A fair number of folders in my primary email address's inbox have been out of sorted order for at least several months.

Most of them are folders I access quite often; they now appear AFTER what used to be the last folder ("Zoom").

If this is a "feature," I suggest moving the highest activity folders to the FRONT of the inbox rather than to the BACK.

HOW DO I RE-SORT MY INBOX FOLDERS?

Thank you.

These are technically two separate issues, but both pertain to functionality of the mouse and keyboard. Whenever I right click to bring up the menu, the options (despite being functional) do not appear in the menu proper. Instead there are just empty buttons. In addition, certain hotkeys aren't working at all. Ctrl+C and Ctrl+V to copy paste are doing fine, but Ctrl-T and Ctrl-W to open and close tabs respectively do nothing. Neither of these issues were happening yesterday.

I've had a total failure and reinstalling Tbird anew. My inbox only shows incoming msgs and not the texts in a box on the lower section of the page. I have to double click to see the msg. How do I fix or am I gonna have to adjust to the new reality. Thanks for your time.

Since a recent update, I am finding Thunderbird almost unusable.

Problem: It is linking emails together that I want to be separate. It shows a little arrow next to the Subject. Is this called Threading?

I just discovered replies to emails this morning in these threads that have not shown up to me as a new email coming in. I've just taken people to task for not responding, when they actually did... days ago.

I can't find any way of stopping the emails linking together. I need all these linked emails to be separated.

I just sent a test email to myself. Then sent a separate test email to myself with the same subject title and they are now linked together. I can't use a system like this.

I've unticked the 'Thread' command in the drop down menu, but that doesn't help.

Is it possible to unlink them all?

Thank you. David Ashworth.

NOTE: I do send you a monthly donation.

When using Thunderbird 140 I am able to setup the background color of the message pane for individual messages. However when the messages are threaded, the message pane shows a preview of all of the threaded messages together in the message pane with a different background color than individual messages.

At one time before several updates ago, all messages in my inbox were separate. After a previous update, reply or messages with the same header started be be nested, each one showing only the sender and the subject, which is now the same. I am forced to read through them all to find the one I want. Deleting any in the change can be hazardous.

How to go back the old way of message display?

Hello! It seems Thunderbird emails are suddenly being 'threaded'. It is causing great confusion in my office.

I need to see each email from a person separately in order to find them easily and also to reply to each one at the time it is received.

Can someone please explain in very simple non-techy jargon:- a) How I 'unthread' messages already threaded AND b) How I stop any new ones being threaded in the first place.

Thank you Tylex

Hello people,

When I compose a message in my word programme (Softmaker or Libre), save it in Docx format and copy/paste it into Thunderbird to send it everything is double spaced and nothing I do in the "compose" menu can change that.

I have tried it with "Use Paragraph Format" checked and unchecked and it stays doule spaced and nothing I can find in previous threads seems to address this problem.

What am I missing?

New messages received by an email account are scattered at random in the inbox instead of being at the top of the list. How can I ensure that the inbox has new messages at the top?

MY SYSTEM: Thunderbird 140.5.0esr running in Linux Debian Bookworm

I have created a filter from a recently received message via pop. The settings are: OK Manually Run OK Getting New Mail: Filter before Junk Classification

Match all of the following From Contains xyz.co.uk

Perform these actions: Move message to XYZ on my mailbox

Press OK

In the Message Filters window, Run selected filter(s) on: XYZ Press Run Now

There is no response, and all the messages remain in the Inbox.

I have repeated the Run Now process on an old filter (by moving the message back to the inbox), and that works fine.

The only oddity of the current message is that it is a no-reply message eg From = no-reply@xyz.co.uk

Any ideas welcome!

After the last update, I found that when I point to a message it is highlighted in red. The choice to send a new message is highlighted in red. I find the color garish and want to reset it. How an that be accomplished? Or, can I revert back to the last version while I look for another email app. I have been a supporter for a very long time. I have used this product for more than a decade. I don;t want to switch but ...

Hi, I dont know what setting I have accidently changed but before I used to double click a new message in my inbox on local folders and now instead of reading it full screen now it wants to send it as an email message to someone!

Any ideas to put it back to just read the email and not compose a message with it?

Thanks.

I dont remember having this 'new message template' thing before when I right clicked on a message in my inbox , maybe thats what the issue is?

Amazon just sent me an email an animated GIF at the top of it. As a result, whenever it's in the preview pane, it's constantly swapping colors and making a visual nuisance of itself. All morning, it's been blinking at me. Is there any way to shut off animations in the preview pane? I almost never want to see an animated gif in an email, but I definitely never want it dancing around in the preview pane.

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 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!

Når jeg sletter en mail vises på bundlinien ikonet at der stadig er en mail så ikke er læst. Først når jeg trykker på en tilfældig fane forsvinder det. Hvordan kan det ændres.
