Just installed this plug-in to access hangouts in Mozilla browser so I don't have to open Chrome simultaneously.

I like that this plug-in opens in a separate pane out my browser. Its fast and responsive. Just installed so far so good!

Very nice plug in. It's replacement of chrome extension. Furthur impression may be later.

Works as advertised.

Just what I was looking for! Standalone hangouts. It would be great of the messages panel could span the full remaining width as the standard hangout chat windows are tiny.
