I copy/paste emails a lot for my job, which needs to include from, sent, to, cc, bcc, and subject:

From: Sender <sender@email.com>; Sent: Wednesday, January 21, 2026 at 11:27 AM EST To: John Doe <johndoe@email.com>; Cc: Jane Doe <janedoe@email.com>; Bcc: Subject: Email Subject

Currently, I am using the plugin ReplyWithHeader, which will produce this style of header on reply/forward, but is there a way to display this in the email body on view, without me having to reply/forward to produce the headers in the email body?

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 :-)

When I open an email that contains a thread, each response (or reply) shows up in its own window. This results in LOTS of email windows on the screen, and I have to fish around to find the one I want to see. Then I have to close all of them one at a time. How can I change this so the email thread is in one continuous window?

[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.

I am on 140.7.1esr (64-bit). My sub-folders under Inbox is not sorted alphabetically. I do not see any option to re-sort at the pop-up menu after I right-click at the account name. Does this mean the version I am on does not have this feature?

When I receive a Popup that an email has been downloaded, and I click on Delete, this action takes me to the email app. I should just delete the email and leave me where I am on my desk top, not take me to Thunderbird.

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?

'Hey Ed .. need your advice again'

Open your TB profile:

- TB menu > Help > Troubleshooting Information

- click the Application Basics > Profile Folder 'Open Folder' button

- close TB and rename the folderCache.json file to folderCache.jsox

Restart TB and the list should be gone. Note this will also remove the list from the R. click > Copy To list.

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

These are the 3 files in the profile folder. I'm confused ..which file do I rename? TB is closed This file folderCache.jsox .json - create date 01/13/2026 was created when I used above procedure on 1/13/2026...

I already have a folderCache.jsox file ... renaming it leads to file being unusable. '

folderCache.jsox - create date 12/21/2025

folderCache.jsox .json - create date 01/13/2026

folderCache.json - create date 02/02/2026

Thanks,Mike

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.

I use a 32" monitor. In Thunderbird, I want to create some Message Filters. I bring up the Message Filter window and enter a filter. When I go to click the OK button to save the filter, I cannot see the button on the screen so I try to scroll the window via the scroll bars to find it but it won't scroll. I next try to shrink the window by using the CTRL key plus the mouse scroll wheel but nothing happens.

I cannot see any way to create and save Message Filters in Thunderbird unless the window can be reduced. Why does Thunderbird NOT use Windows facilities? I can generally shrink or expand a window by the Windows facility of CTRL + scroll wheel, but not so in Thunderbird.

I need some direction, please.

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.

I’m running Thunderbird 147.0.1 (64-bit) on both my desktop and laptop, both using Windows 11 Version 25H2 (Build 26200.7705). I’m trying to highlight sent (outgoing) messages where the correspondent and recipient are different (i.e., not sending to myself). When this condition is met, I want the subject line to appear green. My logic is: • Match outgoing mail where the correspondent column contains one of my addresses • Exclude rows where the recipient column also contains one of my addresses • Apply formatting only to the subject column tr:has(

   td.correspondentcol-column[title*="@pm.me"],
   td.correspondentcol-column[title*="@protonmail.com"],
   td.correspondentcol-column[title*="@passinbox.com"]

):not(

   :has(td.recipientcol-column[title*="@pm.me"]),
   :has(td.recipientcol-column[title*="@protonmail.com"]),
   :has(td.recipientcol-column[title*="@passinbox.com"])

) td.subjectcol-column {

 color: var(--tb-green) !important;
 font-weight: 600 !important;
 background-color: #e8f5e9 !important;

} Same Thunderbird version, same Windows build, same CSS file, same mail account structure. Is there something on the desktop system that could prevent this from working? For example: • about:config setting related to CSS • Layout or column differences affecting selectors • Rendering engine differences between installations • UI density / table layout mode differences My expectation is that this logic should behave identically on both systems, so I suspect a configuration or UI state difference. Any guidance would be appreciated.
