Generally speaking, this is not allowed. Many people have posted their tricks for it over the years on the mozillaZine web development forum, so you might search there:

Thanks For your reply but here in the provided link http://forums.mozillazine.org/viewforum.php?f=25 .I am not finding the solution.So it would be better to directly post the answer here itself. Actually I know it is not possible close the window until unless they opened by script,But if you have any other suggestion about this so i can implement and that will meet the requirement as well. My requirement is when I will click the CLOSE button that time it has to close that application tab in firefox.This feature is pretty working in the other browser well except in the firefox only.So i hope if there is another way to fulfill this requirement.Thanks in advance once again. Please have a look at this program Here i written a simple program for closing the window and this is working well in other browser as i tested but not in firefox .....

<meta content="text/html;charset=utf-8" http-equiv="Content-Type"> <title>Hello World!</title> <title>Closing the Window...</title>

Close the Window...

<input onclick="window.open('','_parent',''); window.close();" type="button" value="Close">

When you run window.open() into _parent, you are navigating the current window to a different page, thus unloading the page containing your running script. I think Firefox may be terminating the script when you unload the page in which it is running.
