I can confirm the newly-opened (by multifox) window has the same Google credentials as I have in the window from which I spawned the second multifox window.

The developer has been contacted through AMO.

I think I'll wait for the availability of a more comprehensive documentation.

Is there anything in particular that you think is missing from the docs?

For example: https://developer.mozilla.org/en-US/docs/Observer_Notifications

Where observers for "http-on-modify-request" or "document-element-inserted" should be placed? Chrome or frame script?

Jeferson, the MDN documentation is still in flux. This MDN page has an e10s code example using "http-on-modify-request" (in chrome script) and mentions "document-element-inserted" (in frame script):

https://developer.mozilla.org/en-US/Firefox/Multiprocess_Firefox/Pitfalls_for_add-on_developers

HTTP networking happens in the chrome process. Document changes happen in the content process.

If you have any other e10s questions, just drop by the #e10s IRC channel on irc.mozilla.org (https://wiki.mozilla.org/IRC).

Glad to see new documentation!

It seems I'll need to wait until bug 1108827 gets fixed, because currently there is no equivalent method for
httpChannel.notificationCallbacks.getInterface(Ci.nsILoadContext).associatedWindow

(Something like nsIHttpChannel.associatedInnerWindowID would be enough!)

With Firefox 57 only WebExtensions are permitted and are, by default, e10s compatible.
