you have to pay not to have a big watermark on your video, and this is not mentioned beforehand

Doesn't work on Android.

Requires the installation of additional software (imposed service). I do not recommend it.

Пользуюсь Firefox-ом очень давно, года так с 2008 и всегда ставил download helper, хоть и давно не пользовался им. Раньше был очень крутой и удобный аддон, сейчас же это жуткое днище, требующее ещё и дополнительную софтинку (свою же), скачать видео с Ютуба с этим аддоном тот ещё квест, не рекомедую к установке

CRAP - if it has a QR-CODE on the video - then WHY OFFER IT FREE??? JUST CHARGE EVERYONE - instead of doing a BAIT and SWITCH scam! TERRIBLE!!!

Requires payment to remove QR codes it has now just started adding to vids

Need to pay for almost everything.

C'è poco da fare: non funziona. Le poche volte che rileva un video da scaricare non si riesce a capire se sta effettivamente scaricando il video. Penso sia in assoluto una delle peggiori estensioni mai viste: inefficente e con menù pessimi.
0/10

Requires a companion app that is unsecure and cannot be verified free from malware

A Watermark stick on the video, there is plenty of software do better than this

Watermark switch and bait. Not working as advertised. Holding downloaded video hostage after losing 3 hours uselessly "sum" downloaded video - probalby spending it only for adding watermark.

It adds a watermark and asks for 30$ to remove it!

Ужасное "дополнение", ничего не понятно. Функций нагородили немеряно, а толку нет.

Completely useless. Keeps trying to install some additional app on my computer (probably a virus) and even when installed it still doesn't work.

watermarks=trash

The free version is worthless. I tried to download The Phantom of the Opera yesterday. it tool about 14 hours and the result was more than 2 hours of a blue screen with a QR code.

Used to be great: it would just mux the raw content together with ffmpeg in companion app. Now it wants to spend days slowly re-converting video just to add a QR-code watermark!? This change alone took it from a 5-star to a 1-star add-on.
