:wennie - this test appears to be failing at intermittent rate greater than previously when migrated over from macosx1010 to macosx1014. As you are the triage owner, could you take a look at this case, or redirect the ni to someone who may be able to comment? I am proposing that while the investigation happens, that this test case be disabled for macosx1014.

This no longer seems to occur according to Orange Factor. I assume it was fixed in some other bug or maybe the test got disabled. Can we close this "worksforme" at this point?

Test is not disabled according to https://searchfox.org/mozilla-central/source/docshell/test/iframesandbox/mochitest.ini

Since there are no failures since August, closing as wfm. Thak you.
