Thunderbird keeps on expanding the list of partners for Thunderbird Filelink: we are pleased to announce that Box.com now joins YouSendIt and UbuntuOne in the list of tightly integrated online storage service partners. With Thunderbird Filelink, sending large files is no longer a pain. Simply select the file you want to attach and tell Thunderbird you want to link it: as soon as the file is uploaded to Box.com, you are ready to send this big file that would never have made it through. Even better, we believe that Box.com online document collaboration services will nicely enhance the way you share files over email, and as a Thunderbird user you’ll get 25GB storage space for free.

Also, Thunderbird is permanently updated with new features and security improvements. To make the update experience even smoother, Thunderbird now supports silent background update. As soon as an update becomes available, Thunderbird downloads it and apply updates in the background. You’ll be up and running very quickly with the latest and greatest Thunderbird the next time you start. If you are curious, the silent background update eliminates the need for the update progress dialog on all platforms and eliminate the nagging User Access Control dialog on Windows.

We hope you will enjoy it and do let us know your comments!

Reminder: The Thunderbird 3.1.x series and earlier versions are no longer supported and therefore are becoming more exposed to Internet security threats. We recommend that all Thunderbird users of previous versions upgrade to the latest release as soon as possible.
