1387863 - opening windows from custom xul app failes since firefox 53

Status: RESOLVED WONTFIX

(Core :: Window Management, enhancement, P3)

Description

[Stefan Schneider]

What did you do?
================
My browser -app with a custom xul and embedded <browser type="content-primary"> page runs within firefox =< 52.
(example command: /Applications/Firefox.app/Contents/MacOS/firefox -app "../../app/seb.ini" -profile "../../../profilemac2" -purgecaches)

Links to new windows from browser.contentDocument are opened within the defined custom browser.chromeURL and toolkit.defaultChromeURI and requests are automatically assigned to the embedded xul browser.


What happened?
==============
Since firefox >53 (on any OS) this does not work anymore. The browser.chromeURL seems to be opened in the background, no window is rendered anymore and the requested url is not assigned to the content-primary browser anymore.



What should have happened?
==========================
the window should be rendered and the request url should be loaded in to the content-primary browser of the custon xul page.
Maybe it is not supported anymore in current firefox versions or is there any workaround?


Is there anything else we should know?
======================================
