I have not ever used XUL and it seems quite mysterious. What does it take to create a simple XUL application that simply loads a webpage on a Linux environment?. No need for window decorations, history, back or forward buttons. Just the simplest possible XUL app that loads a web page... Using xulrunner with GRE version 10.0.11.
Also, where is the best place to get tutorials to learn about writing XUL application?
