Thunderbird Community Forum

Just installed Thunderbird on a new laptop running Windows 11. Accounts are set up and I can see all the emails in my inbox. They are in the Table View. My problem is that I can not view the contents of the email. I used to be able to click/highlight a message and its contents would be displayed below the list of emails. I am unable get this view. Can you please help. Thank you, Jim

I believe that version 145.0, newly installed on the 9th December, 2025 was showing server folders correctly; the server folder name matched the client folder name.

After upgrading to 146.0 on the 10th December, the server folder names for some folders are displaying with different client folder names.

The IMAP account has both "spam" and "junk" folders, Thunderbird is now displaying both as "Spam", you can only determine which folder is which by showing folder properties. It appears to users that there are two "Spam" folders now and not the two distinct folders with their own names.

Similar behaviour is happening for "Sent" and "Sent Messages" folders, both now display as "Sent".

These changes are confusing, the client sees two "Spam" folders and two "Sent" folders instead of the original proper server folder names.

Why has the display name for these folders changed?

How can I get TB to display the real underlying folder names?

I want Thunderbird to stop marking everything I delete as having been read. The way it works now, if I accidentally delete mail that I haven't read yet it's much more difficult to find it when everything is marked read even when it wasn't. I searched everywhere and haven't come up with a solution for this. It was reported as a bug years ago and was never fixed.

When I delete a message from the message list panel, my TB used to reach a state when no message is selected. Now, after a message is deleted in the list [classic view, message list panel], another mail is automatically selected. Is there any way of getting the previous behaviour? Thanks in advance, Max.

My wife and I have separate emails and we also share an email account. My laptopn has Thunderbird profile set up to receive from both and data is held on our local NAS Wifes Laptop does the same and her data is on her folder on local NAS. For the shared email, we can each access and it creates a local copy on BOTH of our respective folders on the NAS. Whilst this works, i cant help wondering if we're setting up a sync loop. THe shared email isnt used much, but is there a way that we can share the exact same files /data for the shared email on the local NAS. ie. Still have one view in Thunderbird client but have the shared email data be on a common shared folder. Still keeping our separate profiles. This worked for Outlook pst files. But New Outlook is a disaster hence moving to THunderbird. . This seems to be a simple scenario. 3 email accounts 1 shared. 3 local data sets. One shared. 2 separate laptopns and THunderbird installations. One common local NAS. ANyone have any guidance for best practice ? THanks

When in dark mode, forwarded emails: • Are not in dark mode notwithstanding that new emails are. • Bear no resemblance to the email being forwarded whatsoever, with boxes all over and colors completely different not only from those in the email being forwarded, but also from those specified for emails being sent. • Resist configuration of body text, so that not only is the background white instead of black, text remains white or a very pale yellow but illegible in any event.

Does anyone else increase the size of the Thunderbird window hoping to see more of the email in the message pane? But instead, we just get a longer index of messages. Then have to move the border of the message pane up. This is only for the occasional need to see more in a single page, but frequent enough that I'm repeatedly having to resize the pane for individual message, then resize it again when I return to my normal window height. Yeah, I know I can open in separate tab, but seems allocating the space to index/message pane on window resize, ought to at least be done equally, if not all to the message pane.

Is it possible to open incoming mails in the same window as the list of e-mails, just like in Google? I get distracted from seeing suddenly my e-mail in another window/tab.

Thank you!!

Hello,

This is the second email I am sending to get help.

I selected my composing font type and color in setting. When I start to compose an email, the font type and text color are shown as I selected. However, as soon as I start typing the text, the color goes to default (black).

Please advise,

Surendra

I find using format painter is so useful to correct font type and format when cutting and pasting from other sources. Is there a plan to add this to the Thunderbird email portfolio? If not, how can I correct font size and format because when I use the drop down menu, the request is ignored or corrected to something close but not exact, even if I select all the text to format it in one single type and I still end up with text in all sorts of crazy formats.

When clicking any hot link in an email, whether FB or a web retailer email, etc. this message pops up: "This file does not have an app associated with it for performing this action. Please install an app, or if one is already installed, create and association in the Default App Settings page."

At a loss for a solution here. Can someone please help. Thanks.

I'm running Thunderbird 140.5.0esr (32-bit) on Windows 10 Pro Build 19045. After the last few updates the columns in the email listings are changing widths from what I've set them, this seems to happen after I close then reopen Thunderbird; which I'm having to do more often these days to resolve weird calendar malfunctions. For instance, the data column would appear so narrow that only the month/day show with "..." at the end, when I know I've looked at this yesterday with the full view of the date and time showing. I've reviewed my options and I've set them individually, set them globally and it makes no difference. Of course I've rebooted, etc. I have over a hundred local folders and they all change differently, of course some look the same but others don't. Most have the same column headings selected but it doesn't seem to matter. Some have the "Correspondents" column selected but many don't.

This is very irritating and I'd like to know why Thunderbird is doing this, and more importantly, how can I prevent this behavior in the future. Thanks,

I recently installed 145.0 on Windows 11. It defaulted to a different view (Card view and the message list shows Name and Email). I changed it back to Classic and Name only in Settings, but each time I close and reopen Thunderbird, it changes back to Card view and Name/Email again. Any suggestions on how to permanently switch this to "Classic" and "Name"?

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

How do I stop Thunderbird 115.10.1 closing tabs by itself? Previous version (I don't know what previous version I was running before the inadvertent forced update to 115.10.1) would leave tabs open until I manually closed a selected tab. How do I get 115.10.1 to perform the same way?
