I don't actually get the unresponsive script dialog, but I can tell the browser is unresponsive for a longer period of time than previous versions. According to Shark, about 60% of the time is in fun_getProperty. Brian, does that ring a bell wrt to removing getFunctionPrivate?
This may be related to bug 710780 (logic bug in fun_getProperty).
Alice, can you retest this now that bug 710780 is fixed? I'm not sure I can reproduce it locally, so it's hard for me to tell if it was fixed.

I cannot reproduce problems of Bug 707643 and bug 710780 anymore. So, I mark this as duplicate. http://hg.mozilla.org/mozilla-central/rev/2afd7ae68e8b Mozilla/5.0 (Windows NT 6.1; WOW64; rv:11.0a1) Gecko/20111220 Firefox/11.0a1 ID:20111220031159
