Wow! It does everything they say it does.
It's a little clunky because it is external, but I like it. :0)

addendum: oops! It ran for perfectly for 27 days and today the download manager has stopped... no explanation, it just quit working?

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.

Not very good. This is not a stand-alone.

Its the most wasted time EVER on downloading software/addons.
45 minutes after installing and STILL not done close to what it says, managing downloads...
Installed "Youtube downloader" and 30 seconds after installing first download was managed and saved.........

good

Good

I it love download just about anything from you tube to movie sites it is awesome

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.
