How to check your rapidshare link valid or not before you download. First you must have the latest version of Mozilla Firefox Installed. ( Download Firefox )

Next download the extension for it called “Grease Monkey”. ( Download ) . Grease Monkey allows you to customize the way a webpage displays using small bits of JavaScript.

Finally visit userscripts.org and install this script into grease monkey. It will now scan every page you visit for rapidshare links and it checks them automatically before you even visit them. I can check a page with hundreds of links in just a few seconds. The image at the top shows what it will look like when it scans the links.
