Video DownloadHelper Companion App 1.3.0 doesn't work with Firefox 72.02 (Mac OS X Sierra 10.12.6)

一部使えないサイトはありますが、大変満足しています。便利なソフトだと思います。

эта программа решила все мои проблемы

このアドオンを利用させてもらい動画を400個ダウンロードさせてもらった。簡単な操作でだれでも手軽に使用できる。動画ファンのかた全てにお勧めできるアドオンだ。

Used to be helpful and free. Don't believe the star ratings without text, they are probably fake and intended to offset all the recent negatives. As mentioned repeatedly, it now requires a companion app and your hard-earned cash. Not gonna happen here, already removed from FF.

This ext. is crap. It leaves a big water mark that uses almost 1/4 of the viewing screen. And is requires a PAID license to work. Besides it doesn't work on some sites, like bbc news. DISAPPOINTED.

Cette extension fonctionne parfaitement. Elle est très pratique.

Excelente Add-On, estável e cumpre o que promete.

素晴らしいサイトだから、勧めたいです。

The watermark is ridiculous

Been using this for many years, now. An excellent extension. Does exactly what it claims. Most other extensions of this type that I have tried, appear to get confused by some media formats. That hasn't happened with DownloadHelper as yet. Highly recommend.
