Tried it on a couple of websites but it didn't work for me. Running Win7(64) with Firefox 115.18.0esr (64-bit)

It does not recognize the main video that's playing only some tiny trailer from the side panel (not YouTube).

it doesn't see the video on youtube

Best video downloader

動画サイトを開いても何も反応しません。もうFirefoxで動画ダウンロードは諦めたほうが良さそうです…

It does NOT work, whether you press play or whatever. Mozilla should not allow apps that do not work to remain, it wastes our time.

very good

機能しない。騙されないように。
