javascript - Javascript: in ff in history object custom function disappears

Question

I have strange situation in ff. I added custom function to history object and after some time it disappears. Is that some kind of ff protection of default objects or what? Maybe when new state added to history it kills my function?

All other browsers is ok.

PS I can use some custom object instead of history, but I want to know whats wrong with history object

履歴の特定の実装を知らなくても、FireFoxそれを変更してデフォルトの状態に戻すと、ブラウザは特定の条件下でそれをリセットすることが多いと言えます。カスタム実装に履歴を使用しないことをお勧めします。
