This is VERY simple. If you don't get it you should jump off a bridge I found this out along time ago when I used to install scripts like 24/7 into Firefox lol. I just found the script again. This works for Rapidshare, Megaupload, Hotfile, and a few other Download sites. 1) If you're a n00b and don't have Firefox already then download it HERE 2) Download this Firefox Add-on (Greasemonkey) HERE 3) Install this Link Checker Script to Greasemonkey HERE Now when you view a page with links the Script will automatically check them for you instead of you having to click them and see if they are dead. Results: (Don't pay attention to the black blocks through the links I had to put those in there for legal reasons.) Dead Links: (Lines go through the links and a red 'X' is at the end) http://i996.photobucket.com/albums/af86/xRelaps3x/Deadlinks.png Alive Links: (Links are green with a green check mark at the end) http://i996.photobucket.com/albums/af86/xRelaps3x/Alivelinks.png
