https://github.com/apache/zeppelin/pull/2717
Tried FireFox-56, it works, is failing with some of the flaky tests
(https://api.travis-ci.org/v3/job/326228047/log.txt,
https://api.travis-ci.org/v3/job/326219155/log.txt)
Along with that build
(https://travis-ci.org/prabhjyotsingh/zeppelin/builds/3262280430) is also
failing for profile 6-10 with:
```
ZeppelinSparkClusterTest.sparkRTest:208 expected:<FINISHED> but
was:<ERROR>
```
which is not related to this.
