It's a great app to download videos. There's only one flaw: when the extension is enabled and you play a live stream on Youtube, the CPU usage goes to the roof. I have to disable it and reenable it when finished.
It also works on some sites but not in others. In many of them the video is jagged and you have to pay to fix it

Yo bajo mis videos de mi Canal YouTube para repararlos

Tried numerous other helpers and, for me, this is the easiest and best. Quickly grabs and downloads media fast and easy.

ottima app per donwload di facile installazione ed uso la consiglio vivamente ad oggi ha un ottima funzionalita e permette di scaricare file dai vari siti ove altre estensioni hanno difficolta ad accedere.

Excelente!!!! lo mejor que he utilizado

好多插件中，最好用的一个。
下载了三个百个文件了，过来评价一下。

This add on has helped me through a lot of websites. Kudos to the developers for such a great experience

working fine on Windows 7

Extrêmement polyvalent, j'utilise depuis longtemps, très très rarement pris en défaut d'échec du téléchargement.
Merci.

The download helper use to be very good, but now it no longer provides the same service. Previously it provided multiple options for downloading a video but now only provides one from ADT. ADT is extremely slow in downloading and often the download fails to complete. On occasion it downloads the video but not the audio. I use it both on Win 10 and Linux Open Suse.

The problems I am guessing occurred via some updates, not sure if it was Firefox or Download Helper. I did not make any changes so it had to be a change in the software. I wish there were a better plugin since this one no longer provides proper service.

Devo dire Negli nni è migliorato parecchio

Удобнее расширения не встречала ещё. Просто, быстро, без заморочек. Спасибо!

Used to be great and helpful; now it doesn't work anymore without some shady "companion app" (i won't install your software outside Mozilla, sorry). Uninstalled after years of use. Pity.

Best All round Video and Audio downloader out there

I understand that they need funding for this add-on but £18.50 seems excessive considering there are several free alternatives.

Soundless videos, watermarked videos, or not detected at all. Too many struggles for such popular extension.

Sehr hilfreiches Add-on, das viele Einstellungsmöglichkeiten bietet

用了很多年了，有些其他插件下不了的视频也能下载，确实很好用。

doesn't save video, only audio, even with the companion app installed (also it says it would watermark converted videos)
