FB.getLoginStatus() return "unknown" in Firefox when user is logged

Question

In my site I test if a user is logged on Facebook in order to suggest him/her to like my Facebook site page.

Then, I use the conventional Facebook Js SDK function to understand if the user is logged or not:

FB.getLoginStatus(function(response) {
    if (response.status === 'connected') {
        var accessToken = response.authResponse.accessToken;
        fbuid = response.authResponse.userID;
        status = 'connected';
    } else if (response.status === 'not_authorized') {
        fbuid = null;
        status = 'not_authorized';
    } else { // the user isn't logged in to Facebook.
        status = 'generic';
        fbuid = 1;
    }

    that.evaluateFbStatus(status, fbuid);
}

It works perfectly with every browsers except Firefox.

In Firefox it returns always unknown even if the user is logged on Facebook and the status is not_authorized or connected.

Any help is accepted.

The problem is due to third party cookies.

To use Facebook SDK functions in Firefox, is necessary to open setting and able third party cookies Preferences > Privacy > Accept-third-party cookies

Have a look on this page for more details.
