I use this computer remotely. When checking emails, I usually use other means (iphone, other computers) but occasionally need to send from here and use Thunderbird. The last time I accessed Thunderbird on this particular computer was about 45 days ago. (Windows 10) When I opened Thunderbird, none of the emails would download nor could I send out a test.

I've double checked my account configurations, uninstalled and reinstalled Thunderbird, deleted the email account and recreated the email account but still getting a configuration error. Emails are definitely going thru (in and out) from this account but not from this computer.

I also tried setting up a different email account which worked just fine on this computer with Thunderbird. But the one I really need won't set up. What could have changed in 45 days and thoughts on possible solutions.

Thanks for any ideas.

The Archive function is no longer an option from any of my Feeds accounts. I am not sure when it started because I only use it once a year or so.

I have found information on this issue but it was for Mail accounts, and the solution was not available for Feeds accounts.

Can anyone provide some insight on where I might find some info on how to resolve this issue?

I am currently on Thunderbird 140.1.0esr.

I have multiple gmail accounts set up on Thunderbird. They were all working fine until I traveled overseas and came back. Then, all of a sudden, 1 gmail account stopped working. The rest kept working fine. I checked the settings and they were correct. I removed the account and tried to set it up again (about 10 times), but kept getting the same error message: "Unable to log in at server. Probably wrong configuration, username or password." The automatic configuration passed and I even tried manually configuring to the recommended settings to no avail.

The only thing I can think of is that when traveling overseas and trying to get online, Thunderbird and/or Gmail asks for further security verification, and I just avoided using Thunderbird altogether while abroad. Upon my return, I started getting this error message. It is extremely inconvenient to have to use the Gmail interface for only 1 email (my main email!). Does anybody know anything I can do to repair this? I'm almost tempted to use another email client altogether to make my life more efficient as the new setup is not sustainable.

Hello all!

I use Thunderbird as a local archive for my email. I have two accounts in the application: my home email via my ISP (POP) which I predominately use and my gmail (IMAP) which I don't generally use. There are years of messages in folders and sub-folder under the POP account, but nothing under the IMAP.

I’m up to date with Thunderbird at v140.1.0esr (aarch64) on my iMac with Sequoia 15.8.

On 07/22/2025 I went to download some messages via my ISP POP account and saw that a whole bunch of my email folders no longer had any subfolders and were empty of any messages. Some were also duplicated. Please see the attached image.

I haven’t changed any settings in years, and I do not have any add-ins. One of the nice things about Thunderbird has been its solidity and simplicity.

After every session, I would empty my trash and compact.

Suddenly my email seems to be gone along with sub-folders while top level folders are duplicated.

Wondering if anyone has any suggestions on how to troubleshoot this? Since I don't do anything fancy with the application and with the suddenness of this issue, I can't image I'm the only person having it? I’m quite concerned I may lose many years’ worth of messages.

Thanks much in advance! CPRoot

This happens about every three or four major updates: After the programmers monkey with the interface, part of my personalizations disappear. This time, it's the text menus at the top of the screen. (And it's two computers since the last time I had a solution to this.)

The "menu hamburger" is not sufficient for touch-typists. I want the icons off to the right of the text menus, on the same line, the way it's been possible to establish since Tbird was in the low-30s for version numbers. Instead, the update refused to respect my personalizations, and hid the menu bar completely and makes it impossible to combine with the icons. I dimly recall that there was an about:config solution to this in earlier versions, but can't remember or find it (or confirm it would work with Eclipse).

When I try to log into a site I have used dozens and dozens of times in the past, I get the following notice: WARNING: POTENTIAL SECURITY RISK AHEAD. This is a dead end from which I have not een able to proceed. The particular site I am attempting to access is the only site where I've encountered this warning. I called that site and was told that while they have been tweaking their security, since the warning message came from Firefox, I should contact Mozilla for help. So here I am.

I use desktop Firefox with newly installed Windows 11 (my profile erroneously sates w10). i must use the blocked website frequently, and so I need to restore access to it ASAP. It is a high security healthcare site, and as I said, they claim they could not identify a security problem, that the key to restoring my access is through my browser, Firefox.

Can you help me restore my access to the site? Thanks .... KH

I am now receiving this notice for more and more commonly accessed websites. I get the message if I have https only selected or not selected. Currently receiving for Lowes, Home Depot, American Airlines and more. I can go to a Firefox 135.0.1 browser on a separate desktop accessing the internet through the same router and do not have issues. I suspect I have been upgraded by Mozilla into a less functional browser version for whatever reason that Mozilla does this.

In the last few weeks, Thunderbird seems to crash randomly multiple times per day. Every time it crashes, I get a popup that apparently sends some kind of report to Mozilla as soon as I click the "Quit Thunderbird" button. I am on version 140.1.1esr of Thunderbird on a Windows 11 computer with 32GB of Ram and the latest version of Windows. If anybody knows what might be causing this (since I don't see any error messages), I'd sure appreciate it.

Hi!

I am not sure how to address this. I like to have my pinned tabs always in view whenever possible. So when I click on another tab outside the tab, I'll utilize that and then go back home. While in other tabs, I may utilize the extension tab manager plus for Firefox. The last few days I'll click on a tab on need. It opens the page, but does not show the tab at the top of the screen. What is happening and how do I fix this?

Thanks.

Running Firefox 141.0.2 on Mac Sequoia 15.6.

I have frequently used firefox to reach this local server until today. The server itself currently responds to pings, traceroute works. I can ssh to the server. I can access an SMB share on the server. All of these were tested after I ran across this issue. The server doesn't support HTTPS.

Today when I attempted to reach the server in Firefox. This time I got a popup (from Firefox, I presume) asking if I wanted to add this server to some sort of list. As I am still largely human, I didn't really read the popup, and just selected "No". And now I can't reach the server (from Firefox, that is).

So, how do add this server to Firefox's whatever list? The "Server not found" message is, as always, not even slightly helpful.

Thanks in advance.

I am experiencing an issue in Thunderbird where the display name in the message list does not update correctly for certain email addresses.

Environment

Thunderbird version: (e.g., 115.12.1 64bit)

OS: Windows 10 Pro 64bit (version ...)

Symptoms

I deleted the entire address book (abook.sqlite, history.sqlite, etc.), so it is completely empty.

However, in the Sent or Inbox folder, some addresses still show the old display name that I previously assigned.

When I right-click the address → "Add to Address Book", the new display name is not applied for these specific addresses.

Other addresses work fine under the same conditions.

Tried

Deleted cache files (global-messages-db.sqlite, .msf, panacea.dat)

Cleared Collected Addresses

Created a new profile and tested again

Restored profile from one week ago

Result

In all cases, some addresses still do not update the display name.

Question

Is this a known Thunderbird bug?

Besides clearing caches and history, is there any way to control the priority of display name shown in the message list?
