The download function works well, but the application has a very negative impact on computer performance, even if no video is to be downloaded at all. To be able to watch the video smoothly, the application must be deactivated.

Te obliga a descargar una aplicación externa (ya esto es raro), es muuuuuuuy lento en las descargas, no indica la velocidad de descarga. Lo único interesante es el desplegable con las opciones de las descargas y calidades disponibles y que sale una miniatura del video.

Poor interface. The QR watermark is massive.

Estava perfeito até agora quando já a dias estou baixando videos, e ao abri-los, o audio esta normal, mas a imagem esta super rapida em desacordo com audio e um video de 1h é transmitido a imagem em menos de 1 minuto. Ao finalizar o video, o audio continua em tempo normal, porem a imagem do video já foi processada em velocidade super rapida. O que devo fazer?

É bom, é útil, mas tem deixado a desejar ultimamente.

HLS Streaming downloading always failed in Twitter DM Videos.

freezes browser if enabled while on twitch, but otherwise works well.

Works often, but I'm sick of getting
"ENOSPC: no space left on device"
even though I have space to save the video a hundred times :-(

It works, but it costs 18€ to get rid of an ugly watermark in the top right corner.
No word about that in the add-on description though. :(

I understand that developers want money for their work, but then say it upfront.
There's a lack of transparacy going on here.

You also need to download a companion app, by the way (kind of a video codec?) or it won't work.

Was great on Ubuntu, even worked on sites with tricky JavaScript-enabled videos like saddleback.com, but now (probably due to the new snap-based Firefox on Ubuntu) just says I need to install the companion app (which is already installed). Unfortunately, going to the support link here or on the plugin's home page just takes you to a Google Groups page that displays "Banned content warning". Not sure if this is Big Tech trying to squash a tool to download from YouTube or what, but it means the plug isn't useful on Ubuntu any more. :(
