Re: [K12OSN] Firefox and load average



final update on this:  As a hack to fix this, I copied the files that
seem to change depending on which server is being used to a folder,
and created a login script which simply puts the correct version of
the files in each user's .mozilla/firefox/*.default directory upon
login. With this hack, the delay/lag launching FF is gone. Of course
I'll probably have an issue when I upgrade FF but for now it is
mitigated and I'll have time over the holidays to try and sort it out
better.
