events.js attaches 'unload' in all browsers, breaking Firefox/Safari/Opera bfcache
Reported by Stephen Elson | July 17th, 2009 @ 01:21 PM | in 1.6
Firefox 1.5+, Safari 3/4 (probably 2.0 too), and Opera have a back-forward cache that is disabled if an unload event is attached. Navigating back/forward is slower without the cache.
This should probably run IE-only, or IE-only and FF2 only:
r.addListener(window, "unload", clearEvents);
I don't think it's necessary in IE8 (when run in IE8 mode? or both IE8/IE7 mode?), because the garbage collector should work there.
At least some versions of Firefox 2 have an unrelated bug where events must be cleaned up:
http://dev.jquery.com/ticket/1911 - "it appears the events are being retained on page unload and that is causing the issues."
