Conditionally enable double key logic according to:
private browsing mode or privacy.thirdparty.isolate preference and

michael@0	9	* Revised: 14 July 2002
michael@0	10	*
michael@0	11	* SUMMARY: JS should NOT error on |for(i in undefined)|, |for(i in null)|
michael@0	12	*
michael@0	13	* ECMA-262 3rd Edition Final spec says such statements SHOULD error. See:
michael@0	14	*
michael@0	15	* Section 12.6.4 The for-in Statement
michael@0	16	* Section 9.9 ToObject
michael@0	17	*
michael@0	18	*
michael@0	19	* But SpiderMonkey has decided NOT to follow this; it's a bug in the spec.
michael@0	20	* See http://bugzilla.mozilla.org/show_bug.cgi?id=131348
michael@0	21	*
michael@0	22	* Update: Rhino has also decided not to follow the spec on this
michael@0	23	* See http://bugzilla.mozilla.org/show_bug.cgi?id=136893
