I have had this downloader among other apps for quite a while. I don't recall this app as having ever worked, at least this year. It opens File Explorer on my laptop, but the download always fails.

Scam

Useless in Android! Even in desktop mode it only causes lag!

Ca marche pas...

Not cool, i really don't recommend. Installed for a quick one click download for MP3 format from YT, but it send me in another page to make about 3-4 clicks which in the end open another app from Microsoft store that doesn't work most of the time. Also I discovered recently that THIS add-on is responsible for disappearing of images in search mode in Creative Fabrica website. Only for this thing alone i decided to remove this add-on

Прутня

Fccng useless. Looks like the same developer is flooding FF with the same plugin under different names.

As far as I can see it does nothing. Clicking the extension closes the menu, that's it. It's doing something, just not for you.
