Description

Cookie-remover.js does not remove a specific cookie on www.mikrobitti.fi. The cookie is set for mikrobitti.fi, which probably is the reason behind this (I did read the documentation: https://github.com/gorhill/uBlock/wiki/Resources-Library#cookie-removerjs-) The problem is that I cannot make a rule to remove it even if I have a filter for both domains.

The name of the cookie is Bhb2CdOB3V.
