How can I restore all of my synced data from Firefox 4 (Win) to Firefox 5 (Mac)

more options

Because of a computer problem, I can no longer access the data on my previous installation of Firefox 4 on a windows computer. I've recently started using a new mac computer, and I can't seem to restore the data using Firefox sync. I'm certain that sync was enabled on the previous installation as I've had it syncing with my mobile phone. How can I fix this issue?
