Thunderbird Community Forum

I have the up to date versions of Thunderbird on my desktop and laptop.

The buttons to check for new messages and compose a new message are visible at the top of the account list on the desktop, but not on the laptop.

I can't see anywhere in the settings on the laptop to show those buttons.

Jag har köpt ny dator och vill flytta alla lokala mappar och kontakter från mitt gamla Thunderbird till mitt nya. Jag har öppnat profilmappen och försökt kopiera in den, men inget händer!?

While in offline mode I composed an email and chose the 'send later' action. I want to revise the email or prevent it from being sent if that's not possible. When I switch to online mode I get a dialog asking if I want to send the emails I chose to 'send later' now or later, but I cannot find a way to permanently prevent a certain email to be sent. How can I solve this?

I described this problem on this forum a couple of hours ago--but I now know any response to help me will come via email--which I cannot access due to the password problem. I was using Thunderbird mail when up pops this pop-up asking for my password. I have never had to use a password to access my emails with thunderbird email. I tried a Yahoo mail password, a mozilla account password, a thunderbird account password--none are wanted. I can't find where to change a password or add a new password.

How can I get some help not sent via email.

I have Comcast as my ISP and my mail comes from Comcast using Thunderbird. I got hacked and bulk messages sent by the Turds. A lock has been put on Outgoing Mail. I went to Comcast and I can SEND through that, but I cannot SEND through Thunderbird. I get this weird error message. See the image below.

HELP!! How do I get Thunderbird's error message fixed so I can send messages.

I am trying to figure out if it is possible to export (or download) the mail subfolders from my email account to my PC. My aim is to be able to access and review them offline.

Thanks.

Hi,

I would like to integrate the user's address book (or more specifically the contact details of the current user) into my own (c++) desktop (Windows/MacOS/Linux) application for the user's convenience.

Is this possible at all? If so, where can I start reading to find out how to do this?

(If it's not possible through an API, is the address book file format documented somewhere, so I can read it directly?)

I don't need write access. I just need to be able to read the user's contacts.

Cheers, James

I tried to enter new addresses *.csv via the import function, but I am not getting the desired result. Please provide instructions! The result is in the attachment.

About a month ago I began the process of upgrading from W10 to W11. In the process, several problems happened. One of the problems was with Firefox. After reading and trying many suggestions from the Mozilla site, as well as several other sites, and having no success, I posted my problem on this Mozilla support site and hope that there was someone who could help. There was. After several days of exchanging messages (suggestions, instructions and results - mostly about Profile), Firefox returned.

The other major problem is Thunderbird. I have downloaded a current version (128.5.2esr). I have run it twice and, each time, email was downloaded. So that part seems to be working. What doesn’t appear are the settings I have used and message folders I have created over several years. I suspect that the problems are Profile related.

Starting from Help in the Thunderbird menu, then Troubleshooting Information, then Application Basics, I see Profile Folder. On that line is a button labeled Open Folder followed by (Local Drive). I click Open Folder and File Explorer opens to a folder named ab3xaztm.default-esr. It shows that the folder contains 59 items, including 10 subfolders. All files and folders show a December date.

Following the path C:\Users\rsuth\AppData\Roaming\Thunderbird\Profiles\, in addition to ab3x…, there is another folder nlys3gkl.default that contains only 1 file, times.json.

Because of my earlier struggle – and eventual win – with the Firefox problem, I think that the Thunderbird problem might also be fixed in a similar way: Profile.

Slightly before the upgrading from W10 to W11, I made a copy of my Thunderbird folder. I think if I replace the currently active Thunderbird folder with the one I have saved, my Thunderbird problem may be over. However, I’m not certain that will happen and I’m not certain about the specific steps to take to make the replacement. (With my Firefox issue, there were a couple of small important steps I had to take to make it work, and those steps were explained to me by the person who helped me with my Firefox problem. So, after all these words, can someone point me in the direction to solve my Thunderbird problem?

Thanks for reading.

