Conditionally enable double key logic according to:
private browsing mode or privacy.thirdparty.isolate preference and
implement in GetCookieStringCommon and FindCookie where it counts...
With some reservations of how to convince FindCookie users to test
condition and pass a nullptr when disabling double key logic.

16 * aOptions can have a variety of fields:
17 * headers, an array of headers
18 * postData, this can be:
19 * a string: send it as is
20 * an array of parameters: encode as form values
21 * null/undefined: no POST data.
22 * method, GET, POST or PUT (this is set automatically if postData exists).
23 * onLoad, a function handle to call when the load is complete, it takes two
24 * parameters: the responseText and the XHR object.
25 * onError, a function handle to call when an error occcurs, it takes three
26 * parameters: the error, the responseText and the XHR object.
27 * logger, an object that implements the debug and log methods (e.g. log.jsm).
28 *
29 * Headers or post data are given as an array of arrays, for each each inner
30 * array the first value is the key and the second is the value, e.g.
31 * [["key1", "value1"], ["key2", "value2"]].
