Used to be a great add on, but now it slaps a watermark over your download that covers 25% of your video rendering the video useless. In addition they force you to install a "companion app" that is full of spyware on your pc to even get it to run. Bait and switch. Dirty business practices. False advertisement. Spyware. How is this even allowed on the add on store? My favorite part about the add on is how they give this huge long story about why they were suspended from PayPal. I mean, seriously, you're surprised about this with the way you operate?

a Extensao funcionava bem, aí atualizou e agora só dá erro GLIBC_2.27' not found no linux ubuntu

Extension is completely unusable without downloading a separate app and paying for registration. Bait and switch garbage. I'm convinced most of the five-star reviews are fake.

contains a watermark after download / enthält wasserzeichen nach dem herunterladen

Used to be a good and fast downloading tool, now it forces a user without a license to wait ages for so called aggregation phase, which is there for burning the license QR code into upper left corner of downloaded video.

这玩意真的能用？下载时断时续，下载完还要合并很长时间，还总是合并失败。

When you ask it to download a video it says you need to download a "companion app", don't fall for this...

Used to be great and would download completely and quickly. What is this thing called aggregation that can take hours!? It renders this plugin useless!!!

Requires additional software to work... No thanks.

Wygląda na oszustwo, więc dziwię się, że ma oznaczenie "Polecane"! Dodatek wbrew opisowy nie ściąga filmów tylko wymusza zainstalowanie zewnętrznej aplikacji, która zawiera złośliwe oprogramowanie. Co więcej nawet po zainstalowaniu aplikacji filmy wprawdzie się ściągają ale mają wielki znak wodny, którego nie da się usunąć jeśli nie zapłacisz $30 za wersję płatną.
I oczywiście nie ne ten temat nie ma w opisie dodatku, dlatego moim zdaniem jest to zwykłe oszustwo i powinno być usunięte nie tylko z polecanych ale także z dodatków w ogóle!!!

EDIT 18/07/2026 : toujours aucun changement, VDH ne détecte plus aucune vidéo malgré la licence, je descends la note à 1 étoile, car on ne peut pas mettre 0 !! Je ne comprends pas les internautes qui mettent 5 étoiles alors que VDH ne fonctionne plus et n'est plus mis à jour.

EDIT 30/05/2026 : depuis plusieurs semaines, plus aucun téléchargement possible sur YouTube malgré ma licence achetée !! Je baisse à 2 étoiles.

EDIT 12/01/2026 : dommage que Chrome "bloque" les téléchargements, sinon sur Firefox, ça fonctionne plutôt bien.

EDIT 05/12/2024 : j'ai du acheter la licence pour pouvoir retirer cet affreux énorme QR code !

ORIGINAL EDIT : cela fait près de 2 ou 3 ans qu'il ne télécharge plus aucune vidéo, ou bien un fichier mp4 de 1ko, le companion ne sert à rien non plus.

***CAUTION!!!***
I confirm negative reviews about watermarks - when you use it only few times everything is ok, but after some time big watermarks start to appear at your videos to force you to buy addon. Please DON'T LISTEN positive reviews and DON'T DOWNLOAD this addon.

so bad

Does not work without downloading a separate program.

Doesn't download anything until you download and install a third-party app. This information not in the descripiton. The app installer "VdhCoAppSetup-1.6.0.exe" contains SecureAge APEX ! MALICIOUS according to virustotal: https://www.virustotal.com/gui/file/4d1bfc9dbbfd472f477d7d74ebba7f21b684ef4919cc0e853a6c799936f67216/detection
The extension wants many permission for example own data which include NAMES and PASSWORDS. Using a big watermark which also not in description.

Makes you download a program, and leaves a big, ugly watermark that you have to pay $30 to get rid of! Garbage.
