I prevent a backspace button conditionally using confirm box. i used event.preventdefault() method to stop the event of i press ok in the conform box. But it works when the focus is on either input or text area elements. if there is no focus in these controls the browser redirects to previous page.

i need your help.. thanks in advance !

Note that you can disable the backspace button action to go back or forward in the history in Firefox by setting the browser.backspace_action pref to 2 on the about:config page.
