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

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!

The 13x version appears to have introduced a bug.

When pasting links into emails, and then "inserting" the link, if you try to add any advanced options to the link (i.e. target=_blank), it doesn't create the link.

If you simply "insert" the link without setting any advanced options, then the link is created.

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!

This started for me today on Thunderbird for Linux Mint 128.10.2esr.

I have searched this and found others have had this problem off and on since 2019 or before.

I have not found a useful solution.

So, what changed?

Why?

How to return to the previous functionality which was just fine for my needs?

thanks in advance for any help

After calendar notifications popped up and were closed/dismissed, the empty notification window remains open.

It should close when the last open notification is closed.

I tried to delete the cash.sqlite files and a troubleshoot-mode restart but that did not change anything.

WIndows 10, Thunderbird 128.11

I have added a certificate to the Thunderbird Certificate Manager (localcert.png), with the info as shown in certdetails.png. However, Thunderbird is not sending the certificate. I have "When a server requests my personal certificate" set to "Ask me every time". I also tried choosing "Select one automatically" but that did not change the result.

However, my mail server, which uses TLS client certificates as one factor in sender authentication says: May 27 02:00:05 Mercury2 smtpd[9850]: b972fe936721dfe0 smtp disconnected reason="io-error: handshake failed: error:0A0000C7:SSL routines::peer did not return a certificate"

What am I doing wrong in the config that is causing Thunderbird to not send the certificate?

I got a new PC with Windows 11. I installed Thunderbird 136.0.1 , activated the private calendar, and entered events there. For events with a reminder that have a specific duration (e.g., Wednesday from 10 AM to 11 AM), I receive notifications. However, when I create a full-day event and want to be reminded, for example, 1 day before, I don't receive any notification. Additionally, events with a reminder are not shown in bold in the calendar overview (whether they have a specific duration or are all-day events). Can you please help me?

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!

Yesterday and today has just been a nightmare. But I'm slowly getting things back up and connected after Hostway absorbed my hosting company (HostMySite) and migrated everything to their servers, but forgetting to send me the new login info until after they had terminated my old e-mail servers. And then it just got worse.

I am using Thunderbird 102.15.1 64-bit on a M1 mac. Do not tell me to upgrade. I did, once, and revised search functionality literally had me spending 3 days to manually revert my entire database back to work with 102.15.1. New version - bad. No.

The thing I need help with is that, as I reconnect my e-mails to Hostway's servers, I can get e-mails, but the collected Inbox does not show anything new. When I select a specific account within the collected Inbox, it'll have 10 new e-mails, but the collected Inbox- nothing new.

Same with all the collected folders, Drafts, Sent, Junk, trash, etc.

How doI get the collected folders to work again?

In Thunderbird, when I hit "get messages" it replies"Enter your password" Now, without my changing anything, it no longer recognizes the p/w. When I repeat, it replies"....too many commands before authf7mb153666557ooe". I'm using the same configuration i have always used: pop.gmail, SSL/TLS, normal password. I have tried changing this config within the limits of what Thunderbird Account setting offer but to no avail. Also tried on gmail security settings "allow less secure app access" - also no result

Several years ago, I switched over to the beta path of Thunderbird... In doing so, I created a new profile for the beta installation, leaving the old one behind in case I wanted to abandon beta... So I had two profile folders; I *thought* they were this:

current profile: c:\notes\Thunderbird original backup profile: c:\notes\Thunderbird.b115

Now, I've decided that there is no reason to retain the old Thunderbird profile folder, since I'm clearly committed to the beta path... however, I have discovered an anomaly... *both* the old and new profiles are periodically being updated!! Thunderbird.b115 is apparently actually my active profile, but Thunderbird was updated just a few days ago.

When I look at About Profiles, I actually see *three* profile folders listed:

Profile: Gorlash: (default: no) c:\notes\Thunderbird

Profile: Derell Licht beta: (default: no) c:\notes\Thunderbird

Profile: Thunderbird beta (default: no) c:\notes\Thunderbird.beta (note that this folder does not exist)

Profile: Thunderbird b115: (default: yes) c:\notes\Thunderbird.b115

===========================================

Is there something that I could do to consolidate all of this into just one folder? I don't even *know* what those Gorlash and Derell Licht profiles refer to... Yes, those are both usernames that I use online, in various contexts, but as far as I know, I don't use them in Thunderbird...

Q1: Can I just delete those other profiles where default is NO ?? Q2: Why is c:\notes\Thunderbird still getting periodic updates, even though those profiles are not default??

Hello,

I'm running TB128 under Windows 11. I had a boot problem, restored a recent image, and now, when I attempt to launch TB, I get the error below, telling me that a newer version of TB may have made changes to my profile, and that I'm running an incompatible, older version of TB. I've experimented with this situation until my fingers are bleeding, but can't open TB using my newly restored profile.

Any assistance is most appreciated, Lothar

yes, so the title gives the question.

when I start the thunderbird app on windows 10 laptop it starts to fetch 2000+ emails from google. Everytime even after letting it go through the process.

Its super slow and always reports its stuck at 2 out of 2000+ emails. Very strange.

I have let it run for 24 hours+ on one occation to get everything loaded. The loading status bar disappeared but it restarts everytime I open the app again.

Any idea why?

Best regards,

Oskar

This app comes with lots and lots of updates, and every time I have to delete the old start icon on the task bar and re-pin it. Please, fix it so that I never have to do that again. There is no other software at all including Mozilla Firefox that does this to me.

I used to use Mailspring and loved it's combined inbox. Incoming messages for both of my email accounts would show in a combined inbox. I like Thunderbird and wish it had a combined inbox.Do we think it will ever happen?
