Firefox & Thunderbird Instability in Xenial

Hi Jordan,

The only files being updated by Firefox and Thunderbird are in /tmp and 
$HOME/{.cache,.mozilla,.thunderbird}.  Since I am filling out crash 
reports daily that go to Mozilla, I'll assume that they will contact me.

I switched to Midori and Claws-mail as an experiment.  Stable although 
not as feature rich.

I also tried an alternate distro (Ubuntu MATE) on a 3rd machine (AMD64 
type with lots of RAM).  I get occasional crashes there too. My gut 
tells me that Mozilla common code for Firefox and Thunderbird has some 
environment nuances if you aren't seeing it too.  This is the first time 
that I have ever had trouble with Firefox and Thunderbird.  I may try 
Chrome too.
