After updating to Thunderbird version 140.0esr, I am unable to create a new email. Clicking “Write” or “New Mail” does nothing – no compose window opens. However: • Receiving and replying to emails works normally • Safe Mode does not resolve the issue • Disabling all add-ons has no effect • Reinstalling Thunderbird did not help • I confirmed I am using version 140.0esr

What can I do if I cannot receive an incoming messages but can send? I am using a POP3 mail, I notice that it started on July 7, same date of launching of upgrade to 140.0esr version.

For the last several days, if I get an email with a link to open in a browser (e.g. a tracking number, and Amazon order, Ticketmaster order), clicking on it doesn't bring it up in my browser (Firefox). It shows a blank window.

I have the latest versions of Thunderbird and Firefox, with the current Windows 11.

How can I fix this problem?

When I try to forward an article (to myself or others), I get a message: "Do you want to allow this app to make changes to your devices?" Whatever button I click on, it goes into Set-up mode, though it's already set up on my PC, and getting out of the sequence is difficult, like navigating blind alleys to nowhere.

I get the following error when trying to delete emails:

Messages cannot be moved or copied because writing to the folder failed; to gain disk space, go to file, empty trash, then compact folders.

I have tried this and all trash folders are empty, yet the message remains, I cannot delete, move or receive emails. There are 970 emails in my inbox... I even rebooted several times after doing the above and it still does not work.

What ever instructional help is provided, please include how I can save some of those emails if possible as I don't want to loose them... Right now I have had to go to spectrum to be able to read any incoming emails. Thunderbird is bricked....

Please help...

Thank you

When I select a folder with the columns and column widths set the way I want, then do "Apply current view to > Folder and its children > Local > Local" Thunderbird applies the view to some, but not all, folders. Even if I target a problem folder and explicitly attempt to apply the desired current view to it, it doesn't work. If I create a new blank folder as a sub-folder of a folder that *does* accept current views, I can't apply the current view to the sub-folder. It retains what appears to be a default view.

I can't see any difference between folders that accept "current view" and those that do not. Any suggestions? Or is there a way to set the default view (i.e., columns and column widths, not just sort order) for new folders?

Não consigo abrir ou visualizar as mensagens em nenhum das pastas após atualização da versão 128.0 pois as mensagens (repositório/armazenamento) estão em um servidor na rede, apenas quando as mensagens estão na máquina local as mensagens são todas visualizadas. Instalei a versão 115.9.0 e apenas nessa versão para trás que é possível visualizar as mensagens com seu repositório no servidor de rede.

I received a request for donations for the 100th time. I have donated to the group more than once, and coincidentally, my system crashed and prompted me to make another donation. We need a permanent fix to stop the donation requests and get Thunderbird functioning properly.

I've been using Thunderbird for decades. I have Thunderbird set to automatically download messages every 5 minutes. Platform: Computer Win11 Home, Thunderbird 128.10.0esr (64-bit), POP3 connection (also with IMAP connection on a MacOS computer.

But a new issue is now occurring. Every so often now, I realize I haven't received any new email downloads in some time. I click on the Get Messages button (or right-click and select items individually), but nothing happens - no "Host Contacted..." message in the Status Bar. It's like the Get Messages function is completely disabled. It is only when I quit then restart Thunderbird does it successfully establish a connection and download the many queued emails.

Please let me know if this is a known bug, or if there is a way to submit this as a bug. Also let me know of any other information you would need in order to help debug this issue. Thanks!

I had to reinstall Thunderbird after getting an update/error message. After reinstalling it, my ScanSnap scanner won't send to my email anymore. I have reset all my settings to what they should be but it still won't scan to my email. The error message I get is "Either there is no default mail client or the current mail client cannot fulfill the messaging request. Please run Microsoft Outlook and set it as the default mail client." I have Thunderbird set as my mail client right now.

When I tried to log in to my Google Email account, the authorization pop-up window that appeared was completely blank. I have tried operations such as re-logging in, but it still didn't work.

I am using my University of Florida email (https://www.mail.ufl.edu/), IMAP. When I turn on Thunderbird and I send messages, everything is good for a few hours. After that, when I send an email I get this error every time:

Your message was sent but a copy was not placed in your sent folder (Sent) due to network or file access errors. You can retry or save the message locally to Local Folders/Sent-XXXX@XXX.

How can this be solved? Only way to fix is closing Thunderbird or rebooting, then problem represents itself. But then I lose the sent emails.

Note: could the problem be that by Default Thunderbird saves emails in a different sent folder? Which is not ideal, because when I send from my phone or from the web things go in a different folder than when i send from Thunderbird. Should I tick off "others"? in the attached pic? How should I consolidate the 2 "sent" folder into one? Should I manually copy them? Or after I select "others", they consolidate themself. I dont wanna do a mess, can you please provide step by step instructions.

I have an e-mail in my TB in-box. The mail contains a hyperlink to Facebook. When I click on the hyperlink, I get the message copied above in the Subject of this problem. In almost all cases, if I re-click on the icon in the e-mail, the re-click takes me to the desired URL in Firefox. My Thunderbird is 128.11.1esr (64-bit). Why is the first click producing the error message? Would there be anything in the TB Error Console?

I've been a long-time Thunderbird user with a POP3 account (Google Workspace), and I’m currently dealing with two critical issues. I have over 50 GB of email data accumulated over the years, and recently Thunderbird has started behaving erratically.

1. Thunderbird consuming unexplained disk space Thunderbird is using a significantly larger amount of disk space than my actual email data. For example:

- Windows reports that the disk is using 65 GB, but when I check the contents of the Thunderbird folders, they only add up to 55 GB.

- There are no hidden or temporary files accounting for the difference. - The problem worsens when I compact or repair folders. Initially, the unaccounted disk space was about 5 GB, but after compacting, it jumped to 10 GB, then 15 GB, and eventually over 50 GB.

At that point, I backed up all Thunderbird data to an external drive and formatted the original drive. This restored full disk space (195 GB free). After copying the Thunderbird data back, everything seemed fine—until I launched Thunderbird again. Immediately, disk space began depleting rapidly with no visible cause.

I’m at a loss as to where Thunderbird is storing this data or why it's behaving this way.

2. Emails missing randomly Some emails are intermittently disappearing from folders. I have to frequently "repair" folders to make them reappear. This is happening every few hours now. Additionally, repairing or compacting these folders seems to correlate with the unexplained disk usage problem mentioned above.

Attached: Screenshot 1: Showing 124 GB free of 195 GB (i.e., ~71 GB used) Screenshot 2: Showing only 65 GB of disk space used based on folder contents (no hidden/temp files)

Any help or insight would be greatly appreciated. Thank you in advance!

Good day, I've had a problem for some time now and I can't figure it out. I get messages that the POP certificate is invalid. I use Cyber-Folks hosting and everything worked until now. I have a pop.etertech.pl domain and it works on that. But Kaspersky antivirus sends messages that the certificate is invalid. What should I do? Where should I look?
