Edit address book entry displays only DELETE and CANCEL at the bottom of the edited entry. The rightmost border may be obscured as the display does not allow for scroll.

It was working fine on the new computer until yesterday. Now I get a pop-up box that says: ' Unable to connect The connection was refused when attempting to contact localhost.

The site could be temporarily unavailable or too busy. Try again in a few moments.

If you are unable to load any pages, check your computer's network connection. If your computer or network is protected by a firewall or proxy, make sure Thunderbird is permitted to access the web.

Hi everyone!

I'm trying to log into my email account on the domain example.com via SMTP. The email account is with yandex.ru. When I try to authenticate, it says the SMTP password is incorrect. I decided to try through Outlook, and it worked. What could be the issue?

Despite my marking messages several times as NOT spam, Thunderbird keeps on and on RE-marking them as spam. And the mails are coming from one of my own addresses, and they ARE in my address book!!!!!

There seems no way that I can stop the beast from misbehaving.

Hello, I can't receive any of my e-mails. I can send e-mails out now. Plus I can put in my password to log into my e-mail. This has been a headache for me, I have been with Thunder Bird for years.

I also get a boxes that says : Unable to write the email to the mailbox. It says to make sure the file system allows me to write privileges, and I have enough disk space to copy the mailbox. I have enough space on my computer system and all. Another box that says my e-mail is being processed. Please wait until processing is complete to get messages. I did e-mail you yesterday on these issues. As I said I can e-mail messages out now also log into my e-mail with my password. Thanks, Chris

Subject: Persistent Column and Folder Layout Issues — Not Being Saved Between Sessions

This is a follow-up to my previous support requests regarding two ongoing problems that significantly impact daily usability.

Column Settings I manage multiple accounts, and my preferred column layout is: Starred, Read Status, Attachment, Subject, From, and Date/Time. I do not use Threads, Correspondents, or Spam Status columns. Despite setting these preferences repeatedly, Thunderbird fails to retain them. Every day I must spend time reconfiguring columns across some or all of my accounts — the state varies unpredictably from one session to the next. This is a persistent, daily frustration that costs meaningful time. Most other major email clients save and reliably maintain column preferences. I'd expect Thunderbird to do the same.

Folder Panel Layout Two problems occur regularly when Thunderbird loads:

Folder order — Standard system folders (Inbox, Sent, Drafts, All Mail, Trash, Spam) should appear at the top of each account. Instead, Sent, All Mail, Trash, and/or Spam are frequently scattered among custom folders, with no apparent consistency.

Folder expansion — Most or all folders load in an expanded state, exposing every nested sub-folder regardless of whether they contain unread mail. This creates unnecessary visual clutter and requires manual collapsing each session.

Again, this behavior is uncommon in other widely-used email clients. Summary These are not one-time glitches — they recur daily and represent a significant usability gap. I'd appreciate confirmation that these are known issues being tracked, or guidance on a reliable fix. Reformatting the interface every morning is not a reasonable expectation for users.

Neither my wife nor I can access email on our respective PCs. This has been the case for four weeks. We can access email by our Android phones, but we really want to use our PCs. I've tried to resolve the problem and failed. Previous to this failure, I had an account with BT but this was transferred to EE. When I attempt to log in to my mail account, I receive the message "Could not connect ... :the connection was refused". I can also add is that in my Account settings, Outgoing Mail server I see a message "Connection to server mail.btinternet.com:465 failed."

As the topic says, the message list turned from the usual dark-mode look, to a full black background after updating to 151.0.

Was this an intentional change? How can I revert it?

Hi,

I've just updated my Thunderbird for Windows to 151 and I got this nasty surprise (this is why I hate updates these days).

The message list in dark mode, in a table view, now has this awful pitch black background instead of the normal dark brown as it used to have. It looks OK in cards mode, but I don't like cards mode.

I certainly hope this is a bug and not by design. Can this be fixed, please? It looks terrible, it's hard to look at, like old Windows 10 dark mode or some high contrast accessibility mode.

Thank you!

Recently it's a daily occurrence that I must enter the password for my SMTP server. I always check "Use Password Manager to remember this password" but it doesn't help. The next day I'll have to go through this again.

I power on my machine multiple times each day, and I use Thunderbird each time. It doesn't happen each time. It seems to happen only the first time I use Thunderbird each day. This is new behavior. Before it would happen now and then, now it's daily.

I don't have a Primary Password. No need for it.

If you need to see the message I can send it to you, but I'm not attaching it right now because it shows my email address and the smtp destination. Maybe I'm being too careful.

When clicking the "cloud icon" ("get all new messages") I would expect it to check all accounts. But it only check the account that is currently displayed (not the others). Is this a known bug? Is there a setting for this?

