Description of problem:
SELinux is preventing /usr/lib64/thunderbird/thunderbird from using the 'ptrace' accesses on a process.

*****  Plugin catchall_boolean (89.3 confidence) suggests   ******************

If 您要 deny any process from ptracing or debugging any other processes.
Then 您必须启用 'deny_ptrace' 布尔值告知 SELinux 此情况。
您可以阅读 'unconfined_selinux' 手册页面来了解详情。
Do
setsebool -P deny_ptrace 0

*****  Plugin catchall (11.6 confidence) suggests   **************************

If 您确定应默认允许 thunderbird ptrace 标记为 unconfined_t 的进程。
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 thunderbird /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
