Firefox & Thunderbird Instability in Xenial

[Richard Elkins]

Is anyone else having issues with Firefox and Thunderbird on Xubuntu 
Xenial?  I am getting random crashes almost every day from one or the 
other, leading me to believe that it is a set of issues in common code.  
I reported it here: 
https://bugs.launchpad.net/ubuntu/+source/thunderbird/+bug/1581569
and in the Mozilla pop-up whenever I get it.

My 14.04 server has no such Mozilla issues even though the Firefox & 
Thunderbird versions are the same as what's on the 16.04 system.

If anyone else is having such an experience, please mark that "it 
affects me" at the bug report.

If anyone has a work-around, please add a comment to the bug report.

Thank you.
