In Android Thunderbird version 18.0, embedded photos from my webcam are no longer immediately visible within the HTML email view and integrated into the message. Instead, they are now displayed as attachments. In all other clients, as well as in Thunderbird for Desktop, everything still works as expected. It also worked correctly in previous versions. With version 18.0, without any changes to the settings, this behavior has changed.

This is incredibly annoying and makes it practically unusable. Is there a solution, and is this recognized as a bug or intended as a security feature? If it is the latter, I kindly request that it be made configurable in the settings.

I used to get REMINDERS for all events/tasks until about some months ago. But now I don't get the reminders for most events/tasks. rearly I do get reminders randomly and ocasionally. I have been using TB (Thunderbird) for many years without any problems. I update TB religeously as updates become available. Please advise the fix. Thanks in advance! Anil Deshpande

I have Thunderbird on Windows 11. I have been using Local folders for a long time without any problems. I now find that if I try to delete subfolders in Local folders, they reappear as if they had not been deleted. This applies to any mails I have received since 28th January 2026. Could this be associated with a windows update?

After tried many suggested steps to trouble shooting the problems, it still can't download Comcast emails. It keeps pop up "enter password" or "password failed" again and again. But I can send emails. I can't upload the trouble shooting information file to send. Thanks

I have all my emails filed in 50 +/- folders in New Outlook. I would like to transfer/copy them to Thunderbird on a new computer (Windows 11). I have both new outlook and thunderbird set up on old computer (Windows 10).

I am using Thunderbird on Linux, there is an option to delete mail on trash on exit, and that worked. I don't see such option on the Android version, and the notification did not clear even I deleted all the mail.

Hello!

I am using Thunderbird 140.9.1esr (64-bit) on a Ubuntu 24.04 system. Every time I restart Thunderbird, it reverts to a little used Gmail account as the default account. I have several accounts, but my main email account is a MS365 account. I reset the setting, but every time it is restarted, the default goes back to Gmail. I have tried everything that I've found online, but cannot correct this behaviour.

Do you have any suggestions or assistance?

Many thanks!

I can't access to my personal Google account from Thunderbird.

Thunderbird configuration is OK. Cookies authorised.

e-mail account connection process goes this way: - I enter name and e-mail address - I confirm standard configuration found in Thunderbird's FAI database. - Google asks me to confirm that I authorise Thunderbird to share mail, contacts and agenda informations (I was asked my Google pwd only the first time I tried the process). - I confirm my consent - Back to Thunderbirds account configuration window, with "authentication error".

Similar failure when I try to only connect to the contact list or to my calendars (which is my initial will), also from a scholar Google account.

No change after update from 149 .0.2 to 150.0

I have been using TB to access my Office365 account using the TB Oauth protocol, however, it got to be painfully slow when trying to download messages. I had set up rules and folders that worked, albeit slow.

To try to alleviate the slowness I started a new profile to my Office365 account again using Thunderbird's OAuth protocol. It's lightning fast! But it didn't bring down any of my Office365 folders that exist up on the Office365 servers. (see 2nd TB Install screen print below) It had brought down all the folders and previous e-mails in the 1st installation. (see 1st TB Install Redacted. Screenprint below)

I don't know why this might happen, does anyone have any ideas? Is there a workaround or could I be doing something wrong?

Thanks

Good afternoon! I have always had a specific folder order in my email, with the inbox folder being the first, followed by the sent folder, and so on. However, today I discovered that the inbox folder was at the bottom of the list, while the sent, spam, deleted, and other folders were above it. I was unable to change the folder order back to its original state, and I have been unable to drag and drop or swap the folders. Can you please advise me on how I can restore the folder order to its original state, with the inbox folder at the top and the other folders below it?

When I try to create a calendar event.. Error Message: Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtp-mail.outlook.com timed out. Try again.

Hello dear support team Some e-mails in the Inbox are of a huge size, like 32 MB and more, even without attachment. I already used repair function, but it stays the same. In Outlook, the same email is of normal size (80 kb). So, it is not the e-mail provider or the database at the provider. I have had this situation throughout several updates, so it is not specific to a certain update. The ones that have an attachment and the same problem (attachments of less than 1GB but show 42 GB) cannot be moved. The error dialog says: to big to move. Also, the attachments cannot be removed as they show 0 kb and the attachments name is crossed out. This is not true for all mails, but some have this problem. What do you recommend?

Active Sync 16+ is now in force and Thunderbird has lost the sync via TBsync, so contacts and calendar syncing is now dead, unless TBsync is updated quickly, seems unlikely from reading their website. TB has advised that contacts and calendar are still on a dream list and no date for implementation is known. So TB is no longer a substitute for users wanting to escape Outlook. I am a long time user of TB and a donator, so why have you not pre-planned the inclusion of contacts and calendar sooner or even included TBsync into the code and kept its syncing ability uptodate.

TB with just email sync is no different to many email apps that come with laptop and tablets, so I may as well revert to using in my case Apple Mail.

I used to be able to drag and drop emails from my inbox into an archive folder. That no longer works. I now have to right click the email, select "move to", then select the account containing the archives, then select "archives", then select the destination archive I need to send it to. On the right click drop-down there's an option to "move to *** again" but if you're moving emails to different archive destinations, that's not very helpful. Is there a setting to reinstate drag and drop?

I receive emails from one source that's supposed to have a banner image at the top. In Thunderbird it shows the broken image icon and the image as an attachment. But in RoundCube it shows as expected.

The html shows:

The image part of the email shows: content-id: <piXdKIOofB>

I'm guessing that those angle brackets around `content-id` are breaking the display, such that it's calling that a mis-match.

Hello! No real issues or bugs to report, but I had some curiosities about independent audit documents. I appreciate the dedication to privacy and transparency, as I am sure many do; I've noticed that there are readily available audit documents for the Thunderbird Send and K-9 which is cool - are there any such audit documents for Thunderbird Desktop for Linux, or do the aforementioned documents sort of cover the same thing? If you could help me understand this (or perhaps point me to information or docs I missed), that would be appreciated!

Thanks for your time, --Mark

On both my accounts "Sent" has popped up twice and on bjornla1bn@gmail.com I have been blessed with two "Spam" files. This is most annoying causing trouble. How can I correct this without loosing data?
