Open a page in various ways, and then use window.close() to close it. The performance is different in each browser. For example, when you enter the URL directly in the address bar, calling window.close() in Firefox Chrome Safari to close the page has no effect. Another example is the window opened by Ctrl clicking on the link. In Firefox, it cannot be closed by calling window.close().

The differences are as follows:

serial number	Close Code	Requires confirmation	No effect	No need to confirm	Test

	Enter the URL in the address bar	Click the link	Ctrl key click the link	window.open	window.showModalDialog
IE6	Prompt window to close	Close directly	Close directly	Close directly	Close directly
IE7/8	Close directly	Close the prompt window	Close the prompt window	Close directly	Directly Close
Firefox	Do not close, no prompt	Close directly	Do not close, no prompt	Close directly	Close directly
Safari	Do not close, no prompt	Close directly	Close directly	Close directly	Close directly
Chrome	Do not close, no prompt	Close directly	Close directly	Close directly	Close directly
Opera	Close directly	Close directly	Close directly	Close directly	Not supported

Cannot be closed under firefox Possible reasons:

It is not a problem with the JS code window.close(), but The solution to the Firefox configuration problem is as follows: Enter about:config in the Firefox address bar. Find dom.allow_scripts_to_close_windows in the configuration list, right-click and select Change the above false to true. Note: The default is false, which is to prevent the script from closing the window randomly

Attached code: window.opener = null;//In order not to appear the prompt box window.close();//Close the window

The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.
