My local folders are missing. There is nothing in my profiles to recover from. This is the second time this has happened after a Thunderbird update. Last time the local folder were found in my profile and I was able to restore them, This time there is nothing to restore. Has this happened to other users?

Greetings! I downloaded Thunderbird for my new Win11 desktop, but it gave me an ESR version 128.9.1. It's working fine, but can i just move to the current 137.0.1 version? If so, how do I do that - just grab the current version and install on top of the ESR or should I remove the ESR first? Thanks in advance!

my thunderbird freezes at the point of checking mails. when i try to update it, it opens a new application completely and doesn't update my present one. i also can't find the location of the app or the data. pls help!!!

I am currently running Thunderbird 137.0.2 (64-bit) and I don't get an automatic prompt for updates and haven't been getting them since I updated to Supernova and now Nebula.

I have the settings set to Check for updates, but let me choose whether to install them, which is the setting I have always had and I used to get automatic prompts for updates with a window opening to show the details of the update as I get in Firefox.

Can someone tell me how to get these automatic updates back.

I have attached a screenshot of the update window.

Thanks.

There must have been an update for Thunderbird that screwed up the way I have been using Thunderbird for years now. I had sub folders under inbox. For example, I had an investment newsletter go into a sub folder under inbox labelled "inv". I had a filter set up to move emails that had the name of the newsletter in the title to go to that "inv" folder. In this new version of Thunderbird, those separate sub folders are gone. The filters are still there but the folders are gone. Now all emails just go into the inbox. Is there a way to roll back to a previous version?

TIA Eric

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'm a senior citizen and not very good with computers. Not sure what programs I have other than Windows and Thunderbird for my email. Love the program .. not a minutes problem with it. Received a notice this am about the changes, not sure if that pertains to me. Please enlighten me.

Thunderbird just updated itself to a state where I need to do the setup process manually, which always takes a few hours (with networksolutions as the host). How can I continue to work with the previous version until the bug is fixed or I have time to go through the entire complicated process? Thanks in advance, Knut

Ever since I stupidly let Thunderbird 'update' to 140.5esr 64bit the date format has been wrecked. The program now forces the plain weird US date format of Month-Day-Year. I hoped that this obvious error would be fixed but it's been rather a long time now and the problem - and IT IS A PROBLEM - hasn't been addressed. It looks like Thunderbird is following Firefox in making each version worse. Whilst I switched to Pale Moon long ago there is as yet no fork of Thunderbird. If I were still on Windows for internet use I would just install an older version alas I do not know how to do this on Linux (Q4os Trinity) PLEASE fix this problem. I am far from the first to point this massive mistake out.

I am genuinely grateful to the people who work on these projects but a little more effort on actually being able to use the programs would be a substantial advance.

Could someone please tell me what the latest version of Thunderbird is on the Release Update Channel? I am on version 139.0.2, and when I check for updates in the app, it says that Thunderbird is up-to-date. Is version 140.0 not going to be available on the Release Update Channel?

Hi there,

I'm using Thunderbird on Linux and would like to know if there is a timeline for when the official Flatpak will be switched from ESR to Release Channel. There was a mention in an article on the Thunderbird blog (https://blog.thunderbird.net/2025/03/thunderbird-release-channel-update/) about the release version being available as Flatpak "in the future" but since this was almost three months ago, I was wondering if there is an update regarding this.

I'm aware that I can either install Thunderbird manually or use the beta Flatpak (which already seems to be on release channel) but I would much prefer to use the stable Flatpak.

Thanks!

I would like to know, if there is a reason that the Thunderbird Flatpak still remains on a version published on July 7. Iam switching back to Thunderbird, because of the new Microsoft Exchange Feature.

Is there a Timeline for how the Flatpak updates are delayed or anything that can be done to push the current version into Flathub?

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.

We have Thunderbird 128.13.0esr on 2 Windows 10 PCs, The newest was purchased in late 2021 and now shows the current version as 128.13.0esr (64-bit). The older laptop from mid 2020 shows 128.13.0esr (32-bit). I am planning up updating to Windows 11, reluctantly in the next few months since a few programs like tax software, etc are dropping support for Windows 10. Windows 11 runs some kind of translator for 32 bit applications so ideally Thunderbird should be 64 bit before updating. Not sure how the laptop ended up with 32 bit at the time but I did read where the normal windows download link only offered the 32 bit version though apparently if you had the link to all the versions the 64 bit was available. Is the a way to upgrade to 64 bit or do I need to uninstall the 32 bit app on the laptop after backing up the profiles and then do a clean install of the 64 bit and add the old profile?

Hello, I have Mozilla Thunderbird version 128.12.0esr (32-bit) on a Windows 10 laptop On the Help/About Thunderbird it says update failed. I have clicked on download and have version 139.0.2 in my downloads folder. When I try to install it all goes well until I get a message "Your computer must be restarted to complete a previous uninstall of Thunderbird. Do you want to reboot now?

Yes No " I have rebooted several times now with the same results. What do I need to do to get the update Regards Peter Norris

Hi,

Thunderbird Desktop is now available in the Monthly Release Channel, with version 136.0 released on March 4th, 2025.

More information about this release is not yet updated in the Release Notes.

Currently, only information about the ESR channel is available in the Release Notes.

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.

I didn't know there was a non-ESR version of Thunderbird until I found out by chance a few days ago! Since the latest update to ESR 128.5.2 has crashed 11 times this week, I would like to move to the latest version (64 bit?) non-ESR. There must surely be an official Mozilla step-by-step guide to doing this?
