this add-on to download and transcode the videos on my computer instead of on the developer's server, and the developer responded very quickly, saying it isn't possible. The download and transcoding process MUST occur on the developer's server.

I should also note that when I tried to download one video, the add-on said the video was geo-restricted, so it couldn't download it. I could watch the video without any problems, but because the download occurs on the developer's server, I couldn't download it.

Not downloading in HD

requires payment because downloading hq requires "a lot of servers" . lol youtube-dl has been free forever. should not be Mozilla recommended.

Funktioniert nicht!

Great for grabbing instruction videos and sampling music. Dishita provides great response if support is needed.

bagus banget....

It WAS good. Now it will not download a damn thing.

Cost $$ if you want to download 1080p

No descarga nada. Símplemente, te indica que te hagas "pro" para poder descargar en alta calidad, pero te indica unas esperas inaceptables.

Easy to use and does its work. I'd like , if possible that also the subtitles , in one language , once chosen , could be downloded .

Excellent

I love this app. I use it primarily to download music. It has the option to select 256kb and is very fast.

This is a great add-on. We have very slow internet which makes watching YouTube videos difficult at times, with the video frequently stopping to buffer. By downloading the video, we can watch it without interruption and at a resolution of 720P. The recent update fixes problems after YouTube changed some code to prevent it working. I would definitely recommend this add-on.

One of the most useful add-on! on Firefox and not on other browser. Thank you.

cannot dl mp3 anymore

You have to pay for this extension before you can download anything higher than 360p. Complete garbage.

2021 - doesn't work

can only download mp3 with pro version

This free addon is very good. I am very satisfied with this addon program and the quick support provided. Thank you very much for the work, the support and the development. Highly recommend!
