En mi opinión personal, es la única extensión que permite descargar y convertir vídeos desde prácticamente cualquier sitio web. He utilizado muchas extensiones pero ninguna está a la altura de Video DownloadHelper. En cualquier caso, la mejor herramienta para la descarga y conversión de Vídeos que podemos encontrar y todo ello a coste cero. Genial.

Used to be good...
Now has watermarks and takes ages to download using 100% cpu ram resources.

串流(直播)視頻直播完後，存於YT上的視頻檔案，過後一天、二天、三天下載下來的檔案大小會愈來愈小。
基本上使用簡單，我喜歡！

Ein absolutes MUST HAVE !!! 5 Sterne !!!

Using 100% of my ram

Absolutely great ADD ON for Firefox. I have no words. It does its work pretty great.

AFTER taking over four hours to download and convert one YT file, it placed a QR watermark on the video demanding to be paid. Even if I paid (over $20), I would be spared the watermark only on future downloads—the hours I wasted on this video are lost. If This had been revealed beforehand, I never would have installed the add-on.

Extremamente fácil de usar e muito funcional

used this app a lot its easy to use and does what you want it to do..

This extension actually WORKS! Using an iMac with MacOS 12.4 and Firefox.

sehr gute app

excelente complemento

nice! thx! :) I'have donated a litte bit. Great respect for your work! :) Best wishes from Germany.

Excelente para baixar vídeos que não conseguia baixar.

Kept a pre-Quantum version of Firefox along with a previous version of Video Download Helper on a flash drive. This older version gets 5 stars and is excellent.
Sadly, the current version is much less powerful and needs a paid "Companion add-on" to work for many sites. No thanks.
Having to fire up the older version to download around 40% of the videos I want.
