I started to use of Mozilla Thunderbird since April 2011. Before that, I used Microsoft Outlook 2007. I am really happy with all features of Mozilla Thunderbird but, eager to install facility of task manager. But, I just brows Mozilla projects & found this great add on to get it done. Thanks Mozilla to make my internet stuff very easy!!This review is for a previous version of the add-on (1.0b2).
