Changes
Further details on XMLHttpRequest.
* catch (ex if ...)
* |Services.intl.createDateTimeFormat(...)| in Thunderbird 57 and 58 changed to |new Services.intl.DateTimeFormat(...)|
* Components.classes['@mozilla.org/xmlextras/xmlhttprequest;1'] changed to new XMLHttpRequest();. Potentially you need to add Components.utils.importGlobalProperties(["XMLHttpRequest"]), which might not be necessary from version 61.
== Changes in thunderbird59 ==
* All attributes of nsIURI.spec are read-only, use for example url.mutate().setQuery(aQuery).finalize(); More examples in {{bug|1440693}}.
* Components.utils.import() has changed to ChromeUtils.import(). The old form still works.
== Outlook and Suggestion ==
