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: firefox ATTENTION: default value of option mesa_glthread overridden by environment. ATTENTION: default value of option mesa_glthread overridden by environment. ATTENTION: default value of option mesa_glthread overridden by environment.
