WAS great. NOT FREE!!! Charges to convert to the most used format.
"Flash and Video Download" 1.0.9.83 by Download Flash and Video Team, is working great!
BUHbye.NOT buy buy.

This extension does nothing. It requires an EXTERNAL APPLICATION to do anything. This is useless.

Funciona excelente! Para mantener el espíritu original de Internet!

Not actually free.

I've been using this extensions for years and it has never let me down. My library is what it is because of this extension.

Grandiosa app, en ocasiones se cancelan los videos porno pero los puedo volver a descargar en otro momento

Best download program i've ever used

This is the best download program I have ever installed.

Nonsense, absolutely.
if you have only one video on the page, for example 5 MB of size, the extension shows you at least 5 non-working links with size of 1024 KB (all links are the same), couple of links with correct size and name, but they don't work, and finally one working link, but with auto-generated numeric name. And it's 50% chance that download will not be finished.
The same time i tried 2 other extensions, and the work as should exactly on same pages.

Wondershare's Video Downloader does a far better job in much less time and with much less hassle.
