Conversations add-on brings a Gmail-like experience to your Thunderbird 3.3 inbox
A new add-on from Mozilla Labs brings a richer threaded view to Miramar. Once installed, clicking a collapsed thread in your inbox causes the entire conversation to load in Thunderbird's reading pane. Unread messages are expanded and those you've previously read are collapsed -- just like Gmail. Buttons are also added to reading pane which allow you to expand or collapse all messages or pop the conversation out into a new tab.
Check out Mozilla's demo video after the break to see Conversations at work, or download the necessary bits and give it a go yourself!
