Github user mephi42 commented on the issue: https://github.com/apache/zeppelin/pull/2816 @zjffdu I'm currently trying to stabilize them on my local machine. There are still a couple things that need debugging - the worst one being that sometimes click() on e.g. Login button produces no effect. @felixcheung, to me this is a useful safeguard when running locally and new Firefox is by accident in $PATH.
