Thunderbird Support Forum

When I restart Mozilla Thunderbird, my S/MIME certificate preferences under Account Settings seem to break.

When I initially select a certificate, both the common name/certificate name and the certificate fingerprint appear in the interface (see Working Settings.png). However, after restarting Thunderbird, only the common name/certificate name appears in the interface, and I cannot use S/MIME to sign messages (see Broken Settings.png). When I attempt to do so, I receive the following error message:

Send Message Error Sending of the message failed. You specified that this message should be digitally signed, but the application either failed to find the signing certificate specified in your Mail & Newsgroup Account Settings, or the certificate has expired.

To be clear, Thunderbird has no problem finding and using the certificate right after I set it—the problem only appears when I restart Thunderbird and the appearance of the certificate in the settings changes. The certificate does not expire until April 2025, so this is not the issue. The issue also occurs with another account using a different certificate that is also unexpired.

I am using Thunderbird 115.12.2 (64-bit ESR) on MacOS with Apple Silicon.

My e-mails fail to be delivered to my inbox immediately. They are held up somehow and then suddenly appear days later as a batch of them as though they have been held in a storage box.

Hello,

My friend recently encountered an issue where he can no longer send email messages. Suddenly, all the buttons in the "Message" tab, except for "Create," became disabled. Additionally, the "Send" related buttons in the message creation window have disappeared.

I attempted to restore these buttons using Alt -> Toolbox, as suggested by similar questions. While the buttons do reappear in the toolbox view, they vanish again once I exit that view. All outgoing servers are configured correctly, and this setup has worked for several years without any problems. It seems that something is now blocking the ability to send emails.

We also tried updating and reinstalling the Thunderbird client, but nothing has resolved the issue.

Attached, you will find images of the disabled menus and proof of the correctly configured outgoing servers. Apologies for the software being in Russian; I hope it's still clear which buttons are disabled since the interface layout is the same.

Any suggestions would be highly appreciated! Thank you.

Hi,

I am running thunderbird-115.12.2-1 and Arch Linux and have the following Problem:

- I am using Unified Folders - Online search is disabled - If I change the view in any Unified Folder with more than 1 source folder to grouped by Thunderbird freezes and sometimes crashes - It does not matter what the sort by value is - Any time I switch from a not grouped by unified folder back to grouped by Thunderbird freezes and crashes sometimes again - The length of the freeze depends on the numbers of source folders for the unified folder. E.g. for my Inbox with 11 source folders between 5 and 10 minutes

I already tried - disable all addons - clear the disk cache - set mail.server.default.use_condstore to true - delete global-messages-db.sqlite

Right now the group by feature is not usable for me but makes it so much more clearer that I don't want to miss it.

Can you help me ?

I get the pop up that includes Add Security Exception

 You are about to override how Thunderbird identifies this site.

Legitimate banks, stores, and other public sites will not ask You to do this. Location:

This site attempts to identify itself with invalid Information. Unknown Identity The certificate is not trusted because it hasn’t been verified as issued by a trusted authority using a secure signature.

I am in Australia and Optus is my email provider. They have checked all is working at their end and suggest I contact Thunderbird which is why I am here.

Thanking you for trying to help

When I launched Thunderbird today, it would not connect to one mailserver: imap.mailfence.com. At the same time, Thunderbird said to restart to update to 115.2.2. After updating, it still refuses to connect. There is nothing wrong with Mailfence and I do not find anything wrong with the configuration settings in Thunderbird. I even tried to set up my Mailfence email account again but it failed because it could not connect. Ideas? Thank you.

"Sending of password for user joebernard@verizon.net did not succeed. Mail server pop.verizon.net responded: [SYS/TEMP] Server error - Please try again later"

^^This message comes up every time I try to send an email. It can be received outside of Thunderbird and to other addresses.

Dear

Subject to the following mail addresses: gunter.peeters@scarlet.be

We keep getting the following message when sending emails. An error occurred while sending email. The mail server replied: ip 213.49.30.104 blocked for relaying spam http://www.scarlet.be/pm/?e=f53&s=r&p=213.49.30.104. Please check if your email address is set correctly in your account settings and try again.

We are able to receive emails.

Is it possible to check this out?

Thanks in advance!

