Make Thunderbird use LibNotify in Jaunty
If you miss the LibNotify functionality in Mozilla Thunderbird and want top have it in Ubuntu Jaunty, all you have to do is install this AddOn. Right click here, select Save As, download the extension and install it through Thunderbird. Restart the application and enjoy the new notification system that will pop up whenever you get new mail.
It might be worth pointing out that you have to disable Thunderbird’s own notifications in order for it to work…
Thanks for the tip!
