Youtube is a great source of all manner of videos of every genre. Unfortunately, being as Youtube is a streaming video service, you need to not only be online, but you need to have a high-speed Internet connection to be able to access it and view them. This makes it impossible to share great videos with people on slow connections or who do not have access to the Internet. Using Firefox and a few simple extensions, it is entirely possible to download them to your computer for future playback.
