linux npviewer problem

64-bit Firefox npwrapper (npviewer) plugin allows the 32-bit version
of Flash Player run in 64-bit Firefox. But it lock up all the time and
eating CPU cycles all the time.

How to kill npviewer process:
for name in $(ps ux | awk '/npviewer.bin/ && !/awk/ {print $2}'); do kill "$name"; done


Install firefox plugin: noscript or flashblock will solve the problem.


Download 64 bit flashplayer here:
sudo yum install flash-plugin libflashsupport
