Firefox 68 does not read configuration from /etc/firefox/pref

Solution Unverified - Updated -


Firefox does not read configuration anymore from /etc/firefox/pref.

For example having a /etc/firefox/pref/autoconfig.js is not read on firefox start, only the system dedicated folder /usr/lib64/firefox/defaults/pref is parsed.
