Re: [K12OSN] Sky high load average with FF and CentOS?



Hi,
FF3 under certain situations can devote a decent amount of cpu when the
history sidebar is open.

Also, if anyone knows how to install the adblock plugin across all the
users, that'd be helpful in cutting down flash ads and unnecessary
graphics.
Regards,
William
