<script type="text/javascript">

Yes. But no result in Firefox – rahman_akon18 Mar 07 '16 at 09:58
I dont think Firefox allows custom messages like this – Professor Abronsius Mar 07 '16 at 10:09
What is the solution then ? How can i pop up a message ? – rahman_akon18 Mar 07 '16 at 10:10
`In Firefox 4 and later the returned string is not displayed to the user. Instead, Firefox displays the string "This page is asking you to confirm that you want to leave - data you have entered may not be saved."` https://bugzilla.mozilla.org/show_bug.cgi?id=588292 – Professor Abronsius Mar 07 '16 at 10:14
