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

No UAC
Note: 64-bit versions of Windows do not use the Mozilla Maintenance Service.

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 service doesn't run so it doesn't use any computer resources. And once the update process begins, the service 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.
