I keep meaning to tell EP about this, but it always slips my mind... I was accustomed to hitting Alt+S after typing a message in the quick reply box to submit a post. Now I don't remember which version of Firefox changed the access key of the "History" menu item, but there's basically a conflict, and Alt+S now brings up the History menu instead. So EP...when you get a chance, can you change the access key for the quick reply post button to something else? FYI, the letters F, E, V, B, T, H and A are also assigned to menu items in Firefox/IE7, so avoid those as well.
