I've a Macbook Air and used Safari in the past, but trying out Firefox as it has the ability to put Facebook in some sort of magic box that limits ability to track everything. All going well, other than Safari keeps starting up when closed. I've made sure Firefox is the default browser, Safari always opens up the last page accessed, I've changed this to check and definatly the last page, so not page dependent.
Any clues?
