I was confused that apparently "All mail" is now forced to be "Archives", this has happened to both of my email accounts that I use with Thunderbird. Renaming also seems to be blocked. Is there a good reason for this? I find it confusing.

When I select emails to delete (move to Trash) Thunderbird deletes them BUT THEN automatically selects the next email in the list. If I don't notice that, and deselect it, that email gets deleted with the next batch. I've lost several emails this way. So, how do I get Thunderbird to stop selecting the next email after it deletes the ones that I selected. Nothing should be selected after an email is deleted. I don't see anything in the settings menu to do this. If this is a default feature, it's pretty dangerous and should be changed.

After latest update two of my folders no longer have their right names. They where called "DJ LEO" and "Søndre Hamre" as their data files. No they are both callen "Sendt" (norwegian for "Send") and can't be renamed. Content and data files are still right. Why is this hapening. What do I do?

I operate with several to many windows open (and many tabs). Firefox (Mac) used to list the open Windows in the Window menu in the order I originally created/opened each window. A while back, FF started sorting – and re-sorting! – the list of open windows alphabetically according to the Tab that is currently active in each Window. This means that the window appears in different places in the Window menu list according to the name of the Tab. I DO NOT LIKE THAT because the it makes the Window hard to find.

Is there any way to set this to operate the way it used to - keeping the Window list in the order first opened, regardless of which Tab is open?

I use this dark mode theme: Star Trek in Thunderbird but override Thunderbird so that Thunderbird is in light mode and the folder, message list and message panes have a white background with black text. The override uses the Autoconfig method (for Firefox but it was working also in Thunderbird Customize Firefox using AutoConfig . This is my thunderbird.cfg file in Thunderbird's install folder containing:

// IMPORTANT: Start your code on the 2nd line lockPref("browser.theme.content-theme", 2); lockPref("browser.theme.toolbar-theme", 2);

and my autoconfig.js file in Thunderbird's defaults/pref folder containing:

pref("general.config.filename", "thunderbird.cfg"); pref("general.config.obscure_value", 0);

In Thunderbird 145 this worked - all panes had a white background. However, when I updated to Thunderbird 146, the background in the folder, message list and message panes changed to grey with black or white text. With Thunderbird 146, both files are still present and the prefs in about:config are present with the 2 value. The Thunderbird 146 changelog mentions Visual and UX fixes and security fixes.

My Windows 10 colour settings are: default Windows mode = Dark default app mode = Light. These are my preferred settings.

I have changed temporarily to Thunderbird 140.6.0esr and got the white background re-enabled. How do I get the white background and black text back again in Thunderbird 146 please?

I have missing buttons or shortcuts in my Thunderbird. There was a refresh button and a new message button on my tool bar, they have disappeared. Is there a way to get them back? Thank you!

When I receive a newsletter from my club, it doesn't show the pictures. It does describe the picture and warns it might be AI generated. If I reply to the email or forward it, the pictures are displayed. I suspect this might be a settings problem. The original email includes:

[image: A picnic table and benches on a stone surface AI-generated content may be incorrect.] [image: A group of people dancing in a room with lights AI-generated content may be incorrect.]

[image: A person and person standing next to a vase AI-generated content

may be incorrect.] [image: A person sitting at a table with food on it AI-generated content may be incorrect.] [image: A group of people sitting at a table with plates of food AI-generated content may be incorrect.]

[image: A group of people dancing in a room with lights AI-generated content may be incorrect.] [image: A group of women posing for a photo AI-generated content may be incorrect.] [image: A group of people standing in a room with lights AI-generated content may be incorrect.]

Can anyone shed some light on this?

The Delete button (I've just begun using Thunderbird for Android) sends email to Delete-land: gone for good. There is no way to reprogram it to send to Trash. One can, alternatively, hide it on the main screen by setting swipes left and right to None. But it is still there in the Read screen....and potentially dangerous. If you try to set a swipe to Trash rather than Delete, there is no Trash option. So you have to set it to Move and choose Trash each time. This reduces the utility of Tbird Android and means you have to be extra-careful when reading emails.

Also, no way to reduce image sizes (by percentage) when attaching large picture files...unless you reduce them in advance in an image processing program.

the settings ExtessionSettings does not show up to be able to modify even tho it is on the ADMX file (5.11)? Should I use the older Extensions policies? I want to install and pin an extension from the store.

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

your layout is fine when I first open the program but when an email is selected to be read, the left email folder list disappears and is very difficult to get back up. there must be an easy setup fix to this or else I am about to uninstall Thunderbird! And your service stinks like all the rest of BIG tech these days. Truth is you have now Customer Service.

I need to be able to hide the Extensions button from the toolbar. Is there a way to do that outside of the user.js or prefs.js? Preferably I'd like to do this though the policies.json file though I could not find any options for this.

I recently updated from Windows 10 to Windows 11 and have been using Thunderbird for my 4 email accounts for about a decade. Since the update, all my sent messages have a > sign next to them which I have to click on to view the various messages sent to the same person, with the latest message chronologically displayed near the bottom of the grouping. My thread option has been unselected. This is a new and unwanted layout and I only wish to see my emails displayed individually and chronologically, with the most recent near the top. How do I remove these groupings with the > icons and just see each message displayed individually? My frantic research only points to installing/selecting an 'add on' perhaps. I just want to see my sent emails individually like I have for the last decade as well as in my folders from previous years. SEND HELP!

I would like to stop version 146.0.1 of Thunderbird from loading yahoo mail when executing Thunderbird in a annoying new window. Just started happening 01/05/2026. Thank you Jeff

Bonjour,

J'envoie, depuis une mailing liste d'OVH, un mail présentant l'aspect suivant : une image encadrée (cf: PJ) Lorsque je le réceptionne avec Thunderbird, seule l'image apparait (cf: PJ)

Le code source de cette dernière montre que le code html du cadrage est présent. Un réglage bloque la lecture de l'html ?

Que se passe-t-il ? Merci de votre aide.
