Yes, I misanalyzed this. It appears that the root cause of the problem was that my content scripts (which run in a sandbox) stopped being able to request chrome:// URLs in FF19. I therefore changed to resource:// URLs. Apparently DOMWindowCreated doesn't fire for a resource:// URL in a browser with type == "chrome", so this is indeed not a FF19 change. This led me to use type == "content" (in retrospect a bad idea) and inject my own XHR implementation. Changing back to chrome:// URLs solves all of this (including eliminating the need to muck with the XHR implementation in the background page) except the original problem of accessing them via XHR in the sandbox. But using the system principal in the sandbox appears to fix this (thanks Brian!). Hopefully I'm all good now with respect to FF19. Thanks for the help.
