Good time to all.
The script stopped working from Yandex.ru

I understand that yandex changed the URL
https://mail.yandex.ru/neo2 2015г.
https://mail.yandex.ru/u2709/ 2017г.

And these changes (leading to a step increase) are likely to be of little importance.
this.getHtml(this.dataURL,"_handlers=folders"); в 2015г.
this.getHtml(this.dataURL,"_model.0=folders"); в 2017г.


Professionals, very much ask you to fix the script for Yandex.
