Description of problem:
SELinux is preventing plugin-containe from 'name_connect' accesses on the tcp_socket port 8021.

*****  Plugin mozplugger (89.7 confidence) suggests   ************************

If 您要使用 plugin 软件包
Then 您必须关闭 SELinux 对于 FIrefox 插件的控制。
Do
# setsebool -P unconfined_mozilla_plugin_transition 0

*****  Plugin catchall_boolean (10.0 confidence) suggests   ******************

If 您要 allow mozilla to plugin can network connect
Then 您必须启用 'mozilla_plugin_can_network_connect' 布尔值告知 SELinux 此情况。
您可以阅读 'None' 手册页面来了解详情。
Do
setsebool -P mozilla_plugin_can_network_connect 1

*****  Plugin catchall (1.69 confidence) suggests   **************************

If 您确定应默认允许 plugin-containe name_connect 访问 port 8021 tcp_socket。
Then 您应该将这个情况作为 bug 报告。
您可以生成本地策略模块允许这个访问。
Do
请执行以下命令此时允许这个访问：
# grep plugin-containe /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
