The developer of this extremely powerful plug-ins has done a great job of ensuring you can download any vids. A lot of user documentation but I do fumble still with the options. All-in-all, great work!

Awesome add on!!! Be sure to add the HLS plugin for this to be an extremely versatile tool.

good tool

これまで使っていたダウンロードソフトの中で一番で素晴らしいソフトです

Realmente es un complemento muy completo, se agradece a todos los desarrolladores que han hecho posible el uso de esta muy útil herramienta,si pudiera le daba 7 estrellas

I've found Video Download Helper very helpful in my studies. I see they need money and I'd like to send some but it would have to be a cheque in $Can and I need their mailing address.

If you're looking for an app that's simple & easy to use, this software works great for downloading videos for personal use. Quality of downloaded videos is good.

THIS IS THE BEST DOWNLOADER I HAVE HAD, EASY TO USE AND EFFICIENT.

BEST PROGRAM OF ITS TYPE THAT IVE USED

this add-on is awesome.

当我发现这个插件的时候，空气仿佛充满了氧气，让人兴奋。

Used to get the job done satisfying, but not anymore. The video lags when I click around now and the quality is subpar. Much worse than before, and I assume it's intentional. What a shame
