Check that you do not run Firefox 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
