Shane, looks like https://bugzilla.mozilla.org/show_bug.cgi?id=1558326#c13 isn't fixed. Could you take a look over this? Thank you.

Th link: https://treeherder.mozilla.org/#/jobs?repo=autoland&group_state=expanded&selectedJob=272178153&resultStatus=testfailed%2Cbusted%2Cexception&classifiedState=unclassified&searchStr=os%2Cx%2C10.14%2Cdebug%2Cmochitests%2Ctest-macosx1014-64%2Fdebug-mochitest-browser-chrome-e10s-4%2Cm%28bc4%29&revision=1e85f7fb21f682d73b44fa13c9a11b7f65602018

Let see if that does it...

My fix doesn't seem to fix this completely, perhaps we just re-disable the test on osx-debug, I have higher priority things I need to do right now.

Ok, will disable the test on osx debug. Thanks.
