I have had the same signature attachment for several years on my Thunderbird email, but for the last week, new messages and replies are no longer bringing in the signature image for my emails. Additionally, if I go into settings and try to choose the signature as a reset mechanism, the 'choose' button does not react at all....does not go to file selection window where I can reselect the signature again. I can create a v-card, but it is also not attaching. The attached image appears as if everthing is set-up correctly, but the feature is not functioning. Please advise.

Bonjour, A la maison, je suis sur iMac M4, pour le sérieux et sous Linux Mint pour respirer dans le monde du libre. Sur Mon iMac,j'ai bien la dernière version d'installée: 153.04.0 esr

Sur ma messagerie Thunderbird, je n'arrive par à joindre un fichier (PJ) dans un message départ. - Quand je clic sur "Ajouter une pièce jointe", aucune fenêtre ne s'ouvre (Finder)

Quand je suis sous Linux, tout fonctionne bien.

Cordialement

After new installation I want to use my profile of the former installation. In principle I followed the procedure of the article "An einem anderen Ort wiederherstellen". After that when starting thunderbird it always asks me to create a new account.

Does anyone know what is missing?

Thunderbird is difficult to maintain consistent operation.

Periodically, the font color changes without warning, and your settings options is very limited and or 'WELL' hidden.

Making it virtually impossible to find out how to change various screen graphical settings, such as 'font color' or 'font size', etc.

This is not the first time my font color has changed, and I can't find out how to reset the font color in the Calendar editor for any particular calendar event, either creating and or editing a change to the calendar event.

So please, provide me with an instruction on how to change the font color in ANY calendar event, via your Calendar editor.

My Calendar editor in the comments block is set currently with a black background and 'black' font color. So I cannot read a darn thing in the comments block. FYI, when currently using the mail editor, I have a white background with black text, working OK. But NOT the calendar editor.

After all these years, you would of thought Mozilla, either Firefox or Tbird, would have provided a good help dialogue on screen to inform users on how to do things like this. You either have done so and kept it a trade secret, and or have NOT improved upon your terrible user guide instructions.

Thanks in advance.

This morning, my email Inbox is empty. I use Thunderbird for four email accounts, and three of them are fine, but the fourth one has an empty Inbox this morning. I didn't (intentionally, anyway) move the emails anywhere, and they do appear to be in the All Mail folder, so I didn't lose them entirely. But I keep my emails mostly in my Inbox and they aren't there anymore.

Any ideas what happened to make them disappear and how I can get them back to the Inbox?

Thanks!

I can no longer attach messages to an email I am sending via the attach button. I can drag and drop but that is clunky. Using version 157.0.1 (64-bit) on PC running windows 11

Please provide contact information (phone number).. I need to talk to a real, live human being. Your articles and references are not understandable to me. Please help me restore Thunderbird e-mail function and service. Thanks you.

Using Thunderbird 115.18.0esr Supernova 64-bit on Mac laptop OS 10.13.6. Worked fine for years, with ongoing Thunderbird updates, even though Mac OS is 32-bit. Suddenly, after 10/6/26 can't retrieve emails although I can see them on the ATT Yahoo server website. Can still send emails with Thunderbird. Inbound server settings are: POP server inbound.att.net, Port 995, SSL/TLS, Normal Password (I long ago created a Secure Mail Key, and even tried creating a new one). But inbound server name doesn't show in Saved Passwords (only outbound server with Secure Mail Key as password)? I have tried everything suggested, repaired my inbox folder, updated Thunderbird files, etc. in Profile as recommended. But still no prompt for password when attempting to get messages. Just shows "Done" at bottom left with no new messages received. But new messages are seen on server website. So it appears that Thunderbird isn't able to connect to the ATT Yahoo server to get emails. Why? And what else can I do? I love Thunderbird and want to continue using it.

I've been using Thunderbird for several years, but I still don't quite understand how it works. A week ago or so I was unable to add attachments to email and it was suggested to me that I should reinstall Thunderbird, and the claim was made that I would lose neither my email nor the settings. So I did reinstall Thunderbird and found out that all my Local Folders were gone and that I had to configure all my email accounts from scratch, which I did.

Since I regularly back up my home directory using the Ubuntu Backups app, I thought I could restore my Thunderbird data from a recent back-up. Following some advice I'd found on the internet, I restored the ~/.thunderbird directory from a recent backup and saved it at the desktop. Then I replaced the current ~/.thunderbird directory with the one restored from the back-up (cp -r ~/Desktop/.thunderbird/ ~/). When I re-launched Thunderbird, I noticed the following: (1) All the Local Folders that I had created in 2024 and before were restored, but not the more recent ones (i.e, the ones created in 2025 and 2026). (2) The restored Local Folders did not contain any emails dated after early September 2024, which I think is the time when I upgraded Ubuntu 22.04 to Ubuntu 24.04. Looking at the restored profile directory (~/Desktop/.thunderbird/cvb2eouj.default-release/Mail/Local\ Folders), I see that the missing Local Folders are not there, which makes me believe that the problem happened at the stage of making a back-up of my home directory rather than during the restoration process. Is it possible that the location of Thunderbird data moved from ~/.thunderbird elsewhere at the time when the transition to the snap version of Thunderbird took place in Ubuntu 24.04? If so, what is the new location? Knowing the names of some of the missing Local Folders, I have tried to search for them in my home directory, but found none (find /home/<user name>/ -name <name of a missing Local Folder> -print).

I also wonder whether I could use backup data that were created at the time when I uninstalled whatever version of Thunderbird I had prior to clean installation of Thunderbird 157.0. I recall that uninstallation took a lot of time because a back-up was being created (sudo snap remove thunderbird). I have no idea where that back-up was saved, however.

So now I have Thunderbird 157.0 installed and configured on Ubuntu 26.04, I can send and receive e-mail in all my accounts, but Local Folders created after September 2024 are missing, and the ones that exist contain only relatively old emails (older than September 2024).

I would appreciate help and ideas on how to restore the missing Local Directories and emails from home directory backups.

I have a very long list of filters and would like to have the list alphabetized. Is there a way other than "move to [I don't know--bottom? top?]. An alphabetized list would certainly help. Thanks,

Since updating to TB 153esr from the previous esr, I occasionally get a server authentication error with imap.gmail.com. Most often they happen when first starting up, but occasionally seem to happen at other times. They seem to be transient as gmail works fine otherwise.

Just wondering if this is a known bug?

Hello! I'm having a problem where a specific tag keeps un-applying itself. I have a number of filters that look for specific words in emails, and tag them accordingly -- all of my other filters are working just fine, but one specific one has decided to stop working. It has exactly the same settings as the other ones, and when I manually run the filter, it correctly applies the right tag.

But, minutes later, the tag will un-apply itself, and I cannot figure out why. For some reason, an older message is staying correctly tagged with that filter, but newer ones un-apply the tag. This same filter and tag used to work just fine. Other tags on emails from the same source work fine, too.

I’m looking for card body previews in the message list/card view, similar to seeing a short preview of the email body under the subject/sender. Is this feature currently available anywhere in Thunderbird?

If not, is it planned, and is there any estimated version or timeline for when it may be added?
