Use a dedicated download extension to download videos.

• Video DownloadHelper: https://addons.mozilla.org/firefox/addon/video-downloadhelper/
• Flash Video Downloader - Youtube Downloader: https://addons.mozilla.org/firefox/addon/flash-video-downloader-youtube/

I have not asked alternative download software. I want tutorial like instructions thank you cor-el

The first source of support for add-ons is from the developer of the add-on.

There is no clear instructions , I have gone through all the pages of faq and their developer notes. They are not clear. Download helper supports download videos but not resume support, which downallthem says to contain.

Sorry, I don't use that extension myself. You'll need to wait for a support helper who actually uses that extension for help.

When surfing thro net exhaustively, i found the answer to my question. After you download the add on , you must select the preferences options, menu and then in it, the general menu. You please enable picture and video tab enabled. Select the video, allow play, use firefox tools, downthem all, click on it and go the picture and video tab, get the sniffed video there ,tick it and download.ok. This is the easiesy way of avoiding so many unwanted handles in the downloader. rename the video and play with available players. if they do not play, play the video with vlc media player. This downloader is a marvellous add on from firefox, which can download 'downloadable videos,' not all videos.
