Test:

            $(function() {
                $('#container-9 ul').tabs({ disabled: [3], fxFade: true, fxFade: true, fxSpeed: 'fast', cache: true });
                $('<p><a href="#">Remove 2nd tab (error: you cannot switch to tab 4)<\/a><\/p>').prependTo('#fragment-22').find('a').click(function() {
                    $('#container-9 ul').tabsRemove(2);
                    return false;
                });
                $('<p><a href="#">Add new tab<\/a><\/p>').prependTo('#fragment-22').find('a').click(function() {
                    $('#container-9 ul').tabsAdd('test3.html','tab 4');
                    return false;
                });
                $('<p><a href="#">Remove 2nd tab<\/a><\/p>').prependTo('#fragment-22').find('a').click(function() {
                    $('#container-9 ul').tabsRemove(2);
                    return false;
                });
                $('<p><a href="#">Add 2 tabs<\/a><\/p>').prependTo('#fragment-22').find('a').click(function() {
                    $('#container-9 ul').tabsAdd('test1.html','tab 2');
                    $('#container-9 ul').tabsAdd('test2.html','tab 3');
                    return false;
