SELinux is preventing /usr/lib/nspluginwrapper/npviewer.bin from unlink access on the file /home/tom/.macromedia/Flash_Player/macromedia.com/support/flashplayer/sys/settings.sol.

*****  Plugin restorecon (99.5 confidence) suggests  *************************

If you want to fix the label, settings.sol does not have the default system label.
Then you can run restorecon.
Do
# /sbin/restorecon -v /home/tom/.macromedia/Flash_Player/macromedia.com/support/flashplayer/sys/settings.sol

*****  Plugin catchall (1.49 confidence) suggests  ***************************

If you want to allow npviewer.bin to have unlink access on the settings.sol 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 /usr/lib/nspluginwrapper/npviewer.bin /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
