Download video from every site

In this tutorial I will explain two ways to download videos from the internet, ie. from sites which do not allow you to download, just to watch. For downloading videos from such sites (YouTube, video.google ...) using your Mozilla Firefox and the Video DownloadHelper.

1. Install Mozilla Firefox, you are not running.
2. Go to https://addons.mozilla.org/en-US/firefox/addon/3006 and click on Add to Firefox,
3. wait to be installed and restart.
4. When FireFox start go to a page with a video clip,
5. press the DownloadHelper-which is located between the Address and the Home icon,
6. drag the pointer to the first file from the list and click Download.
7. You have successfully downloaded the video from the Internet.
