Let me start by saying that I am doing something rather unorthodox with jQuery, and I realize that this is probably outside the realm of what is reasonable.
I have a 65x65 HTML table, giving me 4225 TD cells. I am making each of them clickable with the following code: $('td').click(function () { // do something }); It works wonderfully in all browsers (well, IE is a little slow, but it's IE). When I go to close this page, Safari and Opera close almost instantly, IE pauses for a moment and then closes, but Firefox takes sometimes 10 seconds or more to close the tab, causing the browser to lock for that time. I traced the lock into the jQuery cleanup code for event handling. Does anyone know why this is so slow on Firefox?