Lorsque j'essaie d'ajouter un nouveau compte, la configuration est trouvé dans la base de données des FAI de Mozilla, je clic sur "continuer", dans la fenêtre Popup j'autorise Thunderbird a accéder à mes informations, ensuite j'ai le message "erreur d'authentification". Pourtant mon mot de passe est correcte.

I had to reinstall everything after a Windows glitch. I always liked to have Thunderbird show a list of my emails with a window below to show the content of emails I selected in the list. But now I can't find anything in settings to allow me to do that.

A substantial portion of email spam that I receive has a couple of characteristics: - the subject line includes "Sonic", and - the sender is plainly not Sonic.

For example:

Return-Path: <live1@tomokawasaki.or.jp> Received: from tomokawasaki.or.jp (tomokawasaki.or.jp [122.1.223.161]) by mwb-sdgw-mts-005c1.ocn.ad.jp (Postfix) with ESMTP id 063B61400008F for <ronks@sonic.net>; Sun, 19 Jul 2026 07:07:06 +0900 (JST) From: =?UTF-8?B?U29uaWMg0JLRlmxs0ZbQv2c=?= <live1@tomokawasaki.or.jp> (From translates to "Sonic Billing" here; in other spam it is cleartext) Subject: Automatic Payment Unsuccessful To: <ronks@sonic.net>

I am wondering if it is possible to construct a filter that says basically: If Subject includes Sonic AND From does not include Sonic Then Send to Trash (or mark as spam or whatever)

Can this be done?

Been using outlook since 2000, I am tyrin to cut the umbilial cord to outlook as it is craper each year that passes.

Can i have more than 1 sig as i use maybe 10 different sigs for different reasons?

I see a use file do i get to choose a differt file when inserting sig or am i stuck with one and have to manualy change file or copy from somewhere else.

Once i get Thinder runnin i wil be happy to support on a monthly basis but i need to se if ti will suffice.

Hi

I have set up Thunderbird with a Zimbra mail serveur (Zimbra serveur 10.1.10_GA_4785) using the EWS new feature of Thunderbird.

I can setup the EWS account. The test of the secured connection to the server is returned valid. But in the mailbox, the list of folder is empty, and I see no email. Interestingly, I can successfully send email from this thunderbird using the exchange server as sending server.

To resume, no emails are received, but sending emails works.

So, I check the request to the exchange server when starting a synchronization : Here the result : Request : <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:t="http://schemas.microsoft.com/exchange/services/2006/types"><soap:Header><t:RequestServerVersion Version="Exchange2010_SP2"/></soap:Header><soap:Body><GetFolder xmlns="http://schemas.microsoft.com/exchange/services/2006/messages"><FolderShape><t:BaseShape>IdOnly</t:BaseShape></FolderShape><FolderIds><t:DistinguishedFolderId Id="msgfolderroot"/><t:DistinguishedFolderId Id="inbox"/><t:DistinguishedFolderId Id="deleteditems"/><t:DistinguishedFolderId Id="drafts"/><t:DistinguishedFolderId Id="outbox"/><t:DistinguishedFolderId Id="sentitems"/><t:DistinguishedFolderId Id="junkemail"/><t:DistinguishedFolderId Id="archive"/></FolderIds></GetFolder></soap:Body></soap:Envelope>

Anyone successfully used the new EWS feature with Zimbra server ?

PS : I confirm the EWS connection with the Zimbra serveur by successfully using EWS on Outlook for android.

I use Thunderbird when Postbox acquired another. I am using 2 computers - desktop, old (10+ years), still Windows 10, and 2 two emails; new laptop (traveling), Windows 11. I download Thunderbird and set up my accounts - gmail.com and twc.com. Troubles with gmail.com, but finally I set up. However, I can't set up twc.com. I like twc.com-- no reason. (Time Warner Cable (twc) bought Spectrum. ) I can login twc.com webmail. Not Thunderbird. I looked carefully set up, Thunderbird searched, found "Host: mobile.charter.net" (Huh?, , continue, enter my password - "Error: ---". I removed VPN Windows 11, no difference. (Curios, my laptop and Firefox, my bank rejected connection. My desktop and Firefox still connects! I dread the day must update.)

I am look forward yours reply. (Maybe Spectrum is searching to dump twc.com.) Jeremy Fields P.S. I wrote with my desktop - windows 10 -, my new laptop (windows 11) is problems

Today when I started Thunderbird two of my email accounts are Highlighted in RED with a RED Triangle at the end of the email address.

Both accounts are from Spectrum. My other email accounts from another provider are OKAY.

I am not able to retrieve or send emails on these two accounts. I can get my emails from both accounts when I use Spectrum Webmail. So it looks like the account information is correct.

How do I fix this?

I don't use Archives or Templates. There is no folder on my servers that correspond to these and they are not subscribed in my IMAP settings.

They don't appear in the per-account view. But they somehow appear in the unified folder view.

I am not able to figure out how to make them disappear.

Help.
