I-Thunderbird Community Forum

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,

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 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.

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

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 see there are 3rd Party Message Filters. However, I'm not looking for those. I'm looking at the Tools> Message Filters>Filter name for:, where you can add Email Details>choose what part of the email, and then move Message to. I want to be able to view the Filter name alphabetically in the Folder(s)...without having to sort so many of them individually.

Example:

- Filter name: 123@domain.com - Match: From - Move Message to: Spam - Message Filters (alphabetically)

Any help would be appreciated.

What font can used in Thunderbird that will display a capital I with top and bottom bars? Otherwise it's impossible to determine whether the letter is an capital i or the letter L.

I recently moved thunderbird from my Win 7 laptop to a new laptop with Win11. All was OK for awhile. One day all of my Local Folders were no longer in alphabetical order. Some folders, like Outbox are under Local Folders. Is there a fix? Please don’t tell me to uninstall and re-install.

Using Acronis True Image for Western Digital (ver 2025 build 41936) to backup my files on a daily basis. Recently the backup program has been stopping and reporting that it cannot access some Thunderbird files, even when Thunderbird was not running (1st image) I tried 'Compacting all Folders' in Thunderbird but the result was the same (2nd image). Lastly, I tried clearing the cache - the result is the same. In all cases Thunderbird was not running during the backup.

i realize that this is not a Thunderbird issue, but I've been unable to get help elsewhere. I wondered if anyone might have a solution since Acronis apparently sees the file as being accessed - is there a way to remove that?

Greetings, Is there a way to change the order of threads in a folder? The all appear with the oldest message in the thread at the top and new emails that come into that bunch are buried at the bottom with no indication that they are there. I'd like to have the newest entry to the thread at the top and to have the threads with new messages highlighted until the message is read. Possible? Many Thanks

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

My inbox is now put in alphabetic order thanks to one of the newest updates. I want it at the TOP. Can you fix this? In Thunderbird I now have to manually drag it to the top each morning.

When I open email in outlook my Inbox still appears at the top where it should be.

I hope this can be fixed sooner than later.

If this isn't the right place to post this please provide an email to post to. The website is not user friendly enough to be of any help to me.

I tried the Toolbar fixes in this forum and got the menu to show up, thank you. (Any menu in Compose mode had disappeared. Actually, both Firefox and Thunderbird icons on desktop and Taskbar had disappeared as well, and I had to reinstate shortcuts. This may or may not be pertinent.)

But when I try to add "Send" to the menu, using customize, the "Send" icon is nowhere to be found as an option, so I cannot add it to the Toolbar in Composition mode. "Send" is grayed out in all bold textmenus. If I use Ctrl-Enter, message does get sent. Using Windows 10, still. Perhaps this is an upgrade issue?

I got the "Donate" screen covering my messages; I donated but the Donate screen still mostly covers my screen. The part of the screen I can see has a different view (layout?) from what I have been using.
