keeping chrome firefox and safari synced is hard. browser wars are good. and bad. now with the launch of a dev build of chrome for the mac and linux there is now a decent choice of fast browsers on mac. one problem is how to keep all the data synced between all the browsers.
I use safari, firefox and now chrome on my mac and I use ie7, ie8, firefox, safari, opera and chrome at work (im a web developer – I need to check it all works properly)
