Doesn't work anymore. No error message.

very slow download speed ,bad interface and factionality one of the worst app i have use for download

Non è più in grado di scaricare video senza l'installazione di addon aggiuntivo che però non è per firefox, ma si installa direttamente nel sistema. Non mi piace questa cosa, quindi ne sconsiglio l'installazione.

It is no longer able to download videos without installing an add-on, which is not for firefox, but installs directly on the system. I do not like this, so I do not recommend the installation.

Does not work (anymore?) with all web-video, and now makes Firefox freeze on an attempt for recapcha loading on a login-page...

Aplikace k hovnu!

asked to download a companion program on first download video attempt. I don't trust it, That's fishy stuff.

Always demand I add another extension which is not mentioned in Firefox explanation of this add-on. So, I don't trust. Their support page is blank.

Скурвился аддон. Требует "Companion App" устанавливать в ОС, без него не позволяет скачивать. Осталось только удалить.

Video downloader is unreliable. It is a janky piece of software that is not user friendly. It doesn't not download videos seamlessly. It's hit and miss. It fails. I cannot invest in or support software that performs this poorly.

Watermark on videos

It used to be free. Now it forces video conversion and if you don't pay, it watermarks your videos. DO NOT RECOMMEND.

Fue bueno mientras duro. ahora te ponen un qr como marca de agua.

С ютуба не качает. Нажимаю и переход по ссылке для установки какого-то компаньёна.

Need to pay for $30+ in order to remove the annoying 2D bar code in every video you download

Too slow. Eat a lot of RAM and CPU. Add stupid QR code to video. 4 minutes 16 Mb video converted about 30 minutes on quad core 3.6 GHz CPU. And they want 30 USD for this? How about no?

I paid for a lifetime license for the Video Converter back in 2011, and still get those #%^&*%* watermarks on my videos. sure I could buy it again, but why? I already purchased a Lifetime License that does not work. Get your head right and fix this issue or a 1 Star is all you are worth to me. Very Slow Conversions and substandard video quality.

download and covert is very very slow And add shit qrcode to the video frames.

This Video DownloadHelper used to be good. At some point they started to require an companion app and added a water mark to downloads unless the user payed. I don't need it. I have no use for the video with the water mark and no interest in paying them for registering a codec.

This WAS an extension for Firefox. At this moment, when it asks you to install some software to do its job, it's worthless. I won't install anything not approved by Mozilla. Next !
