This function seems to have been deprecated until 3.5.x, and has been removed with Firefox 3.6. I just updated and noticed that problem.
This makes for example the <tr:panelPopup> method non functional. There might be other examples where this function has been used. I think someone who understands javascript good needs to search through the Trinidad sources and replace it with an alternative function? The panelPopup demo page: http://www.irian.at/trinidad-demo/faces/components/panelPopup.jspx works as an example. I am going to open a bug for that, too.
