This turned out to be an extraordinary addon! I love it! I've always wanted to be able to add search engines in a simple way without knowing programming and SSS gives me exactly that! :D I was finally able to add a context menu search for Urban Dictionary. :D :D

Edit: I was wrong. This addon is not just extraordinary, it's EPIC!!! Once you figure out how to add new search engines, you can use it even as a translator. Guess what this address does to the selected text. :D
