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

[James P. Kinney III]

Hi William!

Try installing adblock at the proxy filter instead.
http://notes.ozmonet.com/index.php?title=Network-Wide_Adblock
This will use the adblock filter list and squid/squidguard to block the
adds for the network.

I may have to look at making that a default plugin for squidguard
installs :-)
