Attachment: Test case

Test case. This file is opened with window.open('test_case.html');

The popup window is closing properly with Firefox 80.
This stopped working with Firefox 81, and is still not working on Nightly 83.0a1 (2020-09-24)

This bugfix landed on Firefox 81.

I can reproduce. With window.open("print.html") we open a new tab. After canceling the print prompt the tab stays open.
For me in Chrome the tab is immediately closed and no print preview is shown.

I had just filed bug 1667350 for this. This only happens if print() and close() are both invoked before or during onload.

All browsers delay print() until after the load event has fired, see the discussion in https://phabricator.services.mozilla.com/D87898.

We block closing the window if such thing happens, and it seems Chrome doesn't. Unsure about Safari.

It seems before we also "auto-closed" the window after print if needed and now we don't... I'll look at why.

This was only being checked on OnDonePrinting() which isn't called in
the original docshell. Move it to the window because we don't need to
care about document viewers getting closed during print operations,
they're top level browsers that don't run script.

[Tracking Requested - why for this release]: Simple fix for printing regression that affects some sites in the wild, see bug 1667422.

It would be nice to understand how common this pattern is in the wild to aid in deciding whether this needs to drive a dot release or not.

Please nominate this for Beta approval when you get a chance so we can get as much bake time as possible ahead of any dot release decisions.

It would be nice to understand how common this pattern is in the wild to aid in deciding whether this needs to drive a dot release or not.

In our business, we use this in conjunction with auto_print feature.
When user ends processing a parcel, we open a popup with window.print & window.close, to generate a label.
I can't really say if our use is that common, but I think we should not be the only ones to need this feature.
