I know, it might be a noob question...
I want to add a custom menu entry to Mozilla or IE, that when clicked
executes an external java application.
But i am already unable to do the first step.
I'd like to access browser.xul which is in browser.jar, but when
trying to
open browser.xul with netbeans, an unexpected FileNotFoundException
occurs.
java.io.IOException
