change window.navigator JavaScript

Question

I'm trying to change window.navigator. But for some reason can't change it:

--
[10:40:28.802] window.navigator['buildID'];
[10:40:28.811] "20121129162756"
--
[10:40:47.225] window.navigator['appCodeName'] = "I want to change it";
[10:40:47.234] "I want to change it"
--
[10:40:55.633] window.navigator['appCodeName'];
[10:40:55.643] "Mozilla"
--
[10:41:02.405] window.navigator['myProperty'] = 'someproperty';
[10:41:02.414] "someproperty"
--
[10:41:07.651] window.navigator['myProperty'];
[10:41:07.660] "someproperty"

Hope my question is clear: 'How to change window.navigator?'

You can't. Its pre-existing properties are read-only. Why you would want to modify it is beyond me...

No, but why would you want to? – Niet the Dark Absol Jan 02 '13 at 15:50
I use JavaScript with python, and need to have my own version of browser. – Vor Jan 02 '13 at 15:51
That makes no sense... But anyway, it's read-only and that's that. – Niet the Dark Absol Jan 02 '13 at 15:51
