It never works on Facebook. Cannot find the frame,..and yes I have clicked on the on/off several times.

Recent versions can not do anything without the "companion app".

O download é feito, mas quando vamos assistir o video, as cores estão fora do foco, a maior parte do video está em preto e branco. Só gastou gigas de franquia, isso quando funciona no Firefox. O que houve? Foi o melhor por muitos anos. Uma tristeza.

DEADLY SLOW

This extension has not worked since the first day, it worked once then stopped and to include the mp4 that did the first time. Will not work on Chrome or Firefox to use on amazon videos for premium or owned Amazon movies. I want my money back or make it work.

Required the installation of additional software and show big banner at result video

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
