why does firefox create a new cookie instead of over writting the existing one?

more options

I am using javascript to set a cookie like this: `document.cookie = "name=" + window.location.href;`

I'm not sure if it matters but the javascript is in a child theme in Wordpress.

In Chrome and Safari it will create one cookie and update that one cookie when I changes pages on the site. In Firefox it creates a new cookie with the same name and new value.

Can I even fix this?

You may notice each cookie has a different path. Firefox defaults the path to the current page's path if you do not specify a consistent path like

document.cookie = "name=value;path=/"

in your cookie assignment.
