Hi All,

I am on the latest release 156.0 on Windows 10. I have 3 email accounts, 2 gmail and 1 yahoo. The Yahoo account has been giving me problems since the last 2 weeks. Mind that yesterday I have a completely new Windows 10 installation so also TB installation is new.

I have renewed the Oath login, all messages were downloaded without a problem, but once in a while I get different notifications about server errors such as the ones below. There's also a third type of message error but haven't been able to get a screenshot of it.

Could someone please help me to solve this issue? I really don't understand why the problem is intermittent. Thanks in advance!

My Thunderbird (windows) is really not working, so I want to reinstall the whole thing. I have 4 accounts and a local folder. I don't want to backup all the profiles before reinstalling, as I am having an annoying issue with g-mail (I don't HAVE a gmail any more, but Thunderbird wants to login to gmail every time I open it). I only want to backup the "local" folder, as, so I want to reinstall the accounts one by one from scratch. In that way I hope, I can purge Thunderbird of the gmail. Now the question: How do I backup the local folder in a way that makes it easy to import it back after all the reinstallment?

I run Thunderbird on MacOS for some years without a problem. Now, after a hard reboot, Thunderbird won't launch anymore. I tried reinstalling to no avail. Is there anything I could do here? Or do you need any more info? The crash report is as follows:

Mozilla Thunderbird installed on new WINDOWS 11 laptop in May 2026 as an email client for BT MAIL. It has continued to function without issue until early September. At which point it became an issue with sending emails difficult and mostly impossible. When sending I have been prompted to enter my account password, sometimes this would be accepted, but often not as the outgoing email would fail to be sent. The reason given that Thunderbird could not connect to the outgoing BT MAIL SMTP server, even though none of these settings had been changed since installation using IMAP. However a connection test is always a positive result and a certificate is provided. As I write today i have been able to send and/or FWD a few emails, but have no confidence that this will be the case going forward. Last week I made a one off donation to Thunderbird and after rebooting the laptop, I was able to send messages, but only for that day ! The sending issue reappeared the next day.

On 28 August I received a blank email with just the sender and subject showing. Since then I have sporadically received completely blank emails, with no sender or subject, while others are arriving as normal. The same is happening when I open Thunderbird on my mobile, but not on my laptop which has an older version installed. It would seem that the issue is caused by update 153.1.1esr, as that was released on 28 Aug.

Can I revert to a previous version of Thunderbird or is there another way to fix this, thanks.

Installed Thunderbird in August 26. Successfully added Outlook and Gmail accounts (send and receive)

On a roll I then tried to migrate from Plusnet to Greenby. Can successfully receive emails via IMAP.plus.net server. But could not send mails from Greenby (other accounts still OK)

Traced problem via forum query 31???? to inability to create a new SMTP server for outbound mail. After entering all data in the outbound server there is no response whatsoever to clicking add button (ie no error messages or servers added to SMTP list)

Then tried to delete the partially active Greenby account via clicking delete button in account setting window. No response. Account still present.

Does anyone have any suggestions to solve this before I try the doomsday action of deleting and reinstalling Thunderbird.

TIA Phil

I have copied Thunderbird folder from C:users\maris\AppData\roaming on old PC. Had it working on the new PC, but it suffered an unrecoverable error during a windows update after only five days. Other reinstalled apps now running OK, but have been unable to replicate the successful installation from a few days ago. Found additional profiles in profiles.ini and deleted them. Made no difference!

I updated to 155.0.1 via the update modal yesterday, on MacOS Tahoe, and it didn't restart as normal. The main message pane was blank with "No Message Found" (screenshot attached).

I tried installing a fresh 155.0 over, that did not work; but, a restore of the prior app from my Time Machine did work -- that is, the application not the user profile data.

I just thought this was strange; never ran into it.

If there is an issue and I can help test it usefully, I happy to do so (I have backups! LOL).

I’m trying to understand how Thunderbird handles links to online media when an email contains a link to a photo or video rather than a normal attachment.

For example, if an email contains a link to public Instagram media, I may open it in the browser and use a browser-based option such as Indown.mobi to work with the media. Is there any Thunderbird setting that affects how these external media links are opened or handled?

I’m mainly interested in understanding whether Thunderbird treats these differently from normal attachments and whether there is a recommended workflow for managing them.
