Thanks Jeffery,
The edit in post #3 is working here.
I used chmod to the .so file then let my user ID edit the file and chmod back to 644.
For some reason Okteta as root was slow slow slow.
As a test I booted to an older partition with Ubuntu 12.04. Started Firefox - no bug file on desktop. Ran update-manager. Started Firefox - with just home page, no pdfs loading and the bug file appeared on the desktop. Bug also present on my spouse's laptop. Fix worked there too.
