I have used Thunderbird since vs 2.0. I currently have 7 active email accounts, but have had up to 12 on my Windows platform running with no problems. Installed: Thunderbird vs 140.3.1esr Windows 10

I have recently had problems with the password entry for three of the accounts which use verizon.net, managed by AOL.

When sending a message on that email system, I often have to enter the outgoing server password manually. I have changed password on all three verizon.net email accounts, and for a few days email sends worked fine. But now, I am back to having to enter the password in the pop-up box when sending mail.

Any reason why this problem occurs after the system has operated fine for months/years. I don't see this problem with my other accounts using different mail servers.

I try to send email from an address I used to and I have this message :"Username and email address belong to two different users.". I don't understand why ?

I installed the latest version of Thunderbird on my new Windows 11 PC, and when I try to save an attachment without opening it, it doesn't save. I need to open it and then I can save.

Dear Concern,

I have configured [edited] @cogdual.com as the primary mailbox. I am trying to add few more email ids to the same inbox which i am not able to. When i try to add the mail in the Add option, it is buffering and not process forward

Not resolve even after multiple efforts. Please guide

Regards,

Today I am not able to send emails on my phone. Even a simple test msg is met with an alert and an email in the outbox. I have restarted the phone, and also cleared Thunderbird app cache and forced stop. I still get it. I sent emails last night no problem. I am able to send emails using domain webmail and desktop Thunderbird application. This is only on mobile android version 14. Thunderbird 11.1

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!!

Thunderbird : 141.0 (64-bit)

So, I've no idea why, but my Today Pane is now only displaying a single event per day (see image).

For example, Monday 20th October has multiple events, but these don't show.

Is there a fix for this?

I have McAfee Total Security installed & up to date on my PC.

3 times today, the AV reported files being generated by email contain malicious links or attachments?

e.g. in AppData\Local\Temp newmsg-46 newmsg-73

Thunderbird 128.13.0esr was installed. I have just updated to 128.14.0esr, then immediately prompted to install140.4.0esr?

Was this a known issue?

Thanks

Hi, I'm trying to set up a gmail mail account in Thunderbird on a Mac. The email address is active on Gmail. On Thunderbird I click for a new account. I type in my name and mail address and get an auto configuration. Then I get a window to sign in to continue to Mozilla Thunderbird Email. I enter the new email address. Instead of getting a password request, I get a Google message saying wrongly configured request.

So I thought maybe I should create a new Mozilla account with this email address, and I got a message saying something went wrong.

I've tried several times. What's the secret.

I am not sure if this is the correct place to ask my question. Apologies if you think it should be somewhere else in Thunderbird Help.

My old W10 machine crashed in September. I bought a W11 machine in October.

A colleague managed to rescue all my data from the W10 to a HDD.

I installed Thunderbird 143.0.1 to the W11 machine. On running the program it found me and my emails. I hoped it would find my wife's emails too. But no luck so far. Both domain names are the same. I've tried adding the details I have for my wife's email as a new account, but the program goes on and on looking with no result, and no end. I have to unplug the power cord to end it.

I've followed advice from the help pages to Find and restore my Profile without opening Thunderbird. In the process I've deleted the Profile on the W11 install, and substituted the Profile from the W10 install. It was around 8GB. So I assumed that Local Folders and my wife's details would show. Neither of these things occur. My account is shown together with recent emails.

What is happening? How can I get my wife's email account to show? How can I find my archive of emails in Local Folders? Any help gratefully accepted. Thunderbird 101 maybe?

Under Inbox | Trash in my TBird account is a structure

2019
  subfoldername
     sub-subfoldername

in italics, in gray letters. When I try to delete it, I see "The server replied [Nonexistent]" and the structure disappears; until I close and reopen TBird, and there it is again. When I select "Empty trash" I get no error message and the structure disappears; but it reappears on reopening TBird. How can I make it gone gone gone?

Hello, I hope I'm in the right subforum. I have the following problem.

In my system settings, Opera is set as the default browser, using the command "opera %U --lang=de."

Unfortunately (despite the system-wide setting), when I want to open an https link, Thunderbird still asks me which application I want to use. Unfortunately, as is usually the case, I can't select one from the application menu (where the corresponding command is stored in Opera). Instead, I have to search for and specify the application in the /usr/bin folder. This logically opens the link with the "opera" command and not with the "--lang=de" option. However, Thunderbird doesn't accept a desktop file under "Open with...", where you could add the option.

I've now created a shell file with the following content:

1. ! /bin/bash

opera %U --lang=de

This opens the browser as desired when I click the link, but only with the home page; the link isn't passed.

My question is, how would the command in the shell file need to be changed to open the link, or is there any way to get Thunderbird to open links with the command "opera %U --lang=de"?

Thank you.

My questions are:

i was about to add another account to TB and checked for cves first and saw this:  CVE-2025-11715. 

Ubunut 22.04 is affected by it but there is no way to update my installed version to a stable release in the software centre.s my current 140.3.1esr snap download of thunderbird on ubuntu software centre unsafe and should i remove account and uninstall it immediately?

Is there a safer snap version to use? I see 140.4.oesr-1 is available in the drop down menu on the mozilla thunderbird snap page in software centre but its only latest/candidate which i think means not yet stable? Is this a safe choice?

Clicking on the 140.4. version from snap doesnt update but requires a new install. Is the best idea to go ahead and install this 140.4 candidate version rather than continuing with 140.3.1? Should i just hold off using thunderbird until my installation recieves an update? I do really need to use it so this is a last resort.

i have autism and stuggle with processing information and worry about installing the wrong thing. i thought the ubuntu snapstore as verified by canonical would be stable and secure. I am nervous of downloading from browser in case i download a fake site or mess it up installing and I dont know how I would be sure I had an authentic version. Im not great at using the terminal and knowing if ive input correctly either. It seems that apt would just fetch snap version anyway. if downloading from site was the best way to procees, do i need to uninstall snap first and how can I check its not a corrupted file?

Please can I get help on the best way to proceed to use a version of thunderbird that is definitly safe to use and add accounts to?

Also could my passwords and emails already be compromised by using 140.3.1esr and should i stop using it immediately? would an update be enough to remove the threats? 

Thanks

On my Framework 13, Thunderbird has stopped. Message reads Oups! We're sorry, it looks like thunderbird crashed. Please contact the developer if you want to report the issue. At 85, I'm anything but a nerd. Could someone please help me in simple, everyday terms? I have a lot of incoming and outgoing emails, and am completely stuck. Thank you.

Can't send to myself, can't receive to myself. Dates on display completely out of order and no current emails to inbox.

Thunderbird seems corrupted.

I am on the brink of re-installing Thunderbird.

I logged into my email account and almost 3 months of my most recent emails had disappeared. I don't know what happened. They were there the last time I checked my email about 5-10 minutes earlier. I've looked in other folders but they aren't there either. Aso tried repairing the folder with no success. Is there a way to recover these emails? I've been trouble shooting / googling this all afternoon and kept seeing reference to a recovery tool. Is this something already on Thunderbird or software I need to purchase? I really want to know if there is a way to recover the lost emails and how to do it. Thanks.
