Thunderbird Community Forum

Hello, I have enabled the Thunderbird dark mode. My expectation was that all messages in the message list are displayed in white on a dark background.

Unfortunately, the message list often uses a black font on a dark background.

I changed the color in the message pane using settings --> Colour

I followed the instructions/workarounds here for using dark theme, including reset and troubleshoot mode. https://support.mozilla.org/sv/questions/1439922

But it did not help. Maybe you guys can help.

Regards George

Since the most recent Thunderbird update, multiple Inboxes duplicating old emails have accumulated. Please see the attached jpg screenshot. How can this be remedied? Thank you in advance. J. Collier

Hi everyone,

I’m having some trouble with Thunderbird and could use some guidance. I’ve been trying to install the latest version, but I keep running into issues. The installation either fails midway or gives an error message I can’t figure out.

Also, for the times when I’ve managed to install Thunderbird, I’ve noticed that updates don’t seem to apply properly. The program either doesn’t update automatically or prompts me to download the full installer again.

Could someone explain the proper steps for installing Thunderbird and ensuring updates are applied correctly? Are there any common pitfalls or settings I should check to avoid these issues?

Any help would be greatly appreciated!

Thanks!

For a better viewing I want to create new subfolders in each account, but since last updates it isn't possible. I can choose, but no new button for the name appeares. What have I to do, that it will be possible? Thanks Achim Kleiß

As of today, I can't access attachments. Emails in the message list pane correctly show the paperclip icon but when I open the message, there is no attachment file name displayed. If I forward the message, the attachment appears and is forwarded correctly but if I click on the attachment name in the forwarding message pane, it disappears.

Note that this problem applies to all folders, including Personal folders and their subfolders, not just Inbox.

I am having PC stability problems and it may be that Thunderbird was caught in a freeze or crash. In any case, I really need a solution. Can you help?

I cannot add folders or sub-folders under the inbox in one of my 4 accounts I use with Thunderbird. Have I hit a limit? I need to file in a specific way for our book-keeper who shares one of the email accounts. I was happily adding the sub-folders when I realised the first ones added were disappearing, then it was refusing to allow me to add any new folders OR sub-folders.

Please help brains trust!

Since 30 November 2024, I have been unable to receive emails. I get the message " Connection to server mail.******** was interrupted. Can still send emails. Using the latest version, Thunderbird 115.16.3 with Windows 7 64bit computer. I have turned off windows firewall to no avail. Able to read mails through webmail.

How do I insert a merge field (person name) then followed by (mobile phone) in a mail to my address book that is already {{Email}} in the address line

thank you

I have an email account with Spectrum. Recently, I linked my Thunderbird client (128.5.5 esr 64-bit) with Gmail and now find that my Thunderbird inbox has been completely put under the control of Gmail. Email still arrives at the Thunderbird Inbox but, if not acted on quickly, is removed to my Gmail account, leaving the Inbox empty. It is also removed from the Spectrum server. I spoke with Spectrum and they confirmed that they are not forwarding the email and that the solution to the problem is with the settings in Thunderbird or Gmail. I would like to stop all forwarding of my email from Thunderbird to Gmail. I’ve looked hard but not been able to find anyway to do this either in Gmail or Thunderbird. Please advise. Thank you.

I'm trying to migrate from an old OS/2 and Thunderbird 38 system to a new Red Hat Linux and Thunderbird 128 system. I think I've copied all the server settings faithfully, but when I try to fetch mail, nothing happens. If I open the developer tools->error console, it says:

pop3.server1.3: SecurityError: a SecurityProtocol error occurred Pop3Client.sys.mjs:380:18

   _onError resource:///modules/Pop3Client.sys.mjs:380

pop3.server1.3: SecurityError info: SSL_ERROR_UNRECOGNIZED_NAME_ALERT Pop3Client.sys.mjs:422:20

   _onError resource:///modules/Pop3Client.sys.mjs:422

I worked with an IT guy to help me transfer information from Carbonite back to Thunderbird. I can see all the files download to my computer but can't get them and the address book to update. Does anyone know someone who specializes in helping people with Thunderbird issues?

I have a valid x.509 certificate and am able to send S/MIME signed emails via Thunderbird 128.5.1esr (64-bit) [Windows 10.0.22631.4460).

The private key is stored on a Yubikey. However, the certifying authorities are in the Thunderbird Authorities.

I can send S/MIME signed emails.

Viewing the received email in Gmail (web) correctly shows that email is signed, verified by a known issuer, and provides links to the certificates.

Viewing the same received email in Thunderbird only shows the S/MIME badge/icon when the Yubikey is connected.

Is this intentional behavior? Why doesn't Thunderbird show the S/MIME badge?

The junk function does not work very well. It removes perhaps 50 per cent of junk email. Otherwise, I have to go through email every day and manually remove the junk. I've checked settings and there doesn't seem to be any other way to handle it.

Hello,

How do I create a new account with Thunderbird? (The support article hasn't been updated in 3 years.) Is it still possible to create a new account with Mozilla, or do I need to create an email account with a third party such as Mailfence and then log in? Should I just use Seamonkey instead? Please advise. I would like to integrate my browser and email. Thank you.

I created two new email accounts (ex: info@newemail.com). I can sent from them just fine, but when I send TO them the emails are received in a separate set of folders under the name of that email address. How do I get those emails to appear in the Inbox under Local Folders instead of in the Inbox under info@newemail.com.

I've set its Copies & Folders to the same as my other email addresses where received emails do appear in the Inbox under Local Folders.

The global search in TB is completely defective. I am now running 128.2.0esr and hoped that update might fix it. It hasn't. I just wonder, are there any older or non ESR versions I can downgrade/move to, where the search is fully functional?

Since the last thunderbird update, my emails are NOT downloading properly. They download to my android, but they do not download to my PC what should I do 'Thank you.

Plus, I am unable to send email out from my android, but can send from my PC.

PS: my android is working with my gmail account.

Thank you for supporting lometto@usit.net
