 Replying to [comment:21 gk]:
 > Okay, I think the first thing we should do is making sure that really
 the backported patches are the culprit. I guess doing two builds, one with
 the latest tor browser 45.4.0esr code and one where just the backported
 patches are omitted and testing that on 10.11.6 could be a good idea.

 Doing that would be conclusive, although since we do not see the problem
 with TB 6.5a3 it is almost certainly caused by the backported patches
 associated with this ticket.

 > If I did not mess up, hrm. I guess opening a new ticket to track our
 efforts could be helpful. Should we bother with asking Mozilla for help?
 Strictly speaking it is not their issue.

 Probably someone just needs to debug it. Firefox 50 current beta does not
 show the problem. So maybe Kathy and I made a mistake in backporting the
 patches, or maybe there are other fixes in Firefox 50 that avoid the
 problem somehow.
