Download Youtube Video Using IDM (plus Firefox)

Videos posted in Youtube are not designed to be downloaded, they are to be watched online. But certain visitors prefer to download them as video files so they still are able to watch those videos even if there is no connection to internet. There are sites that offer links to those videos but they are often so crowded with visitors, make access slow or even fail.

We just need two applications, i.e. Mozilla Firefox (browser) and IDM (Internet Download Manager). Mozilla Firefox is available in Mozilla, it is a freeware application and IDM is available in its site, it is a shareware though.

After Firefox browser is readily installed, we just need to install IDM. Usually it is automatically integrated to Firefox. When restarting Firefox afterward, there is a notification that Firefox has added IDM extension. That's all. There will be IDM button above playing video when opening Youtube using Firefox (pictured) or the same button can also appear in bottom left of Firefox window. Just click this button and download starts instantly. Recent version of IDM is also integrated to Opera and Google Chrome.
