Ive been using firefox for ages, and added the greasemonkey addon to run scripts aswell, my mate wrote this nice little script for greasemonkey, thought id pass it on - http://userscripts.org/scripts/show/9138
it adds pretty much realtime countdown to items with about 24hrs less to run, so you can then time a bid right near the end
