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: Testing regexps with the global flag set.
  * NOT every substring fitting the given pattern will be matched.
  * The parent string is CONSUMED as successive matches are found.
  *
  * From the ECMA-262 Final spec:
  *
  * 15.10.6.2 RegExp.prototype.exec(string)
  * Performs a regular expression match of string against the regular
  * expression and returns an Array object containing the results of
  * the match, or null if the string did not match.
  *
  * The string ToString(string) is searched for an occurrence of the
  * regular expression pattern as follows:
  *
  * 1.  Let S be the value of ToString(string).
  * 2.  Let length be the length of S.
  * 3.  Let lastIndex be the value of the lastIndex property.
  * 4.  Let i be the value of ToInteger(lastIndex).
  * 5.  If the global property is false, let i = 0.
  * 6.  If i < 0 or i > length then set lastIndex to 0 and return null.
  * 7.  Call [[Match]], giving it the arguments S and i.
  *     If [[Match]] returned failure, go to step 8;
  *     otherwise let r be its State result and go to step 10.
  * 8.  Let i = i+1.
  * 9.  Go to step 6.
  * 10. Let e be r's endIndex value.
  * 11. If the global property is true, set lastIndex to e.
  *
  *          etc.
  *
  *
  * So when the global flag is set, |lastIndex| is incremented every time
  * there is a match; not from i to i+1, but from i to "endIndex" e:
  *
  * e = (index of last input character matched so far by the pattern) + 1
  *
  * Thus in the example below, the first endIndex e occurs after the
  * first match 'a b'. The next match will begin AFTER this, and so
  * will NOT be 'b c', but rather 'c d'. Similarly, 'd e' won't be matched.
