There it is again: It hangs since at least half an hour now after upgrading. Screenshot attached.
I found, that I have the following entry in /etc/hosts: 127.0.0.9 addons.mozilla.org support.mozilla.org mozilla.org I don't remember, why or when I added this, but probably because of a home phoning issue many years ago. Of course, Firefox should not connect to those sites after upgrade without my consent, right?
