Description of problem:
SELinux is preventing 57656220436F6E74656E74 from 'create' accesses on the file registry.x86_64.bin.tmp01AK9X.

*****  Plugin mozplugger (99.1 confidence) suggests   ************************

If you want to use the plugin package
Then you must turn off SELinux controls on the Firefox plugins.
Do
# setsebool -P unconfined_mozilla_plugin_transition 0

*****  Plugin catchall (1.81 confidence) suggests   **************************

If you believe that 57656220436F6E74656E74 should be allowed create access on the registry.x86_64.bin.tmp01AK9X file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep 57656220436F6E74656E74 /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
