Description of problem:
as i start firefox, it allways happens
SELinux is preventing /usr/lib/nspluginwrapper/npviewer.bin from 'append' accesses on the file C:\nppdf32Log\debuglog.txt.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that npviewer.bin should be allowed append access on the C:\nppdf32Log\debuglog.txt 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 npviewer.bin /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
