Garbage, requires you to download and install software to use.

Need an additional add on to download videos, which is not a problem, but the problem is, the nice big QR Code in the lower left hand side. I downloaded a Japanese video to practice listing and reading Japanese and the QR code watermark covers some of the Kanji/Kana.

It is absolutely asinine that they put a QR code watermark on downloaded videos here. Greedy authors are trying to get a payday on something that has been effectively been free on the internet for years.

Embeds a spammy QR code into the video

This used to be good until they went and slapped a huge QR code to the videos you download. Going to start using online downloader/converter tools from now on.

tem que pagar

this isnt even trial version, the QR Code watermark is HUGE

This add-ons is not free, will show a huge barcode on the video unless you pay.
say this on the start instead of wasting my time installing the add-on then installing the companion app to find a giant barcode that cover 30% of the video

heres a QR CODE that is GIANT on the downloaded video! Woaw!

Qr-code covers a vast part of the video, making this add-on useless

Now requires an external executable to be run on your PC to use. It's been flagged as a Trojan. Don't use this extension anymore.

water mark...

Been using this for years now until today. There is now a huge qr code plastered onto downloaded videos.

Been a nice ride, but now is worthless.

WARNING VIRUS AND QR CODE PAYMENT RANSOM

The downloader does not work on YouTube but says you need the companion app, fair enough so I download it.

It then adds a MASSIVE QR Code which you can only remove by PAYING for a license, this is a breach of Mozilla rules.

So I tested the companion download on VirusTotal plus some other sites.

The result says two sites found malware called W32.AIDetectMalware
VBA32 & TrojanDownloader.Private

So I test elsewhere and get this description for above

f-secure.com/v-descs/trojan-downloader.shtml#

this type of trojan secretly downloads malicious files from a remote server, then installs and executes the files.

No way I am risking this, there are other video download apps

Unusable because of the qr code. Disappointed.

This extension has been broken forever. It can't download anything at all.

Place a massive qr code in the corner. ruining any video taken unless given money not worth it also cant dowload audia without giving em money
