Trying to report a bug in Thunderbird:

Subject: Missing message preview/snippet in Thunderbird 115 (Supernova)

Hello Thunderbird team,

I’ve been using Thunderbird 115 (Supernova) and noticed that the message list no longer shows a preview/snippet of the email body. In earlier versions, this was available as the “Message Preview Text” column, but in Supernova neither Table View nor Cards View currently display snippets.

For many users (myself included), having a one‑line preview of the message body is an important part of quickly scanning the inbox — it’s a feature Outlook and other clients provide, and it makes Thunderbird much more efficient to use.

Could you confirm if this feature is planned to return in a future release? If so, is there an estimated timeline? Even a rough idea would help us understand whether to wait for it or look for alternatives.

Thank you for all your work on Thunderbird — it’s a great project, and I appreciate the effort that goes into keeping it modern and usable.

There surely must be a way to permanently disable the nag for "Alternate text" when editing an image in an email? I don't want it, need it, use it... There use to be an extension for it, but that is obsolete by now. Can it be done in the Config editor?

In my Thunderbird, I accidentally deleted the Menu Bar from the new Draft box e.g. including Reply, Delete, Print, Save etc, and I can't link my draft with my Contacts to enter the email address of the recipient.

Please return my Computer to using Firefox default as my browser as it was 2/01 /2026.Ive tried several times to do this w/o success . I was using windows 11 and have been trying to get rid of MS365 which I never used but have been charged for a solution , but have been blocked and refused cancellation after they asked me to change my email address and PW . Insanely confusing !

Update: Apologies, seems it was my mistake. While setting up the signature in the first place I *did* pick up a named anchor from a template <a name="_MailAutoSig">. It was buried in the generated HTML, and I have now found and removed it. Problem, such as it was, now solved.

Is there any way either to remove the yellow anchor symbol which Thunderbird inserts in front of my signature, or to tell the client not to display the symbol? I didn't put one in the HTML signature that I use. There's no "remove named anchor" command. It isn't related to the double -- marker, which I've already removed using config. I have no use for anchors, which for me are simply a visual distraction.

Thunderbird is so good in many ways (calendar synch is great - one of my major bugbears with Outlook - also recipient privacy when sending out group invitations) and it can be quite frustrating in some others (e.g. unwanted features that I've had to dig around in config in order to turn off)

Thanks everyone :-)

[DESKTOP VERSION] The font display size in the email composition window is at least 2 'clicks' smaller that what is actually displayed in the received email. When writing an email I need to do a double Ctrl+"+" in order for the text to be easy to ready. When I read the sent email (sometimes I need to send emails between accounts - I have 14 between my business domain and my personal domain), the text that I entered is the proper size. I can easily see this because of the graphic image in my signature, which is the same size in the composition window as it is in the received email. See attached composite graphic.

Hello and thanks-in-advance: it would be nice if we could re-order the email accounts listed in the left column, so for our particular workflow, we could process emails from accounts in an order we prioritize. Can this be done?

Bonjour M. David et grand merci pour votre soutien. Je suis désolé de vous solliciter autant ! Pardonnez-moi mais je commence à être vieux (83 ans et demi …). Je commence mieux à comprendre votre proposition pour la commande « insérer » (on verra l’autre problème plus tard). J’ai cliqué sur la commande « nouveau message » en même temps que sur la commande « MAJ » (je pense que c’est celle qui permet de saisir une majuscule) mais cela ne m’a rien donné. En revanche, j’ai cliqué sur « paramètres des comptes » et j’ai cliqué sur « HTML » (voir image ci-jointe appelée « HTML »), mais cela ne change rien car je ne vois toujours pas comment ajouter la commande « insérer » dans la barre d’outils. D’ailleurs je n’ai pas vu la mention « composition et adressage ». Par contre j’ai essayé d’ajouter d’autres commandes dans la barre d’outils en cliquant sur « affichage » « barre d’outils » « personnaliser », mais je n’ai pas vu la commande « insérer » (voir image ci-jointe « barre outils »). Si vous avez le temps de continuer à m’aider, je vous en remercie bien sincèrement.

Hello Mr. David and many thanks for your support. I'm sorry to ask you so much! Forgive me but I'm starting to get old (83 and a half years old...). I'm starting to better understand your proposal for the "insert" command (we'll see the other problem later). I clicked on the “new message” command at the same time as the “SHIFT” command (I think it’s the one that allows you to enter a capital letter) but that didn’t give me anything. However, I clicked on “account settings” and I clicked on “HTML” (see attached image called “HTML”), but that doesn’t change anything because I still don’t see how to add the “insert” command to the toolbar. Besides, I didn’t see the mention “composition and addressing”. On the other hand, I tried to add other commands to the toolbar by clicking on “display” “toolbar” “customize”, but I did not see the “insert” command (see attached image “toolbar”). If you have the time to continue to help me, I sincerely thank you.

