sspitzer%mozilla.org 5048134510 fix for bug #350299: After clicking "Restart Now", the software update wizard can obscure the "confirm close" prompt from browser windows with multiple tabs. 
additional, after clicking "Restart Now", we need to disable the "Restart Now" and "Later" buttons, so that the user can't click on them again (while they are dealing with the "confirm close" prompts.

finally, improve the prompt scenario (by first focusing the wizard) where the user has paused in the middle downloading a software update, minimized the software update wizard, and then quit the app.
