Hi, I have a python script that send notification email from my server using an outlook account. Microsoft recently changed their security requirement in June 2024. So, I cannot just use SMTP with password anymore, but I can send an email using Thunderbird.

My question: Is there an API for Thunderbird that I can use to send my notification emails ?

regards, DG.

As of yesterday there is a issue on both my computers. Email does not get send. If you create a email and then press send the window somewhat dimes and nothing happens. It is possible to save the email in the concepts folder after the message window is closed. Secondly Cardbook behaves funny. If you select a group no contacts are shown at all. Only if you select the address book contacts are shown. I retrieve my 300 contacts from a NextCloud server. I depend havily on as being active in two different bridge clubs. When I watched the Cardbook screen I saw that the contact were not updated. It happened when I manually started the process. I hope for a solution because I use mass mailing with Thunderbird.

I set up multiple Gmail accounts on TB, and all work as expected. I have turned off Win 11 telemetry and I use an always-on, kill-switch VPN. On TB, each of the outgoing SMPT servers is set to a different Gmail account.

Keeping in mind the settings, above: can Google determine somehow, through TB keys/OAUTH/data/settings etc., that the user of one Gmail account is the same user of another Gmail account?

Also, I can post this question to the separate Android blog, but if anyone here knows the answer to the same question with K-9 (F-droid version), I'd appreciate it.

This is an odd one, and an hour of googling now has turned up nothing except one person on Reddit from 6 months ago with the same issue.

When I open a messasge with an attachment, either in a new window or tab, and at the bottom of the window I click the arrow to expand the list of attachments included with the email message, if I click to select one of those attachments, I would expect that pressing the spacebar would launch a Quick Look to preview the file.

I am moving over to Thunderbird from Postbox (which I should have done long ago, frankly). Postbox is Thunderbird based, and I had no problem with the quick view of attachments in Postbox. I assume there's a configuration setting or something I'm missing that's not allowing me to use quick look to preview attachments. Or, is this by design (or rather, lack thereof)?

Running Thunderbird 128.3.3esr (64-bit) on MacOS Monterey.

Thanks for any input you may have.

I am not very tech savvy, so I apologise if I have asked this question before.

Having just downloaded Thunderbird and trying to add email addresses I keep getting a pop-up asking for passsword. I have tried every password I have with no success.

The pop-up says: Password Required - Mozilla Thunderbird.

Having never, to my knowledge, created a password for Thunderbird, I am stumped.

Any suggestions much appreciated.

Hi,

I have an issue: How to change the location of the Thunderbird's profile folder to another partition (non system)?

When I do so by: 1. Changing in setting destinanion folder to the new one; 2. Closing the program (Thunderbird); 3. moving the directory folder with my profile to the new destinanion according to procedure below: https://support.mozilla.org/pl/kb/profile-thunderbirda#w_przenoszenie-profilu 4. Starting the program it end with error of missing profile.

Hello, I've been using thunderbird since 2013, and have never had as many issues as I have this year. I reinstalled Thunderbird (uninstalled with revo uninstaller so nothing stayed), and then installed the latest version fresh. This seemed to smooth out most of my issues, but I haven't been able to solve this one..

I use Thunderbird because I have multiple email accounts to monitor and like them all in one place. The latest problem that I am having is that my "sent" email is showing up as giberish (sometimes.. Not every email, and not always on the same account).

My system is Windows 11 Home 64-bit

I will attach a screen shot of: 1. My current version of Tbird 2. The email that displays in Tbird 3. The email that displays in Gmail

Thank you in advance! -Eric

When opening an "ics" attachment I was given a popup modal, where I could change the default behaviour when clicking an "ics" attachment. I opted for open with thunderbird as a default, however I want to change this. When looking under "Settings" -> "Files & Attachments" only PDF and Text File are listed as content types with an according action. I also tried right clicking the attachment to see what options I would get but there are only the options "Open", "Save as...", "Detach..." and "Delete".

