A possible cause of this message is that Firefox is set to run as Administrator.

Check that Firefox isn't set to run as Administrator.

Right-click the Firefox desktop shortcut and choose "Properties".

Make sure that all items are deselected in the "Compatibility" tab of the Properties window.

• Privilege Level: "Run this program as Administrator" should not be selected
• "Run this program in compatibility mode for:" should not be selected

The issue was that Firefox wanted to install an update so it needed elevated authority to do so. Thereafter it has not asked.
