Forum der Gemeinschaft Thunderbird

Hi, I've been using Thunderbird latest version for a few days. Too much I have a problem that is bothering me. I have 20 accounts and if I choose Unified Folders, on the six of Tunderbird I see only a part of the Accounts and precisely 14. To solve my problem I also used the "Unified Folder Debugging" add-on but it didn't solve the problem. Why do I have this problem? I would like to use Unified Folders but I can't do it because I don't have any Accounts. Thanks for some info.

'Morning, 5-19-26

I'm having an issue that's not major, but irritating. and getting time-consuming.

'Recently left Windows 11 behind (good riddance!) and have gone back to Linux Mint, which is working out well for me. But there's a strange and persistent glitch" when pasting into T-bird from Autokey, which I use daily,

I get typos, dropped spaces, etc, whenever pasting into T-bird BUT INTO NO OTHER PROGRAMS. My workaround has been to paste first into a text editor (which receives the pasted text perfectly formatted), THEN into T-bird from there.

Again, it's not a major, life-threatening issue, but at the end of the day it's a real time-consumer.

I've posted this question on other forums, but no one can give me an answer. Is there a text setting or something n T-bird that I'm missing? A different form of ASCII, etc? Thanks for any suggestions you can think of.

Btw, I've used and loved T-bird for many years, and love it. Best email client I've ever used, and I've been online since the mid-90's (yeah, I'm an antique! ha ha). I try to send a donation once / year. Keep up the good work!

Thanks again, Dave Harnish drs@sosbbs.com

Threading - why does it keep coming back? I have just realised it's back again on my Thunderbird and I never knowingly turned it back on.

Why does Mozilla keep trying to force it on users?

This has been an annoyance for users for several years now and the message has still not got through it would seem.

For an open and user-facing organisation, this is strange behaviour that I just do not comprehend. Include it if you want, but make it optional and easily so.

I know this is only the community forum, not Mozilla, but one would think that a wise organisation would keep an eye on what their customers were saying & feeling.

Hello,

I am on Thunderbird 150.0.2 for Windows.

I am really suffering here. I need to change the font weight of unread messages. In a non-threaded list.

The default weight I get with my preferred font (Trebuchet MS) is not bold. It is BLACK. When I say BLACK, I mean ultra bold, display font, heading weight. Heavier than the boldest font that even exists in the font family. Thunderbird is creating this ultra mega black font by taking the bold font variant and applying a faux bold effect to it. The result is that the text is so heavy that it takes up twice as much horizontal space as the ordinary bold font variant. This becomes a usability issue because it's not possible to see the date, sender, and subject at the same time.

I have struggled and strived with userchrome.css. Spent hours combing through forums here and elsewhere. I've already enabled the mystery setting in the config editor. I put userchrome.css where it is supposed to be.

I saw a blog post from Mozilla that says "userchrome.css is not supported". What is the actual meaning of this? That it has been actively blocked from working anymore, ever, for anyone? Or that users are taking risks if they create userchrome.css? Why can't developers speak plain language? "Not supported" could mean many things.

When I go to the Style Editor, userchrome.css does not exist there. Which leads me to believe that user customizations are absolutely deprecated and we are not permitted to use userchrome.css.

I tried editing some of the rules in the Style Editor, but could not determine any way of actually storing the changes. When I click Save, I get a dialog where I can **EXPORT** the file. But I can't seem to actually save the changes, because CSS files do not appear to exist in the installation directory. It must be compiled into some library.

This is extremely unsatisfying and super frustrating. Just getting straight answers to things is super difficult, nothing stays the same for more than a couple months, and up to date information either does not exist or is not found by any search engine.

So, please help. I just need to change one setting, the font weight of unread messages. Since Thunderbird is allegedly open source, I thought I would have some ability to make such changes. But the Style Editor doesn't seem to actually be an editor, but merely a read-only interface to precompiled rules? If I wanted to change the font weight of unread messages, would I be forced to compile my own version of Thunderbird? I'm not competent to do that, and it would probably either prevent updates, or the updates would break my changes.

Please help, I am super desperate. I need to see the date, sender, and subject all at the same time. That doesn't seem like an unreasonable ask.

I would gladly pay for an email client that gives me control over my data *and* allows me to control the UI, but apparently that doesn't exist.

Whenever I create a new folder in one of my accounts, the new folder appears listed under my Unified Inbox instead of being listed under the account. It is super annoying, and then to correct it, I need to open Unified Inbox properties and uncheck it from the folder list. I only want Inboxes to appear in my Unified Inbox. How do I stop this from happening? Thanks

Hello (this might fit better in "performance & connectivity?): Tbird 140.10.1 & .2 esr. W11p laptop v23. As of tonite (15may26), after update from 140.10.1 to .2, in a message, the "buttons" for a web link no longer appear, in the msg body. Instead the link is shown in full. How can I fix that?

