Useless. Doesn't work on any site.

There is now a forced giant watermark on videos now. No free option. Uninstalled

watermarks videos unless you pay them.

Keeps bothering you to install the "helper" application for basic functionality. Puts arbitrary limits on how many videos you can download within a certain period, this limit can be bypassed by uninstalling the extension, then reinstalling.

I have no problem with paying for open source software, but the fact that payment is required for some functionality should be made clear on the extension's page, and before the user spends potentially hours waiting on a video to download, only to find out this extension superimposed a massive QR code over the downloaded video.

Only works if you download the extension. Now it hits me with a popup in Russian every time I go to YouTube. Time to uninstall and find a new one.

After YouTube's hissy fit with adblock, and their continuous efforts to fight it, somehow that's affected this addon's ability to even detect videos. It no longer works, and obviously there has been no effort on the author's part to fix it.
Edit: Yeah, this addon is a scam, just like "Easy YouTube Video Downloader Express."

$30???? obs screenrecording is free you know?

It doesn't work on Y0uTub3 anymore...

giant fuck off water mark? uninstalled. fuck that noise.

Implies it's free. It's not, it's about 28 bucks.

Implies it's only an addon. It's not, it only works if you also download and install their extra software no doubt full of tracking to bypass Firefox data protection.

Implies that only certain 'converted' videos have a massive distruptive watermark. All videos in fact have a massive distruptive watermark that make the addons function pointless unless you pay. Very deceptive practices. Reported.

Doesn't work. Requires an external application which is only available for Windows 8+

Es lo peor que he instalado!! Se camufla como extensión gratuita. Luego, pide que se descargue he instale otra aplicación para poder descargar algún video. Luego, de instalar la segunda aplicación, descarga el video con un enorme código QR en la esquina inferior del video. Debería de poner una descripción completa, no una descripción dudosa e incompleta. Debería Mozilla de vetarlos para que realmente publiquen la verdad de lo que hace.

Раньше мог нормально перехватывать видео.
Сейчас с новым интерфейсом ничего не могу сделать.
Удаляю.

Used to be free. Now it costs $28.50, else you get a MASSIVE QR code in the corner.

I see no point in keeping this bloated resource hungry extension installed. It is worthless trash now.

it does not do the only thing it is meant to.

Giant QR code on video unless you pay $28.50 does not work for me.
