 In ESR52, I confirmed in the code and by manual observation that this
 functionality is not exposed in content. The getCalendarInfo function can
 be used from chrome code like this:

 const mozIntl = Components.classes["@mozilla.org/mozintl;1"]
 let x = {};
 let calendarInfo = x.getCalendarInfo();

 The only place in ESR52 where this is done is in a test:

 But this is not possible from a content script. So I think we should
 postpone this ticket to ff59-esr.
