Rated 3 out of 5 stars

There still doesn't seem to be a way to set the manager to open/focus on an existing window, which is one reason I switched to Gmail Notifier until it recently broke, for the last time. "Existing Window or Tab" does not switch to that tab, it just reloads that tab in the background, which is not only pointless, but annoying because it closes active chats when you reload the page. It should just bring that tab to focus (or there should be an additional option to do so).

Edit: arg, I see this extension is no longer supported either. Frustrating.

This review is for a previous version of the add-on (0.6).
