It's the first time Fx has crashed in that manner. Crashes are very rare 
anyway, so I'll keep those pref changes in reserve in case it starts 
happening more frequently.

The home page is blank.

Shift - Open doesn't start Fx in safe mode in Linux Mint. It can be 
opened in safe mode from a terminal.

As I mentioned above, Fx has been very stable and even if it has crashed 
before it has been easy to restart. It's just because it wouldn't 
restart this time that I posted here.
