Hello was told thunder bird is great to use. I need to know were to downlaod for I mac and if can be used Ipads thanks so much ? does it have block as well for spammers? and for I phones as well?

We tried installing Thunderbird on two PCs, both running Windows 11, but with unsatisfactory results. In July 2025, we bought a 15-inch HP PC running Windows 11. Thunderbird was installed, and the sending and receiving functions worked correctly with one domain name and three email addresses linked to that domain name. In January 2026, we bought a Lenovo T14 PC running Windows 11. We tried installing Thunderbird with the same domain name and three different email addresses linked to that domain name. Result: On the T14, it was impossible to install the third email address; only two addresses could receive and send messages correctly. Furthermore, the 15-inch HP PC now receives messages but can no longer send them; the connection is rejected by the server. Analysis: Apparently, there is an inability to coordinate the two PCs for Thunderbird. Question: Windows 11 had numerous updates between July 2025 and January 2026. Do both PCs need to have Thunderbird installed the same version of Windows 11 ?

Athough you advertise Thunderbird as a free product, your website does not allow me to download it unless I first pay. I am unwilling to pay until I have been able to test the product and verify that it will do what I need it to do.

I'm trying to setup this Thunderbird app on my android phone and in the setup process it wants me to scan i guess a QR code from my laptop with Thunderbird on it. I don't have Thunderbird on my laptop so I can't continue to set the app up on my phone. I need a work,-around for this. I do however have a Mozilla Firefox account and I logged into that but it didn't seem to make any difference

I have a costumer in my store that uses Thunderbird, it has worked fine for him for years without any issues.

But now for some reason random emails get saved to his desktop, and has no idea why that is happening.

I have checked settings to make sure it doesnt save anything to the desktop, the folder is set to save inside appdata/roaming

We have tried updating the program with no luck so far, just updated it again today. Costumer is nervous towards deleting the program and setting up his email again, I have told him that his emails and folders wont be effected. But still doesnt want us to do it.

So unless you can give confirmation that nothing will happen to his files and folders he wont let us reinstall the program.

Can you let us know if its a known bug or better yet, give us a solution, we would both be very grateful.

Kind regards

Bonjour, depuis des années ,je consulte ma boite mail : [edited]@free ,en clickant sur le symbole thunderbird dans ma barre de commande ! ces derniers jours je n'ai plus d'accés , en clickant je n'ai plus de réponse! Suite a cela j'ai redemandais à réinstaller Thunderbird dans mon ordi ,mais je n'y arrive pas ???

I have no idea what to do now that I have downloaded Thunderbird email on my Surface 4. I can't find any directions anywhere on how to get started with it.! Outlook, while not secure, was certainly easy to set up and use.

Firstly, both laptops are working well. While one is still behaving quite normal, I am unable to install Mozilla Thunderbird on the other after having done a reset .. The "HUB" will NOT except my personal details i.e. email address & PW which I've used for years. I'll leave it at that for now ..

I want to install Mozila Email on my Windows 10 Laptop and want not to use the default version 150 but version 142. The support still downloads version 150 when I choose verso 142. What can I do to correct this?

Comcast/xfinity has replaced its e-mail with Yahoo mail I want to install and use Thunderbird instead I Have followed all the installation prodeedures but T bird will not connect/run. Has comcast made it impossible to use Thunderbird and if not, hoe do I get it to run

I have been using Thunderbird Portable e-mail under Windows 10 for a number of years . About 4 months ago I installed on a Windows 11 computer - it worked for a few weeks, then one morning I received a message stating it will not run because a 16 bit program will not run in a 64 bit environment.

I am hoping that there will be a 64 bit portable version for Windows, based on my previous usage.

Would I be able to install the normal version on an external portable drive? When I go visiting, it is convenient to be able to take just the external drive. Currently, the external drive is a high capacity USB drive. However, if this is not possible, is the current Windows 11 version ready to go?

My current e-mail system is a long time DOS system via my ISP. That e-mail address is my only e-mail address, used for over twenty years. I would prefer not to have to change it.

What I have been doing is to use Thunderbird Portable to download my e-mails into Thunderbird on my computer, which allows me to store my e-mails offline for a financial year.

I am hoping to find an option to continue this by June 30.

Regards and Thank you, Kevin Cassidy [edited email from public community support forum]
