I would like to share some info about lite and easy to use open source Firefox browser add-on that enable you to download YouTube Videos on single click and save it to your local computer. Install this add-on “1-Click YouTube Video Download” and you can start download videos from one of the largest portal of different videos by using Firefox browser.
Just Install “1-Click YouTube Video Download” on Firefox browser and then you will see small links in YouTube to download videos and music in 3GP, MP4 HD (High Definition), MP4 High-Quality and FLV.Click on the link to download the video in that format. After downloading the video, you can then watch it offline or transfer it to Apple’s iPod and to most modern mobile phones. To watch videos on your computer you’ll need a video player capable for playing MP4,3GP or FLV files.
