It's a scam. It may download files, but in formats it can't play. It demands money to convert them to a playable format :3

I simply downloaded the extension to install a youtube video as an mp3 file, easy enough. After opening the application and trying to do so, I was then prompted that I needed an external application to even do that... Okay, sure. I install the external application (which no other firefox extension has ever required from me?) and tried again to download the mp3. I was then prompted that I needed a $30.50 arbitrary subscription to do so?? I Was only told this AFTER I installed the third party application. That was annoying, but whatever. I decide to just download the video as an mp4 and manually get the audio I need, because seemingly just mp3 is a premium. I was then told AGAIN that I needed a subscription to do so as well??? This application does absolutely nothing unless you pay the author an exorbitant fee, which is never clearly disclosed to you. This extension is straight up predatory and dishonest as it doesn't make it CLEAR to the user that they 1. need an external application to do certain things and 2. doesnt up front tell you that you need to PAY to use it until you conveniently already have the application installed.

There are plenty of other free alternatives out there to do the same thing. Uninstalled.

It recently started blackmailing me to pay 20 euros otherwise a huge QR code covers like a quarter of the video. Totally useless now.

Yes

j'avoue que j'ai hésiter mais maintenant je suis convaincu. il est simple et bien intégré à firefox

this is as good a downloader as i have found, it does what's needed without any bells or whistles. Good stuff!

I like this plugin. I am using it for many years. It has a good and not so good days, but lately it works very well except some YouTube videos are not downloading.

What I would like to see, automatically add YouTube video ID at the end of the file name. At least make it available as an option. It will be great. In some of the older versions you had it, but it is missing now.

Thank you for this great add-on.

A very useful and super easy tool for downloading videos!

Merci à toute l'équipe pour la création de cette extension vraiment très utile et efficace de surcrois. Du lourd !

exélente application , telechargement de qualité , et fort pratique §
