Wide World of Women

If I go to the baseball reference site and click the managers section, the page comes up fine but if I try to resort the table I get a long freeze and then a message saying that the script stopped running.
This only happens with firefox and only with that section of that site.
I don't know if it's due to the large data or what but all I do know is it was fine a few months ago then it went back to this pause/script issue again

Hmm, the table re-sorts quickly for me on Safari (Mac 10.4.11). Not sure what it is.
