Initially, it is working fine, but later it is adding QR code which is much greater in size. We have alternate add ons for video downloader.
DO NOT INSTALL IT.

だいぶ前から使用しているが使える！
現状維持でいている限り使って行きたいし、おすすめ

Antes era una de las mejores, ahora hay que esperar dos horas para descargar otro vídeo si no pagas. A veces no funciona. (Mejor alternativa: ytdlp.online)

For some time ive been using this, its just bad. Just get separate windows program not browser extension ( media downloader from github works better than that) If i remember correctly for most files you need to download program anyway and you dont know if your video will have paywall at some point by having huge QR code in it

アップデートでDownload先がFirefoxと別にできなくなった。動画タイトルも個別に付かない。どうなってんの？？

Super Video Download Add-On! Sehr flexibel, erfasst fast alle Video Streams, nutze es regelmäßig.

Excelente para hacer respaldos de videos importantes.

Funktioniert super. Bis auf Facebook und Instagram kann das Tool so ziemlich alles runter laden, was ich möchte.

in the latest version (v.10.0.271.2) downloading from "www.ceskatelevize.cz" does not work, the addon reports "waiting video". But the older version (9.5.0.2) is functional

最高です

Don´t know what they changed but the app worked fine yesterday and doesn´t work at all.

goood

Puts a giant watermark on the downloaded videos, uninstalled.
