Comment 15 for bug 1652272

Oh dear, I am now awfully confused. I will have to do some more testing on this matter later on, maybe I will test it in Safe Mode for a longer time this time. For the issue has returned even though the Ghostery has been removed and GNotify disabled. When I closed the browser the same thing happened as before as well and I got this:

console.error:
