You don't need to encapsulate your code into a self-executing anonymous function any more. While early versions of the userscript add-ons used to simply insert the userscript at the bottom of the page, nowadays these are executed in a separate context that still allows access to the global scope on the page, but doesn't expose the variables you create with the var keyword.
