[Bug 1405874] [NEW] firefox plugin-container is using too many CPU cycles

[Dan Volkman]

Public bug reported:


Quick fix: Don't leave Firefox running when not in use.


Reboot
sign in and start Firefox
goto youtube.com and watch any video
start xterm(1) run top(1) you will always see plugin-container near or at top
or
let system sit for a while or overnight
# ps -ef | less
look at the "TIME" field
or you could use
# ps -ef | sort -t: -nr -k3 | head -1
to see it sorted  by TIME field
and for me this is returned:

dan      17148 15252 27 13:36 ?        00:59:04 /usr/lib/firefox/plugin-
container /usr/lib/flashplugin-installer/libflashplayer.so -greomni
/usr/lib/firefox/omni.ja -appomni /usr/lib/firefox/browser/omni.ja
-appdir /usr/lib/firefox/browser 15252 true plugin

And this program far out strips all other programs using CPU TIME, also
it is causing a slight load.
