All extensions disabled due to expiration of intermediate signing cert

Interesting coincidence, my Ubuntu 12.04 Let's Encrypt certbox-auto updated in March 2019 to a version which no longer runs on Ubuntu 12.04 without major surgery.

I wonder if this bit Mozilla and caused this issue.

I can beat that. I had a Let's Encrypt cert renewal that upgraded python and itself and borked the system it was running on.