Here's an example (others are longer) from our local rag "Press Democrat."

I also closed & re-opened tbird, did NOT reboot laptop. Problem remains.

Thank you.

I recently updated from a very old version of Thunderbird. The new version no longer shows the little popup messages at the bottom of my screen when automatically checking accounts for mail at the designated interval. As I have numerous email accounts (all set up as POP mail), set to check at different intervals, these popups were useful to me - they also showed when I manually checked an account, or all accounts - this also is not happening anymore. Have they been discontinued, or is it possible I turned them off? I did change some things to suppress nags to update Thunderbird during the time I was using the old version, and unfortunately didn't keep a record of those changes. I'd appreciate knowing which function in about:config controls this feature so I can check to see whether it's set correctly. Thanks!

Français: Bonjour, Presque tout mes icônes dans la barre des tâches, programme ouvert, sont bleu. Comment changer directement la couleur de l'onglet de Thunderbird dans la barre des tâches de Windows. Ce serait bien de pouvoir choisir pour retrouver facilement Thunderbird et lire mon courrier. Christian

English Almost all my icons in the taskbar, for open programs, are blue. How can I directly change the color of the Thunderbird tab in the Windows taskbar? It would be great to be able to choose so I can easily find Thunderbird and read my emails.

How do I change Thunderbird's icon back to the older version? The new version looks a lot like Signal's icon. When I have a taskbar full of icons, I have to look carefully to make sure I'm selecting the correct icon for the app I want to switch to. It's annoying. Thanks

- Linux ver 140.7.1esr (64 bit) my folders are now out of alphabetic order among other things Trash us now under 'T' instead of grouped near the sent folder and my Computer folder has a mind of it's own. It's not under C even after I changed the name. It is just stuck. Wha? tnx

Running Windows 11 and TB 150.0.2. Can't recall exactly what I did, but after clicking on an email all unread emails are no longer in boldface. Any way to restore them? (New emails that come in are in boldface.) Thank you, Joel Hornstein jobby@att.net

I open Thunderbird and see the list of received emails as usual and I have a "Viewing Pane" on the right. In the viweing pane I can see a portion of the email. However, there is a line going through the top portion of the viewing pane email and I cannot see what is under the line. I then fully open the email and the line is still there.

I have tried everything I can think of to fix this to no avail. I have even shut down Viewing Pane in settings and even then when I open an email it is still there.

I am trying to get Thunderbird to function in similar manner of Outlook Classic but the simplest of settings such as viewing pane just won't work. Thunderbird is up to date and Cache cleared. I have attached two photos to show what I am seeing.

Hi

I'm using Thunderbird 140.5 on a desktop Mac running Sequoia 15.7.2

In Local Folders, my subfolders have subfolders. In both levels of subfolders, Thunderbird has spontaneously started disordering both newly created subfolders, and folders which I move from one subfolder to another using right click 'Move To'

Up until ten days ago, all folders whether new or moved, were listed alphabetically. Now, day by day, the disordering is getting worse and as someone with ongoing conversations with hundreds of clients, it is becoming impossible to work when I have to give so much time to slowly scanning through every folder looking for the relevant subfolder.

I don't know why I can't update this version, but I tried installing the newest version available (145) and used the 'reset folder option' which did not work either.

Also, setting up a whole new account instead of upgrading my existing account is a colossal faff and I'd rather not have to!

Aside from manually reordering (also a colossal faff), can anyone suggest something I might be missing in stopping this happening?

Thunderbird says I'm on an esr channel, if that helps

Thanks

For the last 2 months I have been working to configure Thunderbird to fully replace my Gmail UI usage after their recent change to workspace options and using data to train gemini. When you deactivate those gmail features the first thing you lose are tabs for your Inbox, your Updates and your Promotions.

So far I have used tags, ThunderAI, Ollama and a locally hosted LLM to replicate the sorting of my inbox, but now I would like to be able to configure the Thunderbird UI to allow separate tabs in the menu bar for different folders, in this case Inbox, Updates and Promotions. With Inbox still being the gmail hosted main inbox and Updates and Promotions now being local folders stored in my local thunderbird installation.

Can the Thunderbird UI be configured to display folders as tabs as a default setting? I tried the "folder selection" button under customize on the toolbar but that just gives me a drop down, which is not what I want.

I am trying to set up a visualization of the columns of the main interface. Here's what I do:

1. Click on the list icon in the top right corner.
2. Uncheck the columns I want to hide. Specifically, From (CB), Recipient (CB), and Correspondents (CB).
3. Apply the selection to all folders: click on the icon in the top right corner, apply columns to.. > folders and its children... > select account > Confirm

These actions produce immediate results. However, the next day or a few days later, when I reopen the program, the column display changes. Sometimes in the main folder (inbox), sometimes in the subfolders.

Is this a known bug? Is there anything I can do to keep the desired column configuration stable?
