How can I close a window with Javascript on Mozilla Firefox 3

Question

I need to close the tab which displays my webpage  by the click of a button  But firefox does not allow to close the window by javascript as long as it is not opened by javascript  If I set the value of dom allow scripts to close windows to be  true   then even normal window close   works too  But that is not a good solution      I tried the following workaround suggested in one of the forums    lt script language  javascript  type  text javascript  gt  function closeWindow        window open      parent          window close       lt  script gt     It is supposed to fool the browser into thinking that it was actually opened by javascript  but this does not work in Firefox 3   Can anyone please suggest a workaround

This code works for both IE 7 and the latest version of Mozilla although the default setting in mozilla doesnt allow to close a window through javascript.

Here is the code:

function F11() { window.open('','_parent',''); window.open("login.aspx", "", "channelmode"); window.close(); }

To change the default setting :

1.type"about:config " in your firefox address bar and enter;

2.make sure your "dom.allow_scripts_to_close_windows" is true

If the browser people see this as a security and or usability problem  then the answer to your question is to simply not close the window  since by definition they will come up with solutions for your workaround anyway  There is a nice summation about the reasoning why the choice have been in the firefox bug database https   bugzilla mozilla org show bug cgi id 190515 c70  So what can you do   Change the specification of your website  so that you have a solution for these people  You could for instance take it as an opportunity to direct them to a partner   That is  see it as a handoff to someone else that  potentially  needs it  As an example  Hanselman had a recent article about what to do in the other similar situation  namely 404 errors  http   www hanselman com blog PutMissingKidsOnYour404PageEntirelyClientSideSolutionWithYQLJQueryAndMSAjax aspx

From a user experience stand-point  you don t want a major action to be done passively    Something major like a window close should be the result of an action by the user

For security reasons  your script cannot close a window tab that it did not open   The solution is to present the age prompt at an earlier point in the navigation history   Then  you can choose to allow them to enter your site or not based on their input   Instead of closing the page that presents the prompt  you can simply say   Sorry   or perhaps redirect the user to their homepage