So there is no way for me to change the default behaviour of "ics" files that I could find.

Does anyone know how to change this?

I am using MacOS 15.0.1 & Thunderbird 128.3.3esr

Before the Thunderbird update to Version 128.3.1esr it was possible to click on an Event in the Lightning Calendar and drag it to a different day. You can still do this when the Calendar is displayed in 'Week' mode, but now you cannot drag an event to a different day when the Calendar is displayed in 'Multi-Week' or 'Month' mode.

Hi.

I have af mail account at One.Com - for years no problem with using Thuinderbird. This morning I am not able to send mails from Thuinderbird. They stays in draft. I have done every thing surgestet at thunderbird support. I have been dialog with One.Com.

I can create a MS outlook IMAP mail and send with no problems.

Hi, after an update to the functions 'send' and 'send later' do not work anymore with no error message. Just doing nothing. When I send the email via Mail Merge, it works. What is wrong, what can I do? /Hans

Problem: newly added account disappears when TB is closed. Thunderbird on this PC (Dell Latitude 6540) has held a Verizon account for years. The "new" account is a different, equally old Verizon account kept on TB in an identical PC I no longer use. When added to TB on the present PC it tests and works fine until TB is closed. Repeated numerous times. Having read thread # 1286437 I did what follows , to no avail: 1. tried TB in troubleshoot mode; 2. tried in Windows safe mode; 3. cleared startup cache; 4. drastically pruned old emails; 5. looked up profile folder under troubleshooting info. Folder qxxxxxxd ( size 1.18 GB before adding new account) holds one folder tree, one directory tree, but NO prefs.js file. Instead, twenty-two prefs-xx.js files from 1 to 22; removed all to a thumb drive except prefs-1.js which I dared not rename as prefs.js; 6. found two profile folders, both labeled default. One is the above holding 1.18 GB, the other holds 685 MB (probably harmless and related to an old university account no longer extant). I copied both profile folders to a thumb drive. Note: profile folder qxxxxxxd is clearly engaged in what I am attempting. When TB is open with the added new account working -- which is the case as I am writing --, profile folder size increases from 1.18 to 1.20 GB and the number of folders increases by one (under "Mail" the list of pop.verizon-xx.net sub-folders increases from 17 to 18). Please advise on what to do next; I am 86 and no software geek, but can follow instructions... Thanks --Paul

When I first open Thunderbird 128.3.3esr, the Status Bar shows the progress of querying email servers and of downloading messages. After a while, however, the progress messages stop appearing in the Status Bar. Messages download properly; there's just no message in Status Bar showing progress. When this happens, the Online/Offline button also appears grayed out.

I am using Thunderbird 128.3.1esr on Linux, using the KDE's Plasma 6 desktop environment with KWin using the Wayland protocol.

I have installed two add-ons whose interface is blank: Tag Toolbar/Tag Popup and Tagger. Their interface opened when clicking on the button placed in the toolbar is blank. Namely, there is nothing to see but white space in the box that opened. For Tagger, it is possible to actually interact with the non-visible interface, but for Tag Toolbar this does not seem to be the case. I've attached a screenshot of Tagger's blank interface.

• What could be the reason for this visual glitch?
• Has anyone else encountered something similar before?
• Is there more information I can gather to help resolve the issue?

After rebooting my Mac (MacOS 10.15.7) and opening Thunderbird (128.3.3esr), the inbox display looks messed up. The columns are in different places, and the headings don't match.

See the enclosed screenshot: The subject of the mail is listed under "Correspondents", the sender is listed below "Size", the column for the "favorite" icon (big star) is ridiculously wide and can't be made smaller, the column containing the "spam" symbol has the heading "Date". The column holding the date column is only showing about 3 characters of the date and can't be made wider.

When I worked yesterday, everything looked normal.

How can I fix this? What could possibly be have messed up the settings?
