Automatically check whether rapidshare, megaupload and filefactory links are working or dead without

1. Install Firefox from: http://www.getfirefox.com
2. Install Greasemonkey extension from: https://addons.mozilla.org/en-US/firefox/addon/748
3. Install Rapidshare Links Checker script from: http://hosts.890m.com/userscripts/r....RC.20090428/rapidshare_links_checker.user.js

Links that are alive will show up as a green tick. Dead links will show up as red crosses. This works for rapidshare, megaupload and filefactory links.
