The File (saving to a folder) Recent function used to have the folders alphabetically. Some genius thought to reorganize the Recent folders to be in chronological order. Is there a setting to have the Recent folders be in alphabetical order again? I could not find anything. Thanks in advance.

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?

As the topic says, the message list turned from the usual dark-mode look, to a full black background after updating to 151.0.

Was this an intentional change? How can I revert it?

Hi

When Thunderbird is started maximized it overlap taskbar if is set to hide and taskbar won't show until Thunderbird is minimized and maximized. Another way is to press the Win key two times. Then the hided taskbar can be shown/use. The same thing happens to Firefox. Only when is first started. Then if Firefox is minimized and maximized, press Win key two times, press F11 two times then the hided taskbar show/hide normal.

It is a setting that can be changed to start Thunderbird and Firefox in full screen and do not overlap hided taskbar?

Hi,

I am trying to edit my message separator line (which I added many years ago). Now there is a big gap in the line and messages. How can I reduce this gap please? Any advice?

I have one file folder that I moved certain files to that once read, they are not visible or listed in the folder. The folder massage count is 296. When I move an email into the folder and it is not read, I can see the message. Once read, it disappears. I can filter by attachments and contacts and see some but not all of the messages.

I just installed Thunderbird on an up to date Windows 11 PC and unchecked the box Automatically mark messages as read, but it keeps marking all of my messages as read.

Help please!

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?

after setting up a new install on another pc (ver148) and moving the profile folder over,

the only issue i have so far is the little yellow star in the folder for new mail having arrived in is not showing up. it will show the number of new msgs on the taskbar icon only.

can this be fixed?> can seem to see it in settings.

image attached of how it looks on the old pc

thanks

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?

I have Thunderbird on another PC that shows the incoming emails with the contents with the contents displayed under the email list, yet on my new PC I cannot seem to get that setting. I have to double click an email and it opens a new tab. I have used your help and also YouTube to no avail.

For some time the feature to use color in text has not worked. I deleted and re-installed Thunderbird but no change. I cannot change the font color when typing an email, and making changes in the settings has no effect, either.

I have my "signature" saved as an HTML in color, and it also will only display in black.

Any articles and solutions posted seem to be for people using Macs or some other kind of computer. I have Windows 11 for a Lenovo Idea Pad 5. Thank you in advance for any and all guidance you can offer.

Whenever i send a message , it is saved to the 'inbox' previously it would be saved "sent mail". I have verified that TB is configured to save to sent mail but the msg is saved anyway to inbox.

Can some one explain how to get back to saving sent messages to sent mail folder.

In all honesty I find it frustrating to keep moving msgs manually.

Around early December 2025, right after a new Thunderbird release (I forget the exact version number), there was a change in Thunderbird’s behavior when I click on “Write new message” on Thunderbird’s jump list for its pinned icon on my Windows Taskbar.

In the past, Thunderbird would simply open the composition window by itself and I could get right to typing the new email.

Now, however, after the early-December release, when I click on the same jumplist shortcut, Thunderbird opens BOTH the composition window AND the main Thunderbird program window along with it.

Is there a setting (maybe in about:config?) where I can revert Thunderbird to only opening the composition window?

A few weeks ago, I had to re-add my email account in Thunderbird and took the opportunity to switch from POP3 to IMAP. I am generally familiar with the synchronization behavior associated with IMAP. However, I did not pay close attention to the Sent folder at the time, and I have now noticed that there are almost no sent emails stored on my local computer. When I checked with my email provider (freemail.web.de), I discovered that the retention period for sent emails is limited to 30 days. Apparently, the sent emails (in the “Sent” folder) are synchronized with the server and are therefore deleted from my local system as well once they are removed on the server.

I have now increased the retention period on the server, but I would still like to clarify the following points:

• Is the synchronization of the Sent folder in fact intended to mirror the server folder (i.e. including the deletion of emails)?
• If so, is it possible to configure the synchronization to be one‑way only (i.e. that new emails from the server are added locally, but emails that are no longer present on the server are not deleted from the local Sent folder)?

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'm on a new Windows 11 desktop with two monitors. Everything's been working just fine up until around 26th April (two weeks ago) when the native Thunderbird new mail notifications started appearing in my second monitor, rather than my main display. I had made no changes at all myself.

I've been through all the fixes suggested via Google (toggling the displays; checking Windows notification settings), but none of those fixes have made any difference. I switched to using Windows system notifications for a while, but I really don't like them.

Might this be something in a Thunderbird update itself? It just doesn't seem to be detecting the primary monitor at all. All my other app notifications continue to show on the primary display.

Has anyone else encountered this or have any other solutions I could try?

Thanks, Averill

Have 3 gmail accounts 1 icloud account all are appearing and working, but can't get unified inbox to display anything even though there are emails in all accounts.

How does one add additional fonts to Thunderbird for use in composing email messages?

Appreciate.

OTHER: Someone needs to revise and update this form! "Thunderbird version" (below) now prohibits inputting the complete length of Thunderbird's version; limits to "18 characters"; version is now 20 characters. Website input forms that have unrealistic character limitations really irritate me.
