They want money!

não baixa nada e nem instala no navegador

Fonctionnais bien, puis a disparu des extensions. Depuis impossible à ouvrir. Ne fonctionne plus

Rubbish total extortionate rip-off !!

SCAMWARE...

This crap not works after 2 hours, you have to buy download manager

Malware, te pide bajar un complemente adicional.

Doesn't work. I installed the companion app. I have 300mbit/300mbit connection yet it starts downloading with less than 50k/s and a couple of minutes later just stops.

Völlig unbrauchbar - nur mit Hilfe einer Fremdsoftware lässt sich überhaupt noch ein Video runterladen.
Das hat den Namen Add-on nicht verdient -weil es ja eigenständige Software ist.
Ich frage mich wie Mozilla sowas dulden kann - so geht auch ein Stück Glaubwürdigkeit den Bach hinunter.

Absolutely rubbish software!!! Stay away from this. Need to pay extra even just to save a converted file. Isn't this is what the extension supposedly do?! What's the point of converting the video when I cannot save it...
"The easy way to download and convert Web videos from hundreds of YouTube-like sites." They forgotten to add this note: "And we need charge you before you can use the features"

bs bs bs! SCAMWARE. Click bait that merely leads to another required download.

Update Dec-2024. Now they SPLAT a huge watermark taking up 1/6 of the screen ruining your download. Why use their tool if it ruins your downloads? Developers are bonkers. They also hassle you for $30.00 to remove this. You can pick other downloaders.
There are firefox add-ons that are not this intrusive and do not require $30.00US to remove. Look elsewhere.

Do not install this rubbish. Adds horrible barcode to video. Unwatchable! Uninstalled!!!!

Requires an additional app and you have to pay to remove a watermark and may be to listen the audio because my downloaded videos are mute. Why it not clear from the beginning that it is not free?

It was great until it started nagging about this goddamn companion app.
You can take your fucking companion app and shove it up your ass.
Uninstall.

My first (& last) download was damaged because I was'nt registered! You didn't have to force me to register! If it was a good app, I would come for more....

Only detects 5 out of 63 videos in a YouTube playlist. Confirmed useless cos other video downloaders detected all 63.
WTF?