I have uploaded an image of my view of the email client. As you can see, there are two columns under the red arrows. I have made them appear through a menu accessible by three dots. Somehow, I have lost that menu but touching the wrong choice and I would like to be able to access it again so that I can remove the two colums indicating the number of emails and their weight. Can you help me to retrieve that menu?

When using Thunderbird 140 I am able to setup the background color of the message pane for individual messages. However when the messages are threaded, the message pane shows a preview of all of the threaded messages together in the message pane with a different background color than individual messages.

My previous computer crashed and got a new one (Win 11 of course - new for me).

I downloaded Thunderbird. With the help of an Earthlink (my email) tech, all but one of my emails (gmail) were entered. Then I downloaded and began reading them.

The first thing I noticed was the Next and Previous buttons are missing (or placed where I don't see them).

The second thing I noticed is that when I click on one email to read, all the emails in the respective Inbox also open. This is very annoying.

I also hope someone can tell me the info I need to add a gmail account. (I rarely use it, but there two websites which require a gmail email to log on.)

And I had made a T-bird "backup" but haven't used it yet. I'd like to IF I can locate it.

P.S. Is it possible to shut off the AI "help" while writing this. I find it annoying, slows me down.

Want to clear the 'RIGHT CLICK MOVE EMAIL TO FOLDER LIST ' THAT ACCUMULATES OVER TIME . lIST GETS TOO LONG. Searched thoroughly for an answer but found none.

 Please respond if you know how to clear this list. 

Merry Xmas Mike

It has been several months since Thunderbird has always resulted in a double space when the ENTER key is pressed while composing an email. I have tried all the suggestions offered on this forum. None has been successful. Windows 11 Pro, with all current updates. The app data files are in my Documents folder. Does anyone have a solution? Am I the only one having this problem?

I have been a Thunderbird fan for many years. This is the first time I feel it is time to look for a new email application program.

Is there any way I can prevent Mozilla from installing/enabling more AI features on my Firefox browser in the future?

I do not want AI running on my machine. I do not want AI integration in my browser. I understand I will still run into AI in the wilds of the internet, but I especially do not want these features enabled ON MY OWN MACHINE in an update without me specifically opting into them. Installing and enabling this without user opt-in communicates clear disrespect to the users.

I did a cursory search here for similar questions and Mozilla staff appear to be stating there will be no AI in Firefox unless the user specifically enables it, and it is as simple as disabling them via settings if "accidentally" enabled. This was not my experience, and it is alarming to see false information provided to users .

I have found other sources indicating the following must be set to false in about:config in order to disable browser-side AI/AI integration: browser.ml.chat.enabled browser.ml.chat.page.footerBadge browser.ml.chat.page.menuBadge browser.ml.chat.shortcuts browser.ml.chat.shortcuts.custom browser.ml.chat.sidebar browser.ml.checkForMemory browser.ml.enable browser.ml.linkPreview.shift

Is that all of them, will these disable ALL of the AI in Firefox?

Are there any other settings I need to set to false to ensure no AI is either running on my machine or the browser is not integrating AI functionality from third parties?

Is there any way to ensure Mozilla doesn't force AI features to be enabled without my say-so (again)?

Are there any privacy-minded browsers comparable to Firefox that DO respect their users with regards to forcing AI on them? It may be time to jump ship.

I have set all Notifications on (there seems to be a dozen on/off switches) but new emails do not trigger a marker on the Thunderbird logo or any other form of notification I have to open Thunderbird just to get new messages to download Is there a setting I need to change?

Bonjour à tous, Je cherche comment afficher images distantes par défaut. Jusque là, elles sont cachées et un message s'ajoute : les visualisation des mails ouverts est inutilement compliquée (à mon sens, le principe de sécurité, annoncé à chaque fois à ce sujet, n'est pas adapté.). Merci de m'aider à grive fer le moyen de mettre automatique des "images distantes" par défaut 😊. Bonne journée !

After installing thunderbird, It takes me hours to figure out that my fonts are too small because of one value in Settings > General > Language & Fonts > Fonts > Advanced > Fonts for Other writing systems gives a too small number.

It seems insane and I don't think users can easily get there. Maybe some users want to set different fonts for different languages and the "Fonts for ..." is for them. However, for most users who just want to change their font size, I don't think it's a good experience to going so deep and find an option in the loooong "Fonts for ..." list.

So please give users a simple option where I can just set my font size without such pain.

I know there's a font size option in TB menu but it doesn't work as expected. In my case, the font size shown in TB menu is 16 while the font size of my plain text emails is 12. And 1. email font sizes will change to TB menu size as long as TB menu font size is not 16. For example, when changing TB menu font size 15 -> 16 -> 17, email text just suddenly goes from 15 to as small as 12, and then from 12 to 17. 2. email font size seems changing with the TB menu font size. However, email text font size will go back to what it was when open another email.
