Thunderbird Community Forum

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!

Thunderbird 138/139, Windows 11 Pro 23H2. While composing a message, after a few lines the app freezes. Both the compose window and the main TB window freeze. Only opening the Windows Task manager allows me to close them. This did not happen with earlier versions.

If I save the message every few seconds while composing I can get most of the message back and continue after restarting TB. This behavior is the same in both the normal and troubleshooting TB modes. I can't even find a crash log to send to Mozilla.

Where shall I look next?

Thank you!

I am using 64bit Windows 11 Home. This happened suddenly without any changes on my part that I know of.

Thunderbird suddenly started freezeing right after startup. The only thing I can do is login with the master password then the regular thunderbird screen opens, but I cannot click on anything. Soon after the screen is greyed out. However I can close the program down with the red "x" in the top right corner. It opens a dialog that gives me the opens to close down or wait to respond. The close option works.

The only hint I can see from the frozen screen is that the local Folder seems to have a problem as a subfolder has now multiple copies of itself. It seems to create a new copy of that subfolder every time I try to start the program.

So far I tried reinstalling/updating TB, as I assumed an update had maybe malfunctioned, (it was stuck on version 128, since I could not open TB for about a week now) but upgrading to to version 138 did not help. I also tried starting TB in troubleshoot mode, which made no difference I also tried starting TB while windows was in safe mode, which made no difference.

I read around but people that have problems with TB freezing seem to not have the freeze happen before they can do anything.

I assume something is wrong in my profile, maybe the local folder? But I have no idea to fix anything, since I cannot do anything at all in TB.

Any help would be appreciated! Thanks!

I cannot download thunderbird. I already donated money and the donate screen keeps blocking my install. I CAN NO LONGER RECEIVE EMAIL SO YOU WILL NEED TO TEXT YOUR REPLY TO 603-339-1725

I tried to use Thunderbird today,.. to find the interface was broken, menus were blank, so no ability to look at anything., and error message inferring there was a menu config issue was all that was shown. I duly removed Thunderbird as a snap install, which took a long time as it seemed to be making a backup to somewhere. I then reinstalled Thunderbird 128.11.0esr (64-bit) on my ubuntu 24.04,.. having setup the isp email credentials,.. all seemed fine,.. I then proceeded to import what I assumed was my old local folders... And this is where things went wrong, as I seem to have lost all my archived 2025 emails,.. I say somewhere,.. as I don't seem to be able to find them, I have used the 'find' command to locate anything with 2025 in the file name,.. but without success. At the moment I have a multi-structured 'local folder' entry, but nothing with 2025 in? I anyone able to shed some light on what I may have done wrong Many tx

I saved all my original Thunderbird software as instructed by Thunderbird support. I have now done a clean install of Windows 11 and want to reinstall Thunderbird using the data from my original Thunderbird program. I need help, preferably some one live and not emails going back and forth that don't work.

When I clicked onto one of my gmail accounts, it did a "somersault", and shut down Thunderbird. Email is: vk4cmr@gmail.com Mark Chad Chatfield That was about 2.5 weeks ago. Tried almost everyday to work this out, Zilch. The email address in fault, is on 3 computers. 2 are still operational, But my Main Use computer will NOT go past the required credential check. Have deleted all reference to that email address and tried reinstalling back into Thunderbird, to NO avail. It still works on the sub-computer systems. I cannot find any relevant help files on yr Knowledge Base remotely connected to this problem. Please advise TIA. Mark

I am so frustrated with Thunderbird I'm about to give up and find another app. I had to reload Windows 11 on my computer and before I started I saved all the Thunderbird info as instructed by support. Now that I am back up and running I'm trying to get Thunderbird back. When I down load a new version of Thunderbird it sees that I did have an account in the past and wants to use that info again. I get to a page where I have to put my full name in, then my email address and then a password. The only password I can find in my password folder(real paper) I can only find a Firefox password. I put that in and continue. It recognizes the password and shows me the info it wants to use for my account. I click on "done" and it starts looking for a password again. After a long search it comes back with a yellow box and says "its unable to log in at server. Probably wrong configuration, user name or password." I've tried changing the Primary password but get no results, not able to. Tried uninstalling and running the version I have stored from before the Windows reinstall and I always end up in the same place......I've been banging my head against the wall on this for several days now and am ready to use Microsofts software instead...... Any ideas before I delete and give up on Thunderbird???

Recently, my antivirus has quarantined a suspect file that was found in a message sent to me. in the folder Cache2/entities, the file shows as: 3A58E20EEF97F19073547FCC8E4E74F870C9FC3D I'd like to find the HTML message it references so that I can take the proper action to remove the issue. How do I do that?

how to re-order the actual email messaging filter entries ? Have a filter setup that currently has several entries for FROM and exact user Ids. Would like to create a new top entry with a SUBJECT CONTAINS entry. Only way I've found is to "+" at the top, but it creates a blank entry below the top entry. so - I dup the top entry as the 2nd entry, and then edit the top entry -

my 32bit Thunderbird has just updated to 139.0 and the message pane has changed an I hate the look/layout . how can I get it back to how it looked before the update easily thanks

EDIT: - I sorted it. The update put it to 'Cards View' - I went into settings and switched it to ' Table View' and its back to normal now - phew!

Every time I open Mozella the above pops up, I can still receive and send emails and every thing seems to work ok, not being computer savvy should I be concerned? Any help and suggestions would be great Many thanks Charmayne

I Use Thunderbird on Windows 11. I changed a retention policy on a Local folder to delete messages older than 60 days. Since then Thunderbird stopped responding and has never worked since. When i open Thunderbird it immedeatley stops responding. It does not show any emails in the inbox and folders will not open. I have unistalled and reinstalled Thunderbird opened and closed in Safe mode but nothing works. Closing Thunderbird task via Task Manager does not help either.