I've been using Thunderbird for years. I shutdown my computer (MacOS Sequoia) and went away for a few days, and now Thunderbird hangs when I try to use it. I have one main email account which I access with POP, and a couple of other accounts which I access with IMAP. I can access the downloaded messages in the Inbox of the POP account that I downloaded before going away, but I can't read any other folders (I have many folders since I've used Thunderbird for so long), or access the IMAP accounts. Thunderbird shows that I have new mail waiting on the POP server, but it hangs when I try to download them. It does not show mail waiting on the IMAP accounts, although I know new mail is there.

I have tried re-installing Thunderbird, and rebooted the computer, with no change. When Thunderbird hangs, it eats memory until the system runs out, and I have to use Force Quit to terminate it.

It's the first time I've had a problem with it!

In certain instances, I can no longer copy/cut from Cardbook notes. This happened in last few months. I just have time now to post the problem. I know since then Thunderbird had updates and so had windows. I am on Thunderbird 128.5.2esr and Windows 11 and firefox 133.0.3 I used to be able to select a word or many words and then right click. Then copy or paste would show up as option in a list. Now no list shows up. But control c and control v sometimes works. If I control c and control v within the note that works. I can copy from something like Word and control c and paste using control v and vice versa. But if try control c in notes and then control v in website that does not work. And that is what I use most.

The path to find stored passwords shown in answers to previous questions is: Tools>options>privacy & security>Passwords. Click 'show passwords'

'Options' is no longer listed under 'Tools', or anywhere else that I could see.

I looked under 'Settings' and 'Account Settings', because I seem to recall it being shown after I scrolled down under one of those headings, but could not find it there.

Please tell me how / where to find stored passwords now.

I love Thunderbird. It is fast, robust and efficient. But now, every time I launch the app, it is in dark mode and it is difficult for me to use it because of my terrible eyes. How can I turn off dark mode ?

I use Thunderbird on Fedora 41 Gnome. Thanks in advance for your help.

All of a sudden the font alignment in my inbox looks really strange, see image, i don't know what happened i didn't change anything, i did restart my computer this morning. I'm on a mac running Sonoma 14.7.1 , thunderbird 128.5.2esr (64-bit)

any ideas what's happening here? thank you!

A couple of months ago Thunderbird started being very slow in multiple situations. I use POP3 and download all mails. I have fairly big mailboxes, some of them up to 2½ GB.

1) Downloading e-mails is slow.

But the worst is this one:

2) Clicking on unread mails first time. This can easily take 10 secs, where the app goes "not responding" and finally "Loading message...." With 10 new mails, it is a lot of wasted time.

3) Dragging mails from one mailbox to another Some of the same behaviour as above.

I have tried to compact mailboxes, but that doesn't help.

I am on release 128.4.1esr (32-bit), windows 10.

I am having a problem syncing my Thunderbird folders with iCloud. Every time I have to explicitly check that I want to subscribe to all IMAP folders in my iCloud account. Then after a short while a lot of folders get unsubscribed and I have to subscribe them again. I have experienced this instability with both Thunderbird and Betterbird as well as on Windows 10 and Pop_OS! 22.04. More people have reported the same issue, but no solutions have been shared:

• https://support.mozilla.org/en-US/questions/1441368
• https://support.mozilla.org/en-US/questions/1444029

Does anyone know how can I fix this?

Thunderbird suddenly can't connect with my email servers. A box from Xfinity pops up: • Xfinity: Sign in with your Xfinity ID (for ***@comcast.net) • but when I do: Access Denied You don't have permission to access http://login.xfinity.com/login on this server. Reference #18bffcc317.1734841179.1c89c1f5 https://errors.edgesuite.net/18bffcc317.1734841179.1c89c1f5

Also Thunderbird error messages: • Authentication failure while connecting to your server imap.comcast.net And Thunderbird error message: • ~Connection to yahoo timed out And my Inbox messages don't show

Please help. I see no cause for this, didn't download anything today. Thanks, Lynn
