It works. You need to download an external app (free).

This addon sucks up memory during YouTube live steams. Until this is fixed I have to disable it and give it 1 star.

Describtion hides the fact that you need to install additional software. Then it tells you to get a licence ... just don't ...

Works fine for years. Except a few websites.

Excellent tool, detects videos on most sites that are not obscuring the src. Tested on FFox Developer ver.94+ 64bit

Ich tendierte zwischen 3 und 4 Punkten. Doch, da es im Wesentlichen schon das macht, was ich von ihm erwarte, entschied ich mich für 4.
Obwohl sehr erfahren, hatte ich lange Zeit viele Schwierigkeiten, zu dem zu kommen, was ich mit "Wesentlich" meine. Kurzum, ich persönlich empfinde es wenig benutzerfreundlich und erst recht nicht intuitiv bedienbar. Aber es macht was es soll.

Excelent Piracy Tools :) Just Kidding. Actually it saves a lot of internet traffic during learning, while the same video is played again and again. Thank you mig (developer).

Installed add-on, downloaded video, video embedded with large QR code by DownloadHelper, deleted add-on.

The best!

Easy to use, will continue with it, had a few crashes/failures hence 4 stars.

very good

以前就聽說很好用,真的用了才知道「好用」有些謙虛了

Amazing add-on. Easy to use. I'm happy with this add-on. Thanks to mig.

This is an amazing tool for learning the pronunciation of new words.

Very easy to use and it works well. i dont know much about computers but i have no issues downloading MP4s i find online with this

激活功能強大，唯一选择。

works as intended for years on end since i started using it from 2007

I have used multiple down-loaders but I keep coming back to this one. It just works the best and most consistently.
