Mozilla has released an updated patch for Mozilla Thunderbird for tabbed message browsing. Developed by Myk Melez, the feature allows users to right-click a message header and select "Open Message in New Tab" from the context menu.

Users occasionally want to keep a particular message open while browsing their mail, open multiple messages simultaneously for quicker reading of messages over a slow network connection, or otherwise access multiple messages at the same time. Thunderbird currently supports this with its "open message in new window" feature, which displays one or more messages in separate windows.
