I have Thunderbird 148.0 with windows 11. I have 5 email accounts. How do I turn off those unwanted and unneeded notifications of email messages. There are TONS of them and they are very irritating and serve no useful purpose that I can see.

There is a way to add a folder to a Thunderbird account that combines other folders. The one I want to create would be "Inbox and Sent emails combined". I did it in the past, but I can't remember how to do it anymore. Can someone help with this? I am running Thunderbird 140.8.0esr (64-bit) on Linux Mint.

i am confused at this point: Double-click toolkit.legacyUserProfileCustomizations.stylesheets to true in Settings/General/Config. editor, restart TB.

The row background and text colours can be set with css (see picture):

/* row bg, text colours for selected messages table view*/ tr[is="thread-row"].selected {

 color: white !important;
 background-color: red !important; 

}

Help/Troubleshooting Info, Profile Folder, Open Folder, close TB, create a new folder named chrome, create a new document in chrome with a text editor, name it userChrome.css, Save as type: All files *.*, copy in the above code, change the colours as desired. Double-click toolkit.legacyUserProfileCustomizations.stylesheets to true in Settings/General/Config. editor, restart TB.

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?

I have a MacAir and want to create a signature with a Brush Script font. In the Thunderbird Account Settings, I see the area to create a signature but not a list of fonts. How do I do that? Thanks, Richard

I have version 146 of Thunderbird. My OS is Windows 11. The Local Folders in Thunderbird are out of alphabetical order.

I have list of 130 local folders that are in the correct alphabetical order. Under that list, I have another list of 25 folders, starting with the letters L - U, that are in order alphabetically. I have tried to move several of them back up into their correct place in the list of 130 folders that are above them. This worked well for about 10 folders. Now, when I try to move a folder from the second set to its correct place in the group of 130 folders above them, they all end up in the same spot, between folders starting with De and Dra. When I try to move them away for this location, into their correct alphabetical slot, they will not move.

Also, when I try to create a New Subfolder under Local Folders, it is not created in the correct alphabetical location.

Does anyone know of an easy to correct these errors? I need to get my local folders in the correct order alphabetically again. 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!

I have rules. Email goes to folders based on rule. I want to reply to an email and have the reply stay in same folder. How do I fix this to work again? What is happening only some out bound emails go into "sent" folder.

When I tried to import my OpenGPG keys from the "Select File to Import...", I found that it cannot display the hidden files or directories.

Did I miss a setting for this? What can I do to show the hidden files?

I use Thunderbird on my desktop and laptop for my mail. I use Outlook on my Android phone. When I delete old messages from my SENT MAIL folder on the computers, it doesn't delete from the SENT folder on my Android Outlook program. What settings do I need to have it delete in ALL places from SENT when I delete it in any one place. Thanks for any help you can offer.

I had at least 10 message filters to sort my inbox into subfolders. Twice in the last 4 or 5 months all but 4 of those filters vanished. The subfolders were all there and contained all the messages previously sent there by the filters. New messages were still in the inbox. I neither deleted nor disabled any filters. I did notice that one of the filters which I had renamed a few weeks ago had reverted to its old name. Having to redo these filters every few months is tedious and unacceptable. Please help.

I currently use imap with my email hosting provider and has worked well with Thunderbird. However, speeds are getting slower and storage costs have gone up. It is time for me to move non-current emails from my email account to back it up while still accessible. I was wondering if Thunderbird's Local Folders default path (C:\Users\......\AppData\Roaming\Thunderbird\Profiles\......\Mail\Local Folders) can be changed to a google drive folder on D:\ drive. If there are any risks in doing so. Thanks.

The Braille Institute has developed fonts that are 'hyperlegible'. How do i make "Atkinson Hyperlegible Next" the default font for headings, toolbars, message list, etc?

Bonjour, j'utilise Thunderbird sur MacBook M3, MacOs Tahoe 26.2, sur Thunderbird j'ai 3 comptes messagerie .bbox et un compte .gmail dans le dossier envoyés de chacun de ces comptes ne figurent QUE les messages envoyés du mois en cours ou du mois précédent si aucun message n'a été envoyé le mois en cours aucuns des messages envoyés auparavant ne s'y trouvent. Tous les comptes sont en mode IMAP J'ai vérifié les dossiers sélectionnés dans les paramètres des différents comptes et le dossier envoyés est bien coché dans chacun la méthode d'identification est bien Oauth2 pour tous... Le problème étant présent sur les 4 messageries et pas seulement sur la messagerie gmail il me semble que ce soit un problème de paramétrage Thunderbird... Merci de vos retours

i manage 8 email accounts for different projects I run.

When I open thunderbird, all my folders in each email open up. Is there not a setting to say don't open folders?

In my current version of Thunderbird, new messages show a dark blue subject line only until I click on them. After I open the message once, the blue highlight disappears. Is this the normal behavior now?

Is there any way to extend that same dark‑blue highlight to other emails as its really helpful to provide good contrast between individual emails.

Thanks, Steve

I’ve been troubleshooting the compose‑window font behavior in Thunderbird and discovered something that seems inconsistent from a user‑experience standpoint. After resetting all the font mappings (Proportional, Serif, Sans‑serif, Monospace, Minimum font size, etc.), I noticed that the font used in the message body can never match the font used in the Subject line or the rest of the Thunderbird interface. The Subject line and UI elements use Segoe UI, which is the standard Windows system font. However, Segoe UI does not appear anywhere in Thunderbird’s compose‑font dropdown lists, even though it’s clearly installed and used throughout the rest of the application. This creates a confusing situation: - The interface uses one set of fonts (Windows UI fonts like Segoe UI) - The compose window uses a completely different set (web‑safe/message‑safe fonts like Times New Roman, Arial, Courier New) - The user cannot choose the same font for both areas, even if the font is installed on the system - The dropdown lists in different parts of Thunderbird do not match, even though they appear to be selecting fonts from the same computer From a user perspective, it would make much more sense if all font dropdowns in Thunderbird used the same unified list of system‑available fonts, so the user could choose consistently across the entire app. Right now, the separation between UI fonts and message‑body fonts isn’t obvious, and it leads to confusion when trying to restore defaults or match the appearance of the Subject line. I’m posting this to ask whether this limitation is intentional, a technical constraint, or something that could be improved in future versions. A unified, system‑wide font list would make the experience much clearer and more predictable for users. Thanks for any clarification Steve