Kind regards Gunter Peeters

Hi everyone, My Thunderbird yesterday - without doing any unusual chances that know of - went weird. Whenever I open the programme now it shows a completely different interface and I can't navigate back in any way to the usual calendar, email, contacts. It also seems to be frozen, because when I click settings it doesn't open any window. I have attached a screenshot of how it looks now.

Could anyone help me out on how to get back to regular Thunderbird? I am also a bit worried of losing all my contacts / calendar.

Let me know if there's more info I can give from my end. Any help very much appreciated.

I cannot send or receive messages on my Thunderbird a/c. I Believe I have to firstly update my email password from my supplier (Spark New Zealand) but to date I have been unable to do this. When I tried to do this on line Thunderbird indicated they did not recognize my email account at all. What should I do?

Thunderbird 115.12.1 (64-bit) on Linux Debian 12, I have several accounts in a panel on the left. When the accounts are collapsed, they unexpectedly expand and make it difficult to know which account's email I'm reading on the right.

How do I control that behavior, please?

I keep getting "can't connect" message and I have to enter my password for outgoing mail. Incoming comes through no problem. How can I get Thunderbird to remember my provider password for outgoing? They obviously already have it for incoming.

Regularly the messages in some subfolders are doubled. I don't know why or how it was triggered. It is very annoying, because some subfolders contain a lot of messages. Since I don't know how to get rid of this double messages, except by deleting them by hand one at the time, it is a very time consuming matter. I tried repairing the folder, but that didn't work. I already have had a folder where all messages were doubled several times. So every message was there six, seven, or eight times! Is there somebody with an explanation and - preferably - a solution to prevent this?

It seems as the interface thinks the window containing Thunderbird is longer than it actually is. The bottom part of the interface is missing and there's no scroll bar. This is most apparent to me in the Address book, where part of the fields is invisible, as are the Cancel/Save buttons. When I start Thunderbird, that bottom part of the interface would appear for about a second and then disappear. Resizing the window doesn't help.

When I start Thunderbird in Troubleshooting mode, the interface works fine, but "Reset toolbars and controls" and "Disable all add-ons" doesn't fixt the issue.

It might have started when I connected a secondary monitor, positioned above the primary. I thought disconnecting that monitor fixed it, but I since reconnected it and the issue now won't go away except when in Troubleshoot Mode.

I set up a new Windows 11 PC (64-bit) about 2 months ago, and installed Thunderbird Supernova. I allowed MTS to choose all the settings and everything was working fine until about 3 weeks ago I am now running version 115.11.1 (64-bit). I noticed that many messages I recieve at scheduled times every day were not appearing in my MTS message list until sevveral hours (a few actually took 3 days) after their normal delivery times. Checking with the senders revealed no change to the time they were sent. Looking at the messages when they appeared showed that they WERE received on time. Logging into the web interfaces for Gmail and Comcast/XFINITY email revealed that the messages were arriving on time. The only logical conclusion is that MTS has a problem in its IMAP protocol implementation that does not recognize new/unread messages as such, and therefore does not retrieve them. I am legally blind, and up to this point, mTS is the only fully accessible, easy-to-keyboard-navigate email program.

Can't use Gmail account anymore have cleared cookie's and caches removed permissions and account from Google and TB uninstalled then reinstalled then add TB account worked for 2 minutes then got the same error also some emails load while others are just a blank screen all windows 10 and TB updates are current Have attached error we are receiving anything else please just ask Any help appreciated

Good morning. I have been unable to receive e-mails since 30/05/2024. Has the fact that I received an e-mail message from "Mail@voice" <mboudreaux@firmgroupagency.com> on 31/05/2024, got to do with the problem. I would be grateful could help solve the problem. Thank you. Emyr Davies.

Hello! Since I couldn't find help in the forums, I will create a new question. For about a year now the PC at my work will not open mailto-links correctly. There is no account to select from, the subject has a lock-symbol. The receiver's address is correct though (I replaced it with "address" for the screenshot). This PC is the only one I know with that problem and only with external mailto-links. If I click on an email address inside a mail, it opens it correctly. Thunderbird version 115.11.1 (32-Bit), Win 10

It's pretty impractical, so I am hoping for help. Thank you!
