Ainda dá muitos problemas apesar de se informar o autor sobre os problemas, eles persistem sem alteração.

False Promises ... Covers the video you downloaded and asks for payment AFTER u already downloaded !!!!

need extra app installed, barely works lately and now video have QR code need to pay to use

with extra app and licence needed...I mean, really?!

it downloads from YouTube with a huge watermark

Requires paid converter to remove watermark

Can't download anything without adware installed to pc

Dishonest - buying a license will stop ability to download from YouTube. Before purchase of license, it allows download from YouTube (with a large watermark). This bait-and-switch is intended to sucker you into believing the tool will work once you give them your hard-earned cash. If they were honest, they would prevent download before the license purchase, to show exactly what you could expect from this extension.

Bullshit. Doesn't download from youtube. Useless.

一々QR付けるな！要らんわ

Has a massive watermark that now makes this extension useless.

It ask you for a license to properly download.

It was a good add-on until they blocked a quarter of the screen with a QR code to beg for money. It is now useless.

Doesn't work!

This add-on is garbage. Used to work great but now it lets you download a video or two and suddenly the companion app stops working or cannot be found requiring it to be reinstalled. Not worth the hassle.

Mozilla really do need to remove this extension from the "recommended" section. Or even remove it altogether at this point.
It used to do exactly what it says on the tin, but nowadays it adds a large watermark in the corner of every video you download. If you want to remove the watermark you need to pay $28.50.
Paying almost $30 for a video downloader is ridiculous. If you already have this addon installed and you're reading this review, remove it immediately and find an alternative.

War für lange Zeit ein super kostenloses Add-On, aber seit die riesigen QR-Codes in die Videos geklebt werden, ist es schlecht zu gebrauchen. Wasserzeichen ist viel zu groß. Damit sind Videos kaum richtig zu betrachten. Macht es kleiner, wie vorher.

Had to drop this after the watermark thing. Makes downloading pointless.

Would recommend JDownloader 2, which works on many of the same sites as this does, and doesn't add any watermarks blocking 1/6 of your video.

Failed to download a video from youtube

No longer free, now a paid product. Massive opaque watermark (QR code) in the corner that requires purchase to remove. I wouldn't even mind buying it if were say $5, but they are asking for $28.50, simply outrageous. There is also nothing on the info page that tells you this before hand.
