Hello. I had been running Windows 7 Professional on my MBP 2010 via Bootcamp for almost a year. There had been no major issue. However, after I upgraded Firefox from v 8.x to 9.0.1, the system does not seem to be stable. At one time, I had to force reboot the computer due to a system hang while playing video on youtube. How can I download to v 8.x while keeping all the settings/bookmarks?
