After dismissing the cookie notice once, it appears on every page and clicking it has no effect. Affects both firefox and chrome, logged in or not.
The cookie EU_COOKIE=1 gets set on the first click. Deleting it allows me to dismiss the box again, but then it's back on every page view.
edit:
I did a full ctrl+shift+r refresh to make sure there wasn't stale js cached or anything like that.
