very powerful ,but can not detect the type of stream video

After trying various downloaders this is the one that satisfied me. You need to install the software on your PC to use it. If you have difficulty, just send an email to the support site, they always answered in a short time to me. A must for all browsers.

very good

Excelente gestor de descargas

I think the first reviewer didn't give this a fair trial - it's wonderful!

Yes, you need to download the extra piece of software to your computer (but so do several other video downloaders). This one sits on your desktop, and works beautifully with Firefox 57 and Windows 10 (latest version).

As I have downloaded 6 other video downloaders in the past 2 days (and unistalled them because they simply didn't work) I am so happy to have found one that does the job. I highly recommend this one.

good

The Development of Ant Download Manager had the good foresight to listen to Mozilla and update their add-on, before the final release of Firefox 57. As a result, it is completely compatible.

A very useful download manager too.
