A friend of mine is struggling with a medical XUL app built by a large biotech company. They're stuck on Firefox 3.6 due to XUL incompatibilities with newer versions of XUL. Where can my friend go to get info and or advice about how this corporation might update their XUL app to a newer XUL runtime?
