This looks to be a perma failure for Marionette tests as run on Ubuntu 16.04 and fails in both e10s and non-e10s mode. https://treeherder.mozilla.org/#/jobs?repo=try&revision=53035f0f9847

Ting-Yu, given that you did most of the work on this specific test, would have mind to have a look what could be broken with this test when using Ubuntu 16.04 for Marionette tests? Thanks.

Screenshot as taken by Marionette for this failure.

I can reproduce this locally.

Try result with the patch "Bug 1315760 - Use Ubuntu 16.04 docker image for Marionette tests." https://treeherder.mozilla.org/#/jobs?repo=try&revision=373d36c1e064ccd0ab46f8800bff93d018d32df1
