This engine has proven to be an awesome alternative to google when I'm searching for files, since google searches for text, and sometimes ignores the "download" keyword.
I used this engine to an extent that I started to wish that I had this search engine next to google and wikipedia in my firefox search bar. I searched for a firefox addon, and even though I stumbled upon some rapidshare search addons, none of them were nearly as good as filecrop.
So, I decided to make my own filecrop search addon..., and I did! Now you can download it for use on your firefox!
DOWNLOAD
UPDATE: Instead of using this, you can simply use "Add to Search Bar" add-on for firefox. It's easier to use, and it supports all search engines.
