The add-on coerces users to download a companion app. The video files for which it suggests it's companion app is required are easily downloadable by the direct http address of the video, proving further that the app uses disinformation to achieve its goal of installation of its "companion app".

The companion app analysis is shown here which contains a range of malware activities;

Latest update has made it necessary to also update Companion App. It says you just need this for ADP downloads, but even if you select a HLS download it also insists on the App.
Then your download ADP gets "Watermarked" with a QR code, and you have to pay to remove.
Claims Watermark is only on ADP, but if you download HLS, only get Audio...

Used to be great. Now it's not. Pick one of the many other options.

watermark ruins videos

Used to work great, then got enshitified. Requires app to download and forces payment to remove watermark.

no funciona, no hace mas que pedir la aplicacion auxiliar (que es una aplicacion auxiliar, yo no pedi una aplicacion auxiliar) que esta instalada y aun despues de reiniciar, cosa que no solicita, sigue pidiendo. a lo mejor despues de batallar un rato consigo algo, pero es frustate tener que batallar

С Firefox НЕ РАБОТАЕТ ВКонтакте. Показывает обрывки видео, целиком не качает.

Doesn't work

still broken, many videos only download partially

forced auto update broke the previously working app telling me to update the companion... very sketchy and sad to see

Now-required companion app gets flagged as malware by my anti-virus software. App does not function without this companion app so I guess I have to look elsewhere for a downloader. Too bad, this was a great app.

How unfortunate. This was once a very useful tool, but now suffers from an unreliable companion app to function properly. Sadly, as of the latest update (1/4/2024), the companion app installer now triggers my antivirus software as a Trojan.

pay $20 or watermark videos with huge non-transparent QR code ruining the entire video. Is this the most useless addon to firefox now? It's certainly trying hard to be.

At some point, this extension stopped working on virtually all sites. The only information is that you can download separate conversion software which works nightmarishly. The extension is not worth a fart, I have no idea why it still has any badges.

Not working on Onlyfans Also New Version Is Slow Like Snail Slow. looking for a new Program that works better than this one.

Enshittified. Companion app required to download files now adds a giant QR code watermark in the corner.

This extension does not work. FB reels downloaded but can not be played.
