    Bug 24056: Use en-US strings in HTML forms
    
    When privacy.spoof_english = 2, we should hide the user's
    locale in content. So we use en-US default strings for HTML
    form elements, such as a Submit button.
    
    We also force GetLocalizedEllipsis() to always return the
    ellipsis used by en-US.
