708119 - Extending JS Object results in error

Status: UNCONFIRMED

(Firefox :: General, defect)

Description

[Federico]

Attachment: quite simple library

User Agent: Mozilla/5.0 (Windows NT 5.1; rv:8.0) Gecko/20100101 Firefox/8.0
Build ID: 20111104165243

Steps to reproduce:

I extended Object via JavaScript (this is allowed in ECMAScript and is supported by ALL browsers):

Object.prototype.xxx = function ()
{
	return 1;
};


Actual results:

If I insert that code in any script which is perfectly working, I get an error.


Expected results:

Because www() is not invoked, scripts should at least work as if it wasn't there.
