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.

  * Date:    23 October 2003
  * SUMMARY: Unescaped, unbalanced parens in a regexp should cause SyntaxError.
  *
  * The same would also be true for unescaped, unbalanced brackets or braces
  * if we followed the ECMA-262 Ed. 3 spec on this. But it was decided for
  * backward compatibility reasons to follow Perl 5, which permits
  *
  * 1. an unescaped, unbalanced right bracket ]
  * 2. an unescaped, unbalanced left brace    {
  * 3. an unescaped, unbalanced right brace   }
  *
  * If any of these should occur, Perl treats each as a literal
  * character.  Therefore we permit all three of these cases, even
  * though not ECMA-compliant.  Note Perl errors on an unescaped,
  * unbalanced left bracket; so will we.
  *
  * See http://bugzilla.mozilla.org/show_bug.cgi?id=223273
