Thunderbird Support Forum

When I launched Thunderbird this morning the right-hand-side panel is completely blank. The left hand side panel shows my folders and if there are any unread emails in them but the right hand side is just completely blank (as per attached image).

So I've had Thunderbird for a few years. I've always had my (multiple) email accounts set to both check for new messages at startup, and check for new messages every 2 minutes (I keep it open in the background so I can be alerted ASAP). However since the last 2 updates, I can no longer fetch messages either every x minutes, or manually (Get Messages does nothing), and the only way to get new messages is closing and restarting TB completely, defeating the point of having it open in the background.

I've tried: 1) unchecking both 'Check for new messages at startup' and 'Check for new messages every x minutes' = still can't manually pull in mail with Get Messages (the status bar says it's checking, but nothing gets pulled in unless I restart TB)

2) leaving ONLY 'Check for new messages at startup' OR 'Check for new messages every x minutes' selected = nope

3) starting and restarting both TB and my PC = nope

4) checking my antivirus isn't blocking anything = it isn't

5) checking all my email account server settings/passwords are correct = they are

6) testing out Betterbird with the same accounts and seeing if it's still an issue = this also affects Betterbird

7) checking my email accounts are working in other software like Outlook/webmail = they're fine, I can get email there normally

Any ideas as to how to fix this?

Name Thunderbird Version 115.12.1 Build ID 20240618125055

IMAP account on HostGator.

In the last 9 months or so, every once in a while (sometimes several times in a row!) when replying to a message, Thunderbird does not set the \Answered flag on the IMAP server.

I enabled IMAP logging and finally caught this happening. The reply is sent and copied to the Sent folder, as it should, but the original email is never flagged as \Answered.

I can't seem to see a pattern why Thunderbird skips this step, occasionally.

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

Starting 3 days ago: Cannot SEND email - receiving works fine. Error message: An error occurred while sending mail. The mail server responded: Please ensure your email address and authenticating user match when sending messages. Please verify that your email address is correct in your account settings and try again.

The other odd thing is that I get asked for a password before sending which never happened before.

I followed advice given someone in 2022 - I've messed with the account settings (unfortunately) and I've changed the SMTP settings to match what Comcast recommends.

I have 3 comcast accounts; two work fine on my iPad and iPhone - one doesn't

Also I have no problem sending emails using Xfinity/Comcast Mail... but I want to use Thunderbird.

Where do I start looking?

Thanks!!

I'm sure I've made the problem worse by trying to change the setup

Starting a few months ago Tbird suddenly became noticeably slower, and it's only continued/possibly gotten worse, despite several version updates (which I was hoping would fix it). Currently I'm on version is 115.12.1 (64-bit)

I do have several accounts (all pop) and many folders, but nothing different than before the issue began.

I only have 2 add-ons enabled; Remove Duplicate Messages & SmartTemplates. I've of course disabled them and restarted TBird but it didn't help at all.

I've compacted and repaired all folders.

I've created additional folders to reduce the size of larger folders.

The only thing that helped a bit was troubleshoot mode, which definitely made it a bit better going from email to email and folder to folder, and especially with moving emails from one folder to another (which is usually very, very slow and I see it on the bottom saying "moving email 1 of 10 to folder xyz...moving email 2 of 10 to folder xyz...", even if they are simple/small emails). However, sending emails still took over 5 seconds (see screenshot attached), so that might be a separate issue.

In terms of sending emails, whenever I try to send any email it sits on the sending screen for several seconds or more. My internet is fine (2gb fiber, previously 1gb cable), speed tests max out at the 1gb my laptop can handle. Laptop is 2-3 years old high-end Eluktronics, with no other issues.

Given the above, and that troubleshoot mode did seem to help a bit (but straight out turning off add-ons didn't help), what can I try to adjust (while not in troubleshoot mode)?

Thank you very much!

Its driving me crazy. When I select a group of Inbox emails, and delete them, it is taking forever. The window will display a "not responding" message, eventually clear that and then the emails are deleted. But it takes way too long. Windows 11, most recent update. Thunderbird, it just updated. I was on a Win 10 computer, same Thunderbird version and deleting took merely a blink to happen.

Win 10 has both VPN AND AV. Win 11 has neither. Help! Thank you,

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.

when clicking an email link this is shown

"Thunderbird is already running, but is not responding. To use Thunderbird, you must first close the existing Thunderbird process, restart your device, or use a different profile."

How do I make Thunderbird instead open a new email?

This is on Fedora

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!

Have used Thunderbird for 10+ years, as interface to Gmail. Lovely product. 3 days ago I had to reinstall a station but when Thunderbird does its updating after reconnecting to gmail address for the 10GB of emails, it behaves damn irregular: - periodic freezes of mouse and keyboard, for about 0.3 seconds every 3 to 5 seconds. - Thunderbird message says downloading email number out of total number of emails (very slowly advancing) but every 3 seconds it starts downloading email 1 of those emails - station has cumulated some 20 hours working, most of these left to finish syncronizing. Usually in 2 - 3 hours there is time enough.

This happens only when Thunderbird runs, when I close it the station runs fine. Same hardware on the station as before..

Did you encounter this? Thanks.

When attempting to add a second email address to Thunderbird, I get the same error message every time. I have tried updating TB and restarting my computer, here are the steps I follow, please let me know if I should include any diagnostic logs/how to get them as well.

Please note that I already have an account set up that actively works, both sending and receiving gmail. Settings > Account Settings > Account Actions > Add Mail Account Enter my full name, and email address, but leave the password field blank according to other advice on this forum, although I have also tried with entering the address. Press Continue, receive the "Configuration found in Mozilla ISP database." message. Select IMAP > Done. See a google sign in page, with my email already filled in. Select Next. Then I get a Google 400 error page, reading: "400. That’s an error. The server cannot process the request because it is malformed. It should not be retried. That’s all we know." If I close that popup window, there is now a message in Thunderbird saying "Unable to log in at server. Probably wrong configuration, username or password."

Images with more details are attached below, note that this issue persists after both an update and a restart. Please ask any questions that can help you help me. Thanks in advance.

Mam problem z kontem e-mail. Dotyczy on konta obsługi klienta sklepu internetowego. Od kilku dni maile z Amazon, Allegro, Emag itp w ogóle nie dochodzą. Nie wiem co jest tego powodem, nic w ustawieniach nie było zmieniane, stało się to z dnia na dzień. Jak mogę to naprawić?

I had to reinstall the program, I can now receive emails, but I can't send them, my ISP support indicates that I need to have the "requires server authorization" option active, I can't see that option (Google translator)

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.

It has been one year, and you still have not fixed the multiselect functionality that was ruined with your Supernova "update" (which is worse in almost all aspects btw). Can you at least tell us WHEN you plan to release the fix since you locked the comments to block the countless negative ones? Is it so hard for your UX team to understand that removing multiselect functionality is like removing Ctrl+C, and Ctrl+V and set the correct priority???

Hello, I have been using TB for a long time wiht no mayor problem. I recently had a problem with the hosting services of 2-3 of the email addresses I use in TB and when I now open TB I can click once on the pop up (say on cancel), but when the next pop up message appears (with the same message but for another email address) TB freezes.
