2. Download Rapidshare Links Checker User Script and install the User script using GreaseMonkey.

3. Restart Firefox

Now, whenever you go to a webpage that contains Rapidshare, Megaupload, Filefactory, etc links, this User Script will come into play. If it finds dead links, it’ll have an X icon at the end of the link and a checkmark icon for a valid working link.
