It's not just ESPN...
Same Firefox/Safari problem, same "started when I visited ESPN.com," but it also causes a lock-up when I visit the LA Times web page. Exceedingly annoying, but an example of the value of the internet--twenty years or so ago, I would have been staring at a wall wondering why my computer suddenly failed. One quick Google search lead me to this thread, and I see that misery really does love company. Any solutions other than the javascript disabling, which I'm not clear whether it works?
