This add-on worked fine for free before, now it has a giant watermark on any video.

Hot garbage. does nothing special that other video downloaders don't do, and requires an add on to convert video to other formats that immediately asks for money to convert. Probably paid for the good reviews. Avoid.

Firefox recommends the addon. I add it to my browser. I want to download a song ... I am automatically linked to a page and have to download another program to my PC. I think it's a virus, I'm deleting the addon.

But hey, this is Firefox and Firefox recommended the addon - it cannot be a virus. I read the FAQ on the developer side, they look honest. I download the addon again, I download the "program". I want to download a song and convert it to MP3. I am redirected to a page and have to buy a license that costs 19 euros. I am considering buying a license, but I do not get an answer as to how long the license is valid. Okay, I still want to pay. I cannot transfer money because only VISA, Mastercard, American Express are accepted.

Why don't you write this information in the addon description? Look up the term "transparency". What you are doing is a jungle of links and redirects!

It's paid now, what isn't clear when you install.

Non-functional on Firefox in 2020. Asks for Companion App, but till doesn't work after installing it.

You have to install an extra 'companion app' from another source. Very suspicious...

requires to download compagnion app

Данное дополнение позиционирует себя как загрузчик видео с сайтов, однако оно является лишь ссылкой на скачивание внешнего приложения.

This add-on positions itself as a video downloader from sites, however it is only a link to downloading an external application.

The extension leaves a watermark on all the videos unless you pay.

Requires additional 3rd-party software to be installed. Nope!

I wouldn't recommend using this. This will put a watermark on the majority of your downloaded videos unless you purchase a license. The biggest alarm is that this add-on requires you to download an external program (which it doesn't state anywhere in the description). The site claims that it's necessary and provides the source code via github, but no hash to verify it with the source code. Soon after downloading this, I started having some odd behavior with a service via svchost.exe causing high memory spikes, which I had never had since I've installed my OS years ago, and this was the only software I've installed recently in months.

I'm still checking whether the .exe of this addon was the cause, but I would be extremely careful and compile the companion app from the source code yourself if you're set on using this. There's another safer download tool called youtube-dl that is open source, well documented, and free. It's command line only but there's a gui front-end for it that also has instructions to compile directly from the source code.

A letöltött videók minősége értékelhetetlen!! (nem számít, hogy én full-hd-t vagy akár 4k-t töltök le akkor is 320x200- as szintű videót ment le) - The saved video quality is a fucking crap! doesnt matters I'm dowloading a full-hd or a 4k it always creates an 320x200 quality video!

does not download anything unless you install another software. crap.

This add-on is not what it used to be. You need to install local Software in order to use it and you also need to buy premium in order to use it properly. But Premium is way too expensive. I will Just use JDownloader instead. It is free and works better. This Add-on is bull**** DO NOT INSTALL.
