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.

9 * SUMMARY: Test that interpreter can handle string literals exceeding 64K
10 * See http://bugzilla.mozilla.org/show_bug.cgi?id=179068
11 *
12 * Test that the interpreter can handle string literals exceeding 64K limit.
13 * For that the script passes to eval() "str ='LONG_STRING_LITERAL';" where
14 * LONG_STRING_LITERAL is a string with 200K chars.
15 *
16 * Igor Bukanov explains the technique used below:

40 * The reason for eval is to test string literals like in 'a string literal
41 * with 100 000 characters...', Rhino deals fine with strings generated at
42 * run time where lengths > 64K. Without eval it would be necessary to have
43 * a test file excedding 64K which is not that polite for CVS and then a
44 * special treatment for the compiled mode in Rhino should be added.

51 *
52 * The concat is a replacement for eval("str='"+long_str+"';"), but as
53 * long_str is huge, this leads to constructing first a new string via
54 * "str='"+long_str and then another one via ("str='"+long_str) + "';"
55 * which takes time under JDK 1.1 on a something like StrongArm 200MHz.
56 * Calling concat makes less copies, that is why it is used in the
57 * duplicate function and this is faster then doing recursion like in the
58 * test case to test that 64K different string literals can be handled.
