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 * This function provides a simple assertion function for JavaScript.

18 * condition is false, then the message will be printed to the console
19 * and an alert will appear showing a stack trace, so that the (alpha
20 * or nightly) user can file a bug containing it. For future enhancements,
21 * see bugs 330077 and 330078.

23 * To suppress the dialogs, you can run with the environment variable
24 * XUL_ASSERT_PROMPT set to 0 (if unset, this defaults to 1).

27 * true when we call this function--should be
28 * something that can be evaluated as a boolean.
