What browser do you use? For Google Chrome it's:
 * Open the page
 * Hit the sidebar
 * Hover the mouse over "More tools"
 * Click "Save page as"
 * It will be like downloading a file, and it'll ask you where you'd like to save it and what to save it as (and in default, it'll save as a .swf since it's a .swf for duh's sake)
