Today, the folks over at Growl released official extensions for both Thunderbird and Firefox. You can now be alerted when new mail arrives or when downloads complete.

Install is extremely simple, just install the extension. That’s it. You can configure how it displays though the main Growl system preference just like any other application. It’s simple and sweet. I’ve been using them both all day and they are a great addition to the Mac platform.
