The unprompted elevation mode should be checked only if the user can elevate
Steps to reproduce: 1. Change the UAC setting to unprompted elevation mode. 2. Log on as a standard user. 3. Launch Firefox. 4. Make sure Firefox is configured to use the maintenance service. 5. Open the About dialog. Actual result: UAC prompt will displayed on restart. If the user does not know administrator's credential or if UAC is configured is to auto-deny the elevation request from the standard user, the user can not update. Expected result: Updater should use the maintenance service.

Brian, could you diagnose what could be going on here?

FYI the logic is basically taken from nsXULAppInfo::GetUserCanElevate().
I removed the check for the "EnableLUA" registry key because it is not only useless but also harmful. - If UAC is enabled, that's fine. - If UAC is not enabled, it is impossible for the user token to be TokenUserLimited. - As the old comment explained, the "EnableLUA" registry key does not reflect the real-time system state. Unlike "EnableLUA", "ConsentPromptBehaviorAdmin" and "PromptOnSecureDesktop" will be reflected immediately (I tested).
