On the website that has a redirection from domain.com to www.domain.com there is a cookie __utmz
that is set with this plugin:
https://github.com/clancychilds/ReturnOfTheUTMZ/blob/master/compiled/latest/utmz.min.js
Apparently, this cookie is set on .domain.com not on www.domain.com. Here are cookie details:
Name: __utmz
Content: 0.1234567890.1.1.utmcsr=blablabla.co.uk|utmccn=(referral)|utmcmd=referral|utmctr=/blablabla
Domain: .domain.com
Path: /
Send for: Any kind of connection
Accessible to script: Yes

Expires: Sunday, July 23, 2017 at 4:34:02 PM
Now im trying to remove this cookie from all browsers visiting the website, but nothing of the following worked so far for my browser:
document.cookie = '__utmz=;domain=.style.com.;expires=Thu, 01 Jan 1970 00:00:00 UTC';
document.cookie = '__utmz=; expires=Thu, 01 Jan 1970 00:00:01 GMT; path=/';
What would be the best way to remove this cookie using JS (no access to jquery or any other library)?
