1131313 - outer-window-destroyed notifications aren't received in a frame script when a browser gets destroyed with e10s off

Status: RESOLVED DUPLICATE of bug 1126089

(Core :: DOM: Core & HTML, defect)

Description

[Matthew N. [:MattN]]

Attachment: Testcase

Listening for outer-window-destroyed from a frame script doesn't work when e10s is disabled. Notifications are received but none have the matching outerWindowID from content.QueryInterface(Ci.nsIInterfaceRequestor).getInterface(Ci.nsIDOMWindowUtils).outerWindowID;

I get a notification with a matching outerWindowID when e10s is on though.

I we decide not to fix this then https://developer.mozilla.org/en-US/Firefox/Multiprocess_Firefox/Limitations_of_frame_scripts#Observers_in_the_content_process should be updated.

so we kill the frame script before the relevant outer-window-destroyed is fired?

Yeas, I think that's what I saw IIRC.

I'm actually working on this right now Gabor.

Whoops, sorry about that, I though this was the one you wanted to hand it over to me...

Bill, should this be fixed by bug 1126089? should we dupe it?
