Both Firefox & Thunderbird stopped working thing morning.  I was using both all morning, but neither work now.  I noticed there were 2 updates just before this happened.  This affects both my desktop and notebook computers.

Rebooting does not help.

Here are the errors I get when I try starting from the command line:

Any ideas?

tnx jk

BTW, I'm sending this email from Windows, where both Firefox and Thunderbird work.
