Subject RE: online/offline Events

In lib/common/plugin/network.js on Line 49

            if (info === "none") {

Am I wrong or will this statement never be true since the plugins return the connection as
"Connection.NONE"?

What I'm seeing is that the event online is fired as Connection.NONE is passed in

The spec says to fire an online event whenever the connection type changes, and to fire an
offline event only when you lose your connection. It's not the most obvious, but probably
your multiple event firing is working as intended.

To answer your second question, I think what you're looking for is navigator.onLine. It's
derived from the connection type here:
