Thunderbird Support Forum

As a longtime user and a regular subscriber to Mozilla, I can’t get access to Thunderbird. Reason is that I had to repair the hard drive and now I am locked out. I am unable to insert a master password because I never had one. Reason being that I have used Thunderbird for years and years before that was required. To say I am frustrated is an understatement. None of your automated advice has a remedy. Should I install a new version of Thunderbird and begin afresh? John Cotterell ( an Australian supporter of your project)

Hello, For some reason, over the past couple of months I have been searching for varied emails and they are missing! At one point, I found that some had been put in an archive folder (that I did NOT set up) and they were recent emails. I removed them from the folder, placed them back in the regular inbox and deleted that folder. When I could not find another very important series of emails today, after searching numerous ways, I looked in the server and missing emails are there. I did look at a number of email threads where other people reported similar problems... but couldn't figure out what applied to my situation and how to fix this. To show a specific example, I attached two images ... the first is my Thunderbird email account that shows one Email only on Feb 18, 2024. The Juno server image shows 7 emails on that same date, four which were important contracts that were sent to me. Can you please help me locate and retrieve these and other missing emails? Thank you very much. Ms Randy Rosette

Hello,

I'm using Thunderbird for my private and company e-mails (different companies). I need to pay close attention to selecting the right names as the auto suggest for recipients isn't using the context of the current account. Is there a plugin or setting I've missed that considers the context of composing a mail and priorities collected e-mails from the respective account or recent conversations for example? Good example is the Gmail auto complete, that has a good suggestion ranking.

Best I could find was options to sync with Google Mail contacts, but that would require to maintain a list of contacts in Google Mail, which I don't do.

Best, Elmar

Already invested time creating some html code for email signature on thunderbird. Wanted to create something prepared for dark modes on IOS. Everything was fine until I detected on IOS (dark mode)some white rectangles outside my email signature code. It´s a problem that I cannot solve because it´s outside my code, and I´m wondering if you are already aware of this issue.

In case you want to test my code on a Thunderbird HTML email signature and see the result on an iPhone (dar mode), you can get it here: https://codeshare.io/dekBnR

je n'arrive pas à envoyer des mails avec ma messagerie sur Thunderbird, mais j'en reçois. L'icone en forme de cadenas est barré de rouge, cela m'affiche qu'il y a un problème avec le chiffrement des messages. Puis, que la connexion au serveur sortant SMTP free.fr a expiré ...

Que puis-je faire ?,?

Since applying update 115.10.0, Thunderbird will not close correctly and will not relaunch until task is ended in task Manager. This is true on a windows 7 PC and windows 10.

I have been struggling with this problem for about 6 months now and no-one I've asked has been able to help me. Even my computer guru failed me! I think it was after an update about last June when I started having this problem An nothing I've tried has had any effect. I had a Geek Squad guy on the phone with me for about 45 minutes to no effect. He said he'd never seen the problem before. I have business emails on that account so I don't want to risk losing them. Can anyone help me please? Christine

I use Thunderbird to get my COX and Gmail emails. When Cox moves to Yahoo what needs to be changed in Thunderbird to get my emails? Below is what came to me from Cox: The countdown has begun and your Cox email will transition to Yahoo Mail in about a month. Rest assured, knowing you'll keep using your same Cox.net email address, messages, folders, contacts and calendar!

After the move, Yahoo Mail will become your email provider and Cox will no longer manage or support your email services. Yahoo Mail will make sure you stay connected by protecting your inbox with 2-Step Verification, Account Recovery Email and Phone Number, 1,000 GB of free storage and more.

Since the latest upgrade to 115.10.1 (64-bit) I have an issue about running Thunderbird.

From a clean Windows 11 start up it is OK but then if I then Exit and then try to run the bird again it does not start.

Digging around I discovered using Task Manager, a number of Thunderbird processes run after I had Exited. See attached.

Any thoughts?

I created my email signature and saved it as an HTML file. When I add it in my account settings, it displays the logo I have as a blank box. It also adds extra spacing in between each line. How do I get it to display the way I saved it?

Some email clients allow the user to change the subject line on an incomng email. I had a client where I could edit the subject line and then store the email in another directory. Changing the subject line allowed for a better way to find the email later on as one can change the text to something understandable and easier to seach for. Can this be done in Thunderbird or is this for the wish list? Cheers Bob

I can receive emails to my (protonmail.com server) email account on Thunderbird. But I cannot send emails. This is the error message. "Sending of the message failed. An error occurred while sending mail. The mail server responded: Error: no such user. Please check the message and try again."

Thank you for your help!

Hello, I got a tale of two computers with Thunderbird on both. First, I will start with my HP Laptop, its my primary computer due to its speed. I went to check my emails this morning. I double click on the TBird icon on my desktop. It does not open. Waited a few seconds, tried again and again. Finally, a folder containing pictures opened up. Then, I went to open FireFox, and that same folder with pictures opened. I tried this like five times and the same thing happened. Then I got to thinkin, when I went to shut it down the other day, it said "update and shut down", so I did. Now that I remembered the update, I decided to go back in time to when the laptop was running real good. So I did that recovery, in doing so, it wiped out some of the applications I had on my computer, such as FoxFire, Thunderbird, Adobe, HP printer, CCleaner, and probably others that I seldom used. Somehow, I got to the point where I reinstalled Thunderbird. The only thing is, it would not let me in. When double clicking on the icon, it took me to a page that just wanted my name, email address and password. I enter the info, that page stayed open and added a few more items to the page, such as IMAP and POP3 stuff. IMAP was already selected by Tbird. I then had the option to click "done" . In doing that, it said "Unable to log into server. Probably wrong configuration, username or password" So there's that. Cannot even see the email program. Second part of the mystery, I have an old Gateway desktop. Its slower than slow. I only use it in emergencies, as the above scenario. I fire it up, wait about 5 minutes before I open Thunderbird on that. Guess what, it wants a password. Whats different about this deal is that the email opens, and I can see all my previous emails, but cannot receive or send. I have no Idea whats going on, unless its my deceased wife coming back to haunt me...I don't know.

Good afternoon,

I recently installed Thunderbird, and it worked fine for a little while. More recently, I have been having problems with it. One of them I was able to fix after some research and trial-and-error (which was Thunderbird not letting me log into my Comcast/Xfinity email account), but this second issue is confusing. I had to remove the account to get back into it (during the first issue), so I'm guessing that must have caused this (second) problem?

When I went to check my filters/rules today (since I receive significant amounts of spam), I was shocked to see that my filters list was empty (I had about 30 or so filters in place before the first issue occurred). I'm guessing there's no way for me to get these back, and so I'll have to manually reinstate each filter "by hand"?

If there is any way to do this more easily, I would greatly appreciate it. Thank you in advance for your time!!

I have tried many times to add a third email (Gmail account) to my Thunderbird email application. I successfully added both a Comcast and Outlook email account, but Gmail won't install. I'm using Windows 11 on a Surface Pro 8 laptop.

Thunderbird will no longer save sent emails to my SENT folder. I get an error message when I send an e-mail saying, "Your message was sent but a copy was not placed in our sent folder(Sent) due to network or file access errors. You can retry or save the message locally to Local Folders/Sent-using my email address. Cox Communications is my ISP and they say the problem is not theirs.

Title. Thunderbird is a really cool client but it's pretty slow. I blame that on the thousands upon thousands of emails that my hotmail and gmail each hold. I don't necessarily want to delete these emails, but I have seldom a reason to have any email older than 2 months in my thunderbird client slowing and crashing the program whenever I want to combine inboxes.

To this end I went to "Synchronization & Storage" and told it to "Synchronize the most recent 2 months" but it didn't delete the huge cluster of older emails. The next option is to tell TB to delete these emails in the same menu but as I understand it that would also delete them in the server, which I don't want to do for posteriority.

What do I do?
