I get an error message when I try to update (see screen shot below). Thunderbird is on a Windows 11 Pro PC with the latest Windows updates. This has been happening for a couple of weeks now.

Thanks in advance for your assistance.

Signed on to Thunderbird a couple of days ago to see a message about a new release. Seeing no way around it, I went for the update. Thunderbird now opens to a screen asking for an account setup. Name, email, and password--which I assume is the main email server (AOL in this case). I fill this in, click on test, and Thunderbird comes back with an available POP3 configuration it found, which is not the one I have been using for several years. I try it out, Thunderbird tests the password and finds something in the password or configuration that doesn't work. I try a manual configuration the the correct pop3 and smtp addresses and get the same result. I am at a complete loss at this time. This is all I get when I try to open Thunderbird--none of the usual email boxes, calendar, contact screens at all. I cancel the setup and get an option to continue and potentially not have access to some features, or exit. I click on exit and a new screen opens with file tabs for email, calendar, address book, and tasks. Looks nice, but there is no data brought forward on any of these tabs, and email looks like it has not been set up (no surprise--no inbox or preview box).

Any ideas on how to complete his setup and bring the data in, or on how to go back to the previous release and uninstall the new version?

It appears that any ESR version will auto upgrade to the Release version right after you close the program and shut your machine down. When you go back online, surprise!, you now have 144.0.1 installed with HALF your folders missing.

Yesterday, I thought I had my original problem with TB fixed by installing v140.5.0. Well, things just got worse.

While trouble shooting it today, it AUTO UPGRADED to v144.0.1.

Good day, After upgrading Thunderbird to 143.0.1, I noticed that a large part of one of my local folders is missing. Searching the internet regarding this problem, I found that this issue happened last year and at other occasions. Why hasn't this problem been solved yet at it is a pain to locate and find the missing data ourself. Any suggestions to avoid this problem in the future

How can you remove the regular reminder to update firefox to the newest version on macos that occurs when you tick "Check for updates but let you choose to install them"?

I have automatic updates disabled, for the last month or longer I have refused to update Firefox and kept dismissing the notice when I start up my Firefox. Yesterday when I opened Firefox it just updated itself automatically and without even asking if I want to download the update. I tried to find a way to contact support but all I can find is posting a question on here, so hopefully someone can help me with this question: Why did Firefox ignore my update settings and download and install an update I have been denying for weeks now, and how can I prevent it from happening again?

Greetings,

I recently updated to Thunderbird 140. After the update, I am unable to open .eml files by double clicking on them. I receive message window (attached image). If I do File->Open->SavedMessage I can successfully open the file. Please advise how I can get Thunderbird to open .eml files regardless of the instance of Thunderbird that originally created the file.

Hi, how do I get rid of

"Error: Platform version '143.0.1' is not compatible with minVersion >=141.0 maxVersion <= 141.0 Maybe try to reinstall Thunderbird?"

It's not very practible to do a new copy everytime a Thunderbird Update has to be made because I mainly store my emails in a local copy (respectively a lot of copies already).

could you please help me?

Thx & BR Eva

Hi,

I installed Thunderbird 140.2.1 on WIndows 11 v25H2 with winget but it autoupdated to release version 144. I uninstalled release version 144, re-installed esr version and disabled Updates in Settings, but it auto-updated to release version. So I uninstalled one more time release version, installed esr 144, disabled Updates in Settings and I set up the registry key DisableAppUpdate at 1 but Thunderbird auto-updated again to release version 144.0

Please, can you tell me what can I do to prevent Thunderbird esr auto-updating to release version ?

Thanks.

I have a Thunderbird 32 bit version 128 running on Windows 10 Pro. 16 GB memory with 512 GB storage

I first like to know if I upgrade to 64 bit version of Thunderbird. Beside doing a backup of the 32 bit version what be the best way to backup. I planning on using onedrive to backup the data. Any suggestions there is there extension anyone can recommend?

Can I upgrade to 64 bit version without having to do anything?

The second thing please reference the image attached to this thread. As you noticed there a lot of folders in INBOX and in Drafts. I tried moving them but seems they are not relocating. I even tried copying to them to another folder.

Should I try upgrading thunderbird to 32 bit first? There so many folders and subfolders that I don't think thunderbird can handle moving that much data.

The person who setup this application does not have any computer background at all.

I appreciate anyone who can assist with this issue.
