If you turn on gfx-rendered widgets in apprunner (add user_pref("nglayout.widget.mode", 2); to your prefs), you will see that the content window never loads, with the message "Scheduling later attempt to set content window" If you trace it down, you'll find that someone is loading about:blank. Similarly, I want to initialize an empty text field with about:blank instead of using a dummy empty file as I do now, but I get the same sort of hang. You can try this yourself by changing nsGfxTextControlFrame.cpp: - #define EMPTY_DOCUMENT "resource:/res/html/empty_doc.html" + #define EMPTY_DOCUMENT "about:blank"

Changing all Networking Library/Browser bugs to Networking-Core component for Browser. Occasionally, Bugzilla will burp and cause Verified bugs to reopen when I do this in a bulk change. If this happens, I will fix. ;-)
This was fixed long ago.
Bulk move of all Necko (to be deleted component) bugs to new Networking component.
