Similar, or related(?), issue with Firefox and scripts for me too. If I leave an article open for a while a script on the page will go wild and I get a pop-up window asking if I want to debug, stop the script or let the script continue to run ( “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.”). Whether I press ‘stop’ or ‘run’ makes no difference, Firefox crashes either way. I haven’t tried the debug option as I wouldn’t really know what to do…
