In order to download from YouTube, download, and install the latest version of Free Download Manager. After that, reboot the PC, enable the plugin within your browser, and open a page on YouTube. Right-click anywhere on that page and select either Download all with Free Download Manager or Download video with Free Download Manager. The first option will allow you to download all the content of that page, while the second one will allow you to download only the YouTube video. Once you select what you want to download, select a destination directory, and click OK.
