Firefox now installs an optional program called the Mozilla Maintenance Service. This program allows Firefox to install updates without requiring you to click yes in the Windows User Account Control (UAC) dialog.

No UAC

How does the Mozilla Maintenance Service work?

Once Firefox has downloaded an update, the Mozilla Maintenance Service gets permission from Windows to allow the update to be applied without requiring you to click yes in the Windows User Account Control (UAC) dialog. Until that time, the program doesn't run so it doesn't consume any resources. And once the update process begins, the program quits.
Note: Even though Windows XP doesn't include the UAC dialog, the Mozilla Maintenance Service is installed so that we can further streamline the update process in the future.

Note: You can also uninstall the Mozilla Maintenance Service through the Windows control panel.
