Description

[siarhei_simanovich]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/60.0.3112.113 Safari/537.36

Steps to reproduce:

I load an web app that open second browser window to show useful data.
On web app there is unload event listener that closes additional window.



Actual results:

When I close exact tab, unload event fires and close additional.
When I close browser completely, unload event didn't fired and on next browser start it load original web app and additional browser window. Additional browser window is trying to close self (cause missing data), but can't with following error: "Scripts may not close windows that were not opened by script."


Expected results:

When I close browser, on web app unload event should fire and on next start I shouldn't see additional window.

Can you attach link to the web app for reproducing?

How do you "close browse completely"? Did you close via cmd+Q?

Does additional browser window try to close itself _at the beginning of browser restart_? Does the missing data result from not being closed by unload event listener?

Unfortunately no, you can simple use window.open() to reproduce case.

Additional data was grabbed from reference window.opener, since after restart this prop is not available, additional window perform window.close() and got error above.

JSEventHandler does call the 'unload' event handler [1] during browser termination. Keep checking why browser termination hinders the event handler's execution.
