IE6	提示窗口关闭	直接关闭	直接关闭	直接关闭	直接关闭
IE7/8	直接关闭	提示窗口关闭	提示窗口关闭	直接关闭	直接关闭
Firefox	不关闭，无提示	直接关闭	不关闭，无提示	直接关闭	直接关闭
Safari	不关闭，无提示	直接关闭	直接关闭	直接关闭	直接关闭
Chrome	不关闭，无提示	直接关闭	直接关闭	直接关闭	直接关闭

Possible reasons for not being able to close under firefox:

It is not the problem of JS code window. close (), but the configuration problem of Firefox. The solution is as follows: Enter about in the address bar of Firefox: config, find dom.allow_scripts_to_close_windows in the configuration list, and right-click the switch to modify the above false to true. Note: The default is false to prevent scripts from closing windows indiscriminately

Additional code: window. opener = null; //To avoid the prompt box window. close (); //Close the window
