security updates causing firefox trouble?

[jackson byers]

after checking ok on security updates in my f10,
I am experiencing trouble with firefox; cant seem to go to other sites,
even tho i can still get new gmail.

I also see intermittent jumps in firefox %cpu   to 10-15% range
I dont recall getting updates finished  screen.


It looks like the yum update process is stalled:


[root at f10 ~]# ps ax |grep -i firef

is it safe to :
--quit firefox?
--kill the  8024 python.....yum process?

advice?
