Thunderbird: форум сообщества

I just got a new Windows 11 computer. After installing Thunderbird 147.0.2 I noticed there were no columns at the top of the message pane as there had been in the past. I read articles about how to add the columns but could not find the column icon or anything in the header area that allowed me to do what the articles recommended.

I want to add the columns for sorting purposes from time to time but I can't find a way to do it. HELP!!! Please?

Thanks, Clyde

I have been using Mozilla Thunderbird for decades and they have even contributed a small amount of money to Thunderbird periodically. Just within the last two or three days all of a sudden I have been unable to send emails with my phone. I receive emails, but I do not send them. So I opened up a laptop where I did not have Thunderbird and set it up properly through Spectrum using the incoming and outgoing servers as mail.twc.com. and yes, just like on my phone. I continue to receive new emails, but even with the laptop I was unable to send an email. I received the message"send message error sending a message failed. The message could not be sent because the connection to outgoing server smtp mail.twc.com was lost in the middle of the transaction. Try again."I contacted Spectrum twice and both times they had me try to send a message through their Web server spectrum.net and that message did go through. Of course then their response is that this has to be a problem with the third-party app meaning Mozilla Thunderbird, and they can’t help with that at all. I sure would appreciate some help because I hate to walk away from Thunderbird as well as change my email address after all of these decades.

How do I import *.ICS file in a reasonable amount of time. I have appointments in an ics file of less than 1 K in size, typically 700 - 800 bytes in size and they take HOURS to import and do not connect properly then to allow editing the appointment. This is from Baylor Scott and White, a major hospital system in Texas. If there is a problem with the imported file structure, please point me to the correct file structure. I like Thunderbird, but this part of the calendar is very frustrating. Clarence

Hi all,

I am new to a Mac (1 year now) and am trying to make Thunderbird work for me as I have not been happy with other mail clients. I am struggling through a few things.

I like to navigate by keyboard if possible. In the Calendar tab using a month or multi week view, the "[" and "]" move month by month or week by week in multi-week view. How do I move to the next day or two using the keyboard?

A big thank you to all who reply, and sorry if this question has been answered many times before (I did not find the answer in the keyboard FAQ). --Tim

Good afternoon, Since yesterday, I have been having a problem where new messages can no longer be previewed or opened. Emails can be sent, but they do not appear in the sent items folder. Everything works fine on my Samsung smartphone with the Samsung app.

Kind regards and many thanks, Marcel

My Outlook account moves what it thinks are spam/marketing messages into a "Junk" folder. Sometimes there are important messages here that I must mark as "Not Junk" so that I can continue to receive new messages from this sender in my InBox. I cannot map this Junk folder into Thunderbird even after I go through the steps and checkbox this folder to be synchronized. It does not appear in the left-side "All Folders" section.

Many solutions suggest that I make changes in "Settings\Privacy & Security\Junk" section. This does not exist. There, however, is a "Spam" section. Is this the same functionality?

Further, under "Accounts\Spam Settings\" there is a "Destination and Retention" section. There is no "Junk" folder available under "Other".

Does anyone else have problems linking server-side Junk folders into Thunderbird?

Thank you in advance for taking the time if you replied, Tim

ps. I've googled this extensively, and all the presented "solutions" are not accurate as the Thunderbird "junk" options they refer no longer exist. Has there been recent UX changes, and this is now a lingering bug?

I am really in a panic: Using ubuntu 22.04 and Thunderbird 140.7.1.esr For my main account I keep some 40 sub-folders and sub-sub-folders. All but the most recent mails in my sub folders are gone, something like 4 years of email. I asked chatGPT for help and found inside the /mail folder that most of the files with the names of my sub folders with no extension have 0 kb. I don't use IMAPS because I wanted my mails on my computer so I use only POP. :-( The interesting thing is that this only happend to my main account. I have 6 more accounts in Thunderbird and they seem to be fine, at least for now. Thank you for any help. Kind regards Frank

