Goes to the previous page in session history, the same action as when the user clicks the browser's Back button. Equivalent to history.go(-1).

void back();

Goes to the next page in session history, the same action as when the user clicks the browser's Forward button; this is equivalent to history.go(1).

void forward();

Loads a page from the session history, identified by its relative location to the current page, for example -1 for the previous page or 1 for the next page. When integerDelta is out of bounds (e.g. -1 when there are no previously visited pages in the session history), the method doesn't do anything and doesn't raise an exception. Calling go() without parameters or with a non-integer argument has no effect (unlike Internet Explorer, which supports string URLs as the argument).

void go(int distance);

Pushes the given data onto the session history stack with the specified title and, if provided, URL. The data is treated as opaque by the DOM; you may specify any JavaScript object that can be serialized.  Note that Firefox currently ignores the title parameter; for more information, see manipulating the browser history.

void pushState(Object data, String title, [String url]);

Updates the most recent entry on the history stack to have the specified data, title, and, if provided, URL. The data is treated as opaque by the DOM; you may specify any JavaScript object that can be serialized.  Note that Firefox currently ignores the title parameter; for more information, see manipulating the browser history.

void replaceState(Object data, String title, [String url]);
