bp-58d624e5-de9a-4e96-8025-79c381170816 The system is an Raspberry Pi 3 with Ubuntu Mate 16.04 installed via BerryBoot. I already tried reinstalling with `sudo apt purge firefox; sudo apt install firefox`, clearing profile with `rm -rf .cache/mozilla .mozilla`, and running Firefox in safe mode with `firefox --safe-mode`. Firefox won't start, and display crash reporter immediately. This problem began to appear on Aug 15, 2017 when Firefox was upgraded to 55.0.1. It didn't occur last week.
