Firefox with opened firebug console throws too much recursion using sammy.js and knockout.js

Question

After last update of firefox (I asssume) I have problem with firebug console. In my app when I combine app.refresh() with setting observable on get "too much recursion" is thrown and firefox is not responding. When I close firebug console everything works well.

In my viewmodel I have:

self.firstStep = ko.observable();

var app = Sammy(function () {
    this.before({ only: { verb: 'get', path: URL.FirstStep } }, function (context) {
        console.log("before");
    });

    this.get(URL.FirstStep, function () {
        self.firstStep(new firstWindow());
        console.log("get");
    });
});

self.LoadData = function () {
    $.ajax({
        //...
        success: function (data) {
            //here is commented out because of debuging the problem
        },
        complete: function () {
            app.refresh();
        }
    });
};

app.run();
self.LoadData();

Get in console is logged once, before is logged twice. When I comment out self.firstStep(new firstWindow()) get is fired twice too. In chrome everything works fine. Help really appreciated.
EDIT: @Mörre
When I modify code like:

this.get(URL.FirstStep, function() {
  self.firstStep = ko.observable();
  self.firtStep(new firstWindow());
  console.log("get");
});

it is working.

如果您不需要使用“脚本”面板调试JavaScript，请禁用“脚本”面板为我解决此问题。
