How To Change Themes In Mozilla Thunderbird


mozilla-thunderbird-feature-imageAs always, I love to change the look of programs; you need to make it your own and show your personality!  As in some of my other articles, “How To Change Twitter Theme Colors,” “How To Change Facebook Colors In Chrome,” and “How To Change YouTube Channel Art,” I found a new way you could leave your mark. Saying that, I have figured out how you can add a touch of you to your Mozilla Thunderbird eMail client.

I was sitting at work one day and, with holidays here, I was feeling festive. As I was looking over some eMail I noticed that Thunderbird was not looking very festive. Then a little light bulb clicked on over my head and I knew I had to figure out how to change that. I did a little research and now I’m going to share how you can spice up that eMail application to better reflect you. Plus, it is great being able to change the Theme to keep you smiling year ’round. Are you ready?

Change The Themes in Thunderbird

Note: This works in Thunderbird Versions 45.5.1, 45.5.0 and 45.3.0

Step 1: Open Thunderbird and head up to the Tools option at the top. Click it

Step 2: A menu will appear and you will want to select Add-Ons from the menu

Step 3: Once you do this you will be in the Add-ons Manager tab. You should be on the Get Add-ons screen and if you aren’t, then select Get Add-ons from the left menu


Here you will want to look to the right side and you should see a box labeled Featured Themes. You will want to click on the link next to this title— See all.

Step 4: This will bring up the Themes tab where all the themes are located. To the left, you will see Themes broken up into categories: Most Popular, Top Rated and Recently Added. If you are bold enough, you can scroll down some and click the Submit a New Theme button, but we will not be covering that in this article.

Step 5: Now browse through these and choose the one you want. I chose “Snowmen in Winter” from the Holiday Top Rated section because it is fun. To add it, click on the image

Step 6: On this screen you have to click the green button, Add to Thunderbird

Step 7: Some of you might see this pop-up at the top once you hit the green button.  This is making sure you want to allow the theme to apply to Thunderbird. Click Allow


Step: 7.1: Now you will see another bar appear at the top. This tells you that your new theme has been installed which you can see in this picture. If you are happy with your choice, you can click the X next to Manage Themes on the right. It also gives you two options: one being Undo, and the other being Manage Themes. Now, if you are not happy, click Undo. This will change it back to what you had before. Let’s click on Manage Themes and see what this does…

Step 8:  After clicking the Manage Themes button you will be taken to the Appearance window under the Add-ons Manager Tab. Here you will see all the Themes you have installed. From here you can Disable them or Remove them altogether. You can get to this same area by clicking the Appearance option on the left when you are in the Add-ons Manager tab.

Here is my end result from installing the Snowmen in Winter Theme in the Thunderbird eMail program.

I tested this with three different versions of Thunderbird and all worked the same. Depending on your version of Thunderbird, it could be different from what you have been shown. At least I can say it works on these versions and now you can make your Thunderbird look more fun from now on.

What theme did you choose?
