Must Have Thunderbird Add-ons for MS Outlook Users

I have been using Mozilla Thunderbird as my email client for quite some time now on my Ubuntu box & have been more than happy with it.  This post talks about a few add-ons that made my experience with Thunderbird all the more enjoyable. Read on……

The first thing that you miss with a plain Thunderbird installation is when somebody sends you a meeting invite. With Outlook it was pretty straight forward – you hit the accept button & you get the entry in your calendar which shows up a pop up at the right time to remind you of the event. Lightning adds just that functionality to Thunderbird. Once installed you get a calender & tasks interface which are pretty easy to use.

I remember when I started using Thunderbird, one functionality that I used to hate was that it used to open a Response or Forward in a new window leaving the original email message still open. After sending a response I was required to close the original message window as well. Now this was pretty annoying to me. However a simple add-on called Buttons! came to my rescue. It allowed creating new set of buttons (Reply!   Reply All!    Forward!) to my email message windows and using these instead of the regular ones gave me the desired effect of automatically closing the email message on hitting the Reply/Forward button.

Besides the above two add-ons, I have also been using a simple add-on called “Display Mail User Agent” that I like. This one simply displays the user Agent (email client) used by the email sender. This neat add-on displays a nice logo in the header of the email message depicting the client used. To download or know more about this add-on, please visit
