I'm finally able to download and save in MP4 webex streaming lessons.

とても優秀なアドオンだと思います。Very nice！！

The OG.

Great+++, interesting options, must have apps

Seriously, why is this even a recommended add-on? First of all it asks you to download a companion app. After it downloaded the file it started aggregating with an ETA of 5-8 hours. I stopped after 2 hours. Glad I did because the partially converted file had a QR code watermark which you can remove if you PAY. Rubbish add-on, stop recommending it, Mozilla.

Worked exactly as I wanted, even in an obscure website which seemed to do a pretty good job at making it nearly impossible to download videos via Inspect Developer Tools. Note that in order to download certain videos, a helper application will need to be installed. The add-on will instruct you how to install it. It's safe to install it. This add-on works with login-protected websites as well.

Excellent! Many thanks!

DO NOT INSTALL! It's a scam. It asks you to install a second "companion" app to make it work, and that "companion" app is an exe file that contains virus. Already reported to Mozilla.

Great experience with this helper. Thanks.

Works like a charm

Many thanks..

great app

超级不错

Honestly, one of the best downloaders I have ever used with firefox, period!!!

it used 10 gb ram while having it idle and most likely crashed my computer/softwares because of it. Once I disabled it the ram usage for firefox was back around to 500mb. Had only one tab open.

Der Downloadhelper ist das beste Tool für downloden und konvertieren von Videos, welches ich kenne.

Great add-on that does exactly as advertised. Simple to use and never had a single issue with it.
