[GRLUG] Could not initialize application's security component (Firefox)

[Eric Beversluis]

Got it. Google is my friend after all.

support.mozilla.org/en-US/kb/couldnt-initialize-applications-security-component:
Problem seems to be a corrupted cert8.db file. Includes info on getting
to "containing folder", which on my install is helpfully called
'xym05ck7.default'.

I even re-did the SELinux disable steps and Firefox still seems to be
working.

Thanks to all.
