Is there an administrator for your computer? That is the password you need.

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

Thanks. I don't know. The software was uninstalled and the icons on the desktop was deleted. Is there anyway to reinstall the Mozilla Firefox? Thank you.
