Fügt seit neuestem unangekündigt einen QR-Code in Videos ein, den man ausschließlich über den Erwerb einer teuren Lizenz zum Konvertieren verhindern kann. Das war's, tschüß!

Without installing an external tool called a companion app, this add-on by itself cannot do anything.

Causes a lot of lag on Youtube streams and embeds. Fails to pick up audios on some videos. Not really needed if you know how to download without it.

After the last couple of Firefox updates (using Linux Mint) the apps started to download, only to find that there can be only a couple of minutes actually downloaded.
Tried to use this app on LibreWolf (tired of Firefox changing my settings for IPv6) but claims the video extension isn’t installed.
Used to be perfect, doesn't work on Librewolf so for me it's now useless.
Update,
Now even worse with this quick download nonsense telling you that it will download where it wants too.
Removed, may also change browsers as non of the video add-ons work as claimed mainly due to Mozilla.org.

Fuck your extension. It sucks. In 50% of cases it doesn't download the whole video. And what is this ADP bullshit and convert for YouTube videos. I can literly use a YouTube downloader website and it downloas an .mp4 video in in its entirety with sound and video with no watermark. So yeah, fuck You and your extension.

Latest version is not able to download from several sites which the previous had no problem with, the new interface is worse and, most importantly, if you are downloading from a page where the media is changing periodically the new version will make a mess with smart naming changing the name of all the media link it found in that page and you will not be able to understand which is the correct media you want to download.

Inserta un QR en los videos descargados. Si se lee la descripción de la extensión, no dice en ningún lugar que vaya a hacerlo o que los videos tendrán ese QR sobreimpreso.

Doesn't work. Will not allow me to download helper to mac. Worked on one in 10 videos tried on PC.

You to pay to get rid of watermarks on YT videos, and it's ridiculously expensive. Edit: use "dirpy", worked for me but it's a site not a addon.

Addon never works, it does not download any videos (on any website that has video embedded). All it provides are tiny "video" files, none of which are the actual video! I have used many addons over the years, this is definitely a faulty one.

Der letzte Rotz, die Daten werden irgendwohin gespeichert, in Einstellungen nix zu finden, man sucht und sucht. Scheiß Programm!

Warum gibts da keinen Hinweis und Einstellung? Das ist ein MUST Have, kein COULD Have! Unbrauchbar und Zeitverschwendung

Very misleading addon that doesn't tell anything (not on the addon webpage or in the youtube video) about requiring installing a standalone program of unknown origin.

requires installing a standalone app of unknown origin. should work directly from browser

so bad.

Everytime i download a video 30-40% into the video the audio fallls out of sync

Péssimo. Simplesmente não funciona no Linux. Não tem um arquivo .rpm só tem arquivo .tar e o REDME do arquivo não explica nada.

no audio in any of the videos downloaded, garbage extension

慢的要死

Asks for payment to remove huge watermark in generated video. There are free alternatives, don't bother with this.
