Easiest way to save Youtubes

Hopefully you have been checking out youtube content that is available in easy to digest portions that is the same size as the average teenagers attention span. Saving them can be a pain... but hurt no more!
The first thing you need to do is to download a free browser Mozilla Firefox. Personally i have ditched Internet Explorer altogether. IE is not the best browser, it just comes bundled with Windows and Bill Gates has already got into big trouble for his anticompetitive strategies of not making IE separate from Windows. I was having problems with IE accepting my cookies (no cookie monster) and so I downloaded Mozilla Firefox, a free, open source browser. Firefox looks not unlike IE, so it is no real change, although you may notice that Firefox crashes less often. (I haven't had one crash so far) It is perfectly ok to run both browsers if you wish, they don't conflict with each other in any way.

Then download a Firefox add on, Downloadhelper.

It puts a button on your tool bar that becomes animated when video content is on the screen.

Then you visit whatever site with embedded video content. You click the drop down menu next to the pretty button and choose which video you wish and voila! Firefox's download manager starts downloading the file! Nicely named whatever youtube called it!

Make sure you place it on your school server for all staff to access.
