on my constantly updated FC5 system, on a regular basis, a new firebox window will be created but with nothing more than the very top title bar and nothing else -- no tool bar, no menu bar, no google bar, no scrollbar. and when that happens, deleting that window blows away all firefox clients on the system. so i start over and, a day or so later, it all happens again. i've seen notes regarding a memory leak in firefox. is anyone else seeing this behaviour? thanks. rday
