The following was filed automatically by setroubleshoot: Summary: SELinux is preventing firefox (sandbox_t) "open" etc_t. Detailed Description: SELinux denied access requested by firefox. It is not expected that this access is required by firefox and this access may signal an intrusion attempt. It is also possible that the specific version or configuration of the application is causing it to require additional access. Allowing Access: You can generate a local policy module to allow this access - see FAQ (http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Or you can disable SELinux protection altogether. Disabling SELinux protection is not recommended. Please file a bug report (http://bugzilla.redhat.com/bugzilla/enter_bug.cgi) against this package.
