If you're a fan of Mozilla's mail software, Thunderbird, then you might want to update to the latest version that has just been released. Mozilla have pushed out Thunderbird 15, and with it, includes a refreshed visual dash of paint.
Mozilla wants to share the look between their apps, meaning that Thunderbird now sports a more Firefox-like UI, which is a good thing. Thunderbird 15 also includes live chat, where you can skip waiting for that next e-mail, a Do Not Track option for web searches, and finally, the choice of using Ubuntu One cloud storage for large attachments.
