// Ensure that the facebook mobile site never shows its app banner, which
// suggests installing a native Android/iOS application based on naïve
// parsing of the UA string.

// The banner does not currently have any class or id that would make sure we
// can identify it easily. But we know that it does always appear just before
// the login form, so we find it that way.
