It worked wonderfully. But then I made the mistake of purchasing the upgrade, and now, most of the videos on youtube are not even recognized by the app. If you want to keep using it, use the free version. But don't waste your money by "upgrading", you will be really disappointed.

depuis la mise à jour de décembre l'app détecte les vidéos mais il est impossible de les télécharger, il y a toujours une erreur. j'ai essayé en navigation privée ou non, en mode j'accepte tous les cookies ou non, avec le plus de confidentialité ou avec zéro, elle ne fonctionne jamais. scandaleux

Simply put it doesn't work. I tried it today (March 11th 2026) and wasn't able to download anything...
UPDATE: I tried it again today (March 17th 2026) and wasn't able to download anything...
So it's easy to conclude it's still not working...
I checked with (2) friends in the US who bought the paid version and they tell me it's not working either as of (March 17th) today...
No way would I pay (what is it) $30 for a downloader that isn't working...

no function! Firefox 148.0.

Doesn't work on Firefox 115.32.0esr

1 star because it now - shareware software.

I give it 1 star because it can not be given 0, no download, it forces you to spend 2 hours to continue downloading, sometimes it stops working and does not look for media, apart from that it forces you to go 2 hours without being able to download anything, does not download absolutely anything, stays in 0%, and in addition, it does not show format only audio, another thing is that you only depend on that you look for the videos automatically instead of putting an option to write the URL of the video, I am interested in

Was working before I paid for premium, now it doesn't work at all despite following all the steps to correct this.

Always says "Waiting for media..." and cannot download videos, even when you force media detection. In other words, doesn't work at all.

Ancienne très bonne extension devenue payante. Il faudrait le mentionner clairement dans le descriptif de l'extension.

Obtenu un semblant de virus à cause de cette extension.
Après avoir tenté de télécharger une vidéo sur rokfin.com/, l'extension a téléchargé très rapidement un fichier .mp4.
Sauf qu'après avoir ouvert le fichier .mp4, avec VLC, aucune vidéo ni son ne se charge. Alors après l'avoir fermé, et tenté de supprimer le fichier, un message d'erreur de ce genre est apparu : "impossible de supprimer le fichier, car il est déjà ouvert dans un fichier jmpeg.exe".
"jmpeg.exe" n'est peut-être pas le nom exact. Je me souviens juste que ça portait un nom d'image avec un .exe à la fin.
J'ai du utiliser le gestionnaire des taches pour arrêter le programme "jmpeg.exe", et ensuite supprimer mon fichier .mp4.
Pas vu d'autre symptômes de virus après avoir fait une analyse complète de mon PC par windows defender.

Used to be great but now wants me to wait 2 hours in between downloads or pay 30$. POS like the rest of these types.

2 downloads to then force you to wait 2hs for the next makes the entire purpose of an addon like this useless.

with newest update: when clearing file list, downloads are also deleted. Not acceptable at all. Obviously the author wants to sell the full version by making the free version unusable. This add-on should be deleted from the mozilla site. JDownloader 2 does the much better job for free. Available for Win and Lin. No "compagnon" app needed.

You need to pay a premium for something yt-dlp does for free.

To download in 720p, do I need to be PREMIUM? That's a joke.

I prefer to use the website app.ytdown.to, where I download ALL resolutions for free.

It completely breaks YouTube and other sites, changing the original format that can be downloaded to “TS” format. On YouTube, it becomes impossible to download videos in “MP4” format. Since I disabled this extension, everything has returned to normal. I ended up installing IDM (Internet Download Manager) Premium, which is faster and integrates with Firefox. I do not recommend VDH, especially the paid version, which is completely useless since they removed the file conversion feature that existed before.
