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.

  * SUMMARY:  Regression test for Bugzilla bug 87231:
  * "Regular expression /(A)?(A.*)/ picks 'A' twice"
  *
  * See http://bugzilla.mozilla.org/show_bug.cgi?id=87231
  * Key case:
  *
  *            pattern = /^(A)?(A.*)$/;
  *            string = 'A';
  *            expectedmatch = Array('A', '', 'A');
  *
  *
  * We expect the 1st subexpression (A)? NOT to consume the single 'A'.
  * Recall that "?" means "match 0 or 1 times". Here, it should NOT do
  * greedy matching: it should match 0 times instead of 1. This allows
  * the 2nd subexpression to make the only match it can: the single 'A'.
  * Such "altruism" is the only way there can be a successful global match...