Trying to send mailmerge. Thunderbird version 147.0.2 (64-bit) I have sent a mailmerge from thunderbird before, so it should work. I have my CSV ready, and I type the email draft. I click the mailmerge icon, and fill out the mail merge dialogue box. After I fill out Mail Merge dialog box and click send, a blank dialog box opens, then I can't do anything (my email draft is frozen)tried sending, and saving, or pressing load (all options highlighted in screenshot). See also screenshot of blank dialogue box and frozen message. I tried closing the blank dialogue box, but the mailmerge is not sent, and after that, I can create a new message, but the mail merge option is greyed out, so I cannot select it. So I shut down Thunderbird and restart, then I can click the mail mergeicon,but same problem,I only get as far as the blank dialogue box. Thank you so much for your help

Every 2 or 3 days, Thunderbird tells me it needs to be updated. I run the update but halfway through it stops and tells me that I have a newer version on my PC. Why can it not recognise that I am up to date?

A satisfied user of TB on Linux for many years, about 3 months ago I lost many recent messages when transferring from an ancient laptop running Ubuntu to a new laptop running Fedora 42.

I installed my entire file system, including the .thunderbird directory in the home folder, on the new machine from a Duplicity backup of the old machine (BTW, I've now switched to Restic). All my files seemed to be just fine, except that when I opened TB, most messages in local folders that had been received earlier in 2025 were missing.

Hoping the problem was a defective backup, I made a new backup of .thunderbird on the old machine and copied it to the new machine. Nothing changed.

Thinking that Duplicity might be failing to backup TB files correctly, I then decided to copy .thunderbird itself (i.e., the directory and subdirectory structure and all files therein themselves) directly to a USB stick and attempt to restore from that. Unfortunately, the old machine then failed to boot up. Since then I've been making with a big gap in recent email history.

With a bit of spare time over the holidays, I've finally managed to boot up the old machine. TB running there shows the messages missing from the new machine. I have copied .thunderbird to a stick, as I had wanted in September. The problem now is that I cannot simply copy my old TB profile to the new machine, because I'll lose the last 3 months of locally stored email traffic.

So, how do I get the lost messages onto my new machine without losing recent messages or creating loads of duplicates?

Dear Thunderbird Developers,

I am writing to express my frustration regarding the recent UI changes. After the latest update, the standard toolbar icons (Get Messages, Write, Address Book, reply, etc.) completely disappeared for me, leaving behind nothing but a search bar. Even using the "Restore Default Set" option fails to bring the essential navigation buttons back. While I can eventually fix these issues as a power user, these constant, breaking UI changes are a major problem for average users. For instance, my 65-year-old mother relies on a stable interface. Every time a rollout breaks the visual layout or hides basic functions, she is unable to use her email until I step in to fix what the update messed up.

Forcing users to manually rebuild their primary navigation toolbar after an update is not a "feature"—it’s a regression that alienates long-time especially elderly users who need reliability over constant redesigns. Please prioritize UI stability and ensure that "Reset to Default" actually restores a functional set of icons.

If you need further information I'll be glad to hear and hope you can give me an easy fix for this problem.

Dear all,

I would like to use Thunderbird on a shared computer at my universitys lab space (it is mainly my PC but other people have access and use it sometimes). However, as we are requested to keep mails confidential I thought it would be as easy as just setting a primary password and thunderbird would not start if that password is not set. However, that proofed to be a wrong assumption. Instead if I just cancel the dialog it will open and still display all the locally stored mails.

We are using IMAP server and I already set up that the mails are not stored locally. Still, some mails that I have used recently are visible. I am aware that there would anyway be the local copy in the profile folder but I guess none of the people sharing that computer would take the efford to check that, so I would be fine if I could simply prevent thunderbird from starting without the primary password.

Is there any option for that or any extention that would do so?

Thank you in advance! Juergen

The month at a glance format was great. This new format(s) Feels like you fixed something that was not broken. I liked the old format. How can I get back to it?

Hello, I've just downloaded and started to use Mozilla Thunderbird on my Windows 11 desktop, and have encountered a strange problem. Whenever I compose a new email - it contains a lot of gibberish that looks a bit like a mixture of HTML coding and binary. I've tried changing the format of new emails between HTML and Plain Text and nothing seems to overcome this issue.
