"Unresponsive script dialog" is as follows:

>A script on this page may be busy, or it may have stopped responding.
>You can stop the script now, or you can continue to see if the script will complete.
>
>Script: http://www.eurogamer.net/scripts/Eurogamer/jwplayer/jwplayer.js?v11.0.5.2:1

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.
