Answer 1

    $(window).bind('unload', function () {
        if (/Firefox[\/\s](\d+)/.test(navigator.userAgent) && new Number(RegExp.$1) >= 4) {
            console.log('firefox delete');
            var data = { async: false };
            endSession(data);
            return null;
        }
        else {
            console.log('NON-firefox delete');
            var data = { async: true };
            endSession(data);
            return null;
        }
    });

    function endSession(data) {
        var id = 0

        if (window) { // closeed
            id=1
        }

        $.ajax({
            url: '/api/commonAPI/'+id+'?Action=ForceEndSession',
            type: "get",
            data: {},
            async: data.async,
            success: function () {
                console.log('Forced End Session');
            }
        });
    }

Use if (window) to determines if closed or just reload. working for me.
