I made a mistake. I had 128 and went up to 140. It pretty much looks the same, but a big difference is an extension I always use says it will not work with 140. I don't care how good 140 might be; if I can't use my app, QUICKTEXT, then I don't need this. How do I go back to 128 or to a version that works with my extension?

I was following instructions for the problem of some task bar icons showing as grey boxes. Still have that problem plus added the problem that thunderbird launches with the setup accounts dialogue page. The 'help>troubleshooting information>profile file location' reveals the correct profiles that have been updated to the hour before I caused the problem. I have saved the '...roaming/thunderbird folder to an external SSD, and made a new new thunderbird installation following the instructions for moving files to a new computer. Problem persists. Thunderbird will not 'see' the profiles therefore I cannot see my emails.

Trying to set up existing email address. When I type in info, it says "Configuration found ..." When I hit done, I get "unable to log in at server. Probably wrong configuration, username, or password."

I have a Mac and have been using Apple Mail. I'm not sure what to do next. I was able to open my Apple account, but that password does not appear to work.

Any suggestions as to what I'm doing wrong and how to fix it?

Thanks

This is minor, however, some addons that I need currently only work up to version 138. The version found at Index of /pub/thunderbird/releases/138.0.2/win64/ is actually version 139.x. I was able to download 138.0.1 at Index of /pub/thunderbird/releases/138.0.1/win64/

I am currently running Thunderbird version 128.11.0esr on Windows 11 on a Dell desktop computer.

I have been running Thunderbird for years. But back in February 2025 my previous Dell desktop died, so had to purchase a new Dell desktop running Windows 11. Then I downloaded Thunderbird and installed it on the new desktop then copied over the profiles that fortunately had been backed up just a week prior. It has been working fine. (When I installed the Thunderbird on the new computer I did not realize there was a difference between ESR (Extended Support Release) channel and Release channel; I just downloaded and installed what I came upon.)

However, around 5/28/25 got a pop-up message that stated something to the effect it is recommended I upgrade to Thunderbird Release.

Should I download and install a new Thunderbird from the Release channel? Will the existing profiles work with the Release channel Thunderbird? Thank you for your help.

I am trying to upgrade from ESR to Release. I saved my profile successfully, went to the install page and clicked Download. Got a request to donate, which I did. Then I got a page saying Thank you, Finish installing and enjoy Thunderbird. But there is no way to finish installing and I never got a download file. I've tried multiple times, nothing happens. Help!

I just purchased a new laptop and am trying to get Thunderbird up and running. I have an outlook email account and use it's calendar. On my previous laptop (manjaro linux) I ran Thunderbird version 138.0 which allowed me to install TBSync and customize via the chrome file. It worked great at bringing the calendar over to Thunderbird. Now, on my new laptop (also Manjaro Linux) the package manager is only presenting version 139+ to install but TBSync does not work on this version of Thunderbird and I can't figure out how to install Thunderbird version 138 on the new laptop.

So, I need help either syncing my calendar in thunderbird version 139 to my outlook account or on how to install thunderbird version 138 so I can add TBSync. I've downloaded the file for version 138 but don't know how to install it. This shouldn't be so difficult.

Your assistance is greatly appreciated.

I am trying to upgrade from 128 esr version to the new 139 version. I tried several ways to transfer data from the old version to the new version - I tried to export and import a the Thunderbird zip file. I also tried to open profile manager and creating a new profile that refers to a copy from my old version. Nothing has worked. In the old Thunderbird 128 version, if I select Help and Troubleshooting Information and then Open Folder next to the Profile Folder I get an error in Thunderbird that it can’t find my profile. I get the same error message when I go to Tools, export and select "open profile folder." This in spite of the fact that the old version continues to correctly display my contacts, tasks and events

After several hours of this, I finally decided to download version 139 using the standard Mozilla set up even though my Thunderbird 128 version is located someplace else. So, at this time I have two working versions of thunderbird on my computer – the old 128 version with all my data and the new 139 version with no data.

I think I need help figuring out which Profile has my contact, calendar and task data. Then I need help getting it to the new version.

Thanks

Luke

I got this while updating. Computer was off for 11 days (i hospital). Now I can't load my email. There are several PDF's of medical test requests and reports urgently needed to print. I can see my mail waiting on the server using my phone, but my desktop (Thunderbird) is the only one that will allow me to print.

I have been very sick and got this email the other day about Pocket shutting down - I am not sure what all that means for me.

I am using Thunderbird for several MSN based accounts - do I need to move them? I also used it for one local account that is a google account it appears but had to move it elsewhere. Obviously that isn't going to move since it is dead for all practical purposes. But do I have to move my MSN accounts (old hotmails and lives for example) or can I continue to use Thunderbird for them.

Just to know how sick I have been finally got a diagnosis. It took me months to get windows update to work finally - just didn't have the energy to try to get it working until last night and then I used a MSN employee. I just can't do much myself anymore.

Ran your update today. Thunderbird has completely disappeared. The shortcuts no longer work. When doing a search in Explorer I find a Thunderbird folder in C:\Programs. There is no file named Thunderbird there and the three exe files either do noting or complain that something is missing.

I am now missing literally thousands of emails.

I have received two emails from Spark wanting me to switch my email to their program. I hope you can fix this screw up because if you do not I will switch my email to Spark and make my default browser Chrome. I do not support companies that do what you just did. Completely unacceptable.

Windows 10 Home No info on Thunderbird because you messed up and I can't run it.

I recently changed onto the new release channel by installing version 136. I now find that this new release channel appears to have installed version 138, but it is reported as a beta version. I do not want to use beta versions, as I am having a lot of problems with it, so how can I return to a stable release?

This has been re-posted. In error my first post said ‘Firefox’ NOT ‘Thunderbird’.

Hi all. I recently had a terminal problem on my Win 10 computer so have bought a new Win 11 machine. I ran Thunderbird mail on the old Win 10, had 5 email accounts, had about 12 local folders and had my Profile stored in a folder on the desktop. The folder was moved there some years ago but don 't remember how I did it. I moved it there because this folder gets backed up every night.

So, I have managed to remove the HDD from my old machine and have located the 'old' profile folder. I now need to re-install Thunderbird on the new machine and match it up to my old profile folder (I think...)

Any advice on how to do that?

I am running Thunderbird vers 127 (I think) on Win 10. When I try to start it all I get is the error -

"A newer version of Thunderbird may have made changes to your profile which are no longer compatible with this older version. Use this profile only with that newer version, or create a new profile for this installation of Thunderbird. Creating a new profile requires setting up your accounts, calendars and add-ons again..".

How do I get back to my profile? All was fine until May 7th when I went on hols but but this happened when I tried to restart on 19th May (so don't think it has updated to vers 128)

Any help much appreciated as this is a complicated profile and would take an age to re-build. (I have got a coy of the relevant profile as a backup)

Hello I'm using TB 128 esr / flatpak on Ubuntu 25.04. I'm satisfied, but I want to install Thunderbird in parallel before switching to this version. https://support.mozilla.org/fr/kb/installer-thunderbird-sous-linux#w_changing-channels I read and managed to install TB "monthly beta" by extracting the tar file. It wasn't possible to retrieve the profile via the zip file because it's 2.4 GB. It seems to work, even though it uses quite a bit of CPU power, ~20%!

1/ Anyway, my main interest would be to have a usage similar to Firefox standalone, which I can use from my computer to my laptop :-) with the same profile stored on an SSD data drive. I don't want to install the profile on my computer or laptop system drives!

2/ How do I launch this version at startup?
