Thunderbird Community Forum

I have used version 145 of Thunderbird "all my life". Until the other day when I installed version 146. I realize of course that development changes things, but I would like to inform you that a 93-year-old has neither the patience, energy or interest in learning the new Thunderbird. I therefore wish that someone would be so kind and send me the installation file for the previous version. (Unfortunately, my own one is in a computer that I no longer own.) Furthermore, I donated 194 SEK on December 26th when I downloaded the program. (And it wasn't the first time.) In summary: I would like to get the installation file for the previous version (for Win11, 64 bit). Best regards Hans Peter Wiehen

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 ?

Is there anyway of completely installing Thunberbird on a different drive and not have any stuff including symlinks in the users home directory?

Installing Thunderbird on a different drive/location is documented and straight forward but it insists on putting stuff in the users home directory C:\Users\<user>\AppData\ .

The problem can be fixed by using copying everything Thunderbird related in the C:\Users\<user>\AppData\ to the other drive and use symlinks from C:\Users\<user>\AppData\ directory to its new location. Thunderbird seems to be ok with symlinks.

I have just donated as per details below, but I can’t download and install Thunderbird. Could you please assist. Thanks in advance,

Fritz Schurig

what is the exact step-by-step process to download and install Mozilla Thunderbird on a Linux mint computer? I have the download from Thunderbird extracted to a directory one off the root? I am not good with Unix terminology. I do not know what file I have to execute or if at the command line, what code to install the program.

Have deleted install pkg from W10 computer (PC). Figured if all was deleted new install would be easy. But, I keep getting message" Your Thunderbird Profile cannot be loaded. It may be\ missing or inaccessible"

If I have deleted all attempts at installing how can I need the profile? Wouldn't it be created in the new install. What specific files or folders should I be looking for? I have referred to "How do I find my Profile? and associated documents. and uninstalling the Firefox file from the MS apps list doesn't seem to clean this message trigger.

Frustrated after 5 tries...

Hello,

I failed to install Thunderbird 147.0.dmg on my Mac operating under High Sierrra version 10.13.6. I am getting an error message that the file is damaged when I try to execute it.

I am interested to switch to Thunderbird as an alternative to Mail. Would anybody has a solution ? Which older version of Thunderbird would work with my OS ?

Thanks in advance for your help.
