Worthless! Used to be good but now does nothing unless the companion program is downloaded.

Required the installation of additional software for it to work which caused my PC to lock up and crash - not recommended.

Does Firefox read the requirments for this RECOMMENDED Add-on?. I wish there were no stars to give. Video DownloadHelper will not get installed by me.

This terrible add-on comes with a "companion software" that adds a HUGE QR code (watermark) on the top left of videos unless you pay them to remove it. Total piece of crap, I can't believe this is a recommended add on.

NEM LEHET FELTELEPÍTENI NEM ADJA HOZZÁ A FIRE FOX LEGUJABB VERZÍÓJÁHOZ SE

Неудобный, куча каких-то надстроек, просит скачать и устанавливает какую-то свою прибулду, нафиг не нужную.

Cannot detect file.

QR code LOL

Doesn't work anymore. Constantly asks you to install a second "companion" add on and write some Terminal code which I have no idea or desire to do. I just want a regular add on to work regular.

Absolute cr@p! There's hardly any video from youtube on which it works without error, especially if I just want the original size file and not a version in which it has to use the converter and put the giant QR code on it.

Asking for other downloads to work. I have no idea if it is safe to do so

Tut nicht immer Das, was es soll. Es werden ganz andere Dateien und Videos heruntergeladen.

Ja foi bom , além de pedir instalações de programas adicionais ainda não funciona direito. MUITO RUIM

Tempo fa funzionava molto bene. Ora non scarica più nulla .

现在居然还要强行要安装别的合作组件才能下载，不能用浏览器自带下载，真有你的，我选择不用

Do not install it because when it catches a video, it asks you to download another application. Sucks

Tells you to download a "download companion" and still not works: do not install this add-on.
