I'm using the same Seam version as you but I can use back button in both IE and Firefox (and if you look at Seam examples, they should all work with back button). So it seems to be something IE specific in your case (i.e. some weird javascript). Do you observe it in all pages of your app or only in some of them? It's difficult to say more without any source code... View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4023014#...
