Dear friends I have an issue while trying to catch window.onbeforeunload event in Firefox (version. 47 and more).

The problem is that in Firefox window.onbeforeunload works well when I right click on screen and inside the pop-up menu choose "Reload" option.
Whereas it's not working when I:

press F5 or Ctrl + F5 key
click on the Reload button in browser's navigation

Here is my code:

window.onbeforeunload = function (e) {
     e = e || window.event;
     self.video_disconnect();

     if (e) {
        e.returnValue = 'Sure?';
     }

     // For Safari
     return 'Sure?';
};

By the way, I applied many solutions (also from here: window.onbeforeunload and window.onunload is not working in Firefox , Safari , Opera? and from here: Mozilla firefox not working with window.onbeforeunload ) and have searched a lot, but still could not find the appropriate one.
The solutions provided there seems old so I hope there is already new approach for this issue. Thanks!

Check the `note (2)` there regarding firefox. – Dekel Aug 22 '16 at 12:18
which one is that? – johannesMatevosyan Aug 22 '16 at 12:18
are you about this? - In Firefox you MUST do some real interaction with the page in order for this message to appear to the user. – johannesMatevosyan Aug 22 '16 at 12:19
Yes, exactly this. – Dekel Aug 22 '16 at 12:20
could you ne more specific? what means real interactions? any examples? – johannesMatevosyan Aug 22 '16 at 12:22
If you will not click inside the page - the `onbeforeunload` function will do nothing. You must do some real-user-interaction with the page (if you just enter the page, and then do a refresh (f5/ctrl+f5) - the `onbeforeunload` function **will not** be called). – Dekel Aug 22 '16 at 12:24
Does it gives you the answer you were looking for? – Dekel Aug 22 '16 at 12:39
Thanks for your response, I will check a bit later and will let you know. By the way you could write your answer below. – johannesMatevosyan Aug 22 '16 at 12:46
