Updated from version 7 to 8 & during setup message SETUP - Your computer must be restarted to complete a previous upgrade of Firefox. Do you want to reboot now? Options are "yes or no". Option "yes" reboots my computer & any attempt to open Firefox I get the same message. Rebooting several times has no effect. Option 'no' closes the file & nothing happens. Running XP Pro version 2002 SP 3. All normal programs have been updated to current date (Adobe, Java, etc).
