Thunderbird Support Forum

I previously posted here about an issue where Thunderbird would display document icons instead of folders in the Favorite Folders view, and also put these icons at the top of the list, out of alphanumeric order. In the previous thread a fix was suggested...

...but that fix no longer works, and new folders on a brand-new installation of Thunderbird (with no previous profiles on this system) now exhibit the same behavior.

The Favorite Folders view should display folders using folder icons and in alphanumeric order. What steps can I take to ensure Thunderbird does so?

This is on 115.7.0 running on MacOS 14.3.1. Thanks.

I'm using Thunderbird for email and it's worked without flaw for maybe a decade. As of a few days ago it's not connecting to the Hotmail server to retrieve emails. Initially it had forgotten and asked for the password and when that was entered, and checked remember password, it connected and downloaded emails. Now it's not even doing that. Could someone please let me know what my Connection security and Authentication method should be set to? Currently it's SSL/TLS and OAuth2. I've tried every possible combination with no success. The sever is pop3.live.com and the port is 995. Thanks for any help.

Suddenly all of the hundreds of messages in my inbox have disappeared. Even newer messages appear briefly and then disappear. They are not in my Trash file or archived. They are just gone. This is a disaster, as several of the messages were needing to be responded to.

My Thunderbird just did an auto update and now the new update screen does not show Thunderbird at the top of the page or the usual About options or reinstall a previous version. I lost all of my important folders and my 3 email accounts with their folders. What happened? And, how do I get them back. I cannot even tell what version of this Thunderbird I have now !!!!! The image below is what my new Thunderbird page looks like. :(

After entering Safe Mode to troubleshoot the hyperlink issue, 2 of 3 email accounts were deleted. After reinstalling them there are so many issues to report.

The most annoying is when replying to a message in a Folder under Local Folders no From account is selected, and no Subject until I remove the "re:" and it won't send until I save it as a draft, then edit and then it will send.

Emails work normally when replying if they are not in a Local Folder.

Several other issues but I'll start there. I've been using Thunderbird for many decades and have not had these issues before.

Thanks,

My account is not sending or receiving emails. I have always had to enter a password to access my account and now it is open without a password. I am trying to access some important emails! I tried logging in through Yahoo and cannot access there either. It tells me it has sent me a code to my email! If I click on try a different method it tells me to try again later. Love that your site asks me to tick 'email me when someone answers'

Hi guys,

I have a weird problem with my thunderbird on my PC.

I really want the icon pinned on my taskbar but no matter what I do it keeps removing itself once I open thunderbird.

I tried all kind of things, creating a shorcut and pinning it instead of doing that from the start menu, pinning it from the start menu, from desktop, from the app .exe itself. Nothing, it keeps removing itself!

I don't have this problem on my other windows machine so I really don't know what to look at.

Thanks in advance,

Mauro.

Hi everyone!

I'm trying to authenticate to my corporate email, which uses Google Mail, but I'm having some issues due to the security requirements. To authenticate to the email, I need to confirm the authentication with a Passkey, which I use the Bitwarden password manager. When I try to authenticate the email in Thunderbird, it opens a "browser" window where I should provide my email, password, and confirmation through Passkey. As this "browser" doesn't have the Bitwarden extension installed and is impossible to install, I cannot confirm the login.

Is there a way to change a configuration on Thunderbird instead of opening its browser, opening the browser installed in my OS where I have the Bitwarden extension installed, and logging in to confirm the login through Passkey? This behavior is the one used by Mailspring to authenticate an email account.

Since (I think) installing the latest version of TB SuperNova 115.7.0 (64-bit) emails are not stored on my MacBook. They load, I can send emails but they disappear and all my various folders over the years are empty. From Synchronization & Storage I have "Keep messages in all folders for this account on this computer" checked. When I log into my "Google Mail" account I see all some of my previous mail. Very confusing. Obviously a setting someplace but where else to look Thanks for any advice.

Hello :) I am using Thunderbird on Fedora 39. I am also using the OWL add-on which I guess is on a trial for the next 30 days.

Anyway; my one and only email account is hosted Exchange (office365) through Rackspace. When I set up Thunderbird to use my email, everything seems to work and work flawlessly with the exception of Contacts.

All of my contacts are listed, but they are all mostly missing their phone numbers and addresses. I have not LOST any data to my knowledge (My mobile devices and three other computers running either Windows 11 or macOS Sonoma still show all of the missing information). My concern is that if this info is missing and I go to put in a new address or phone number in Thunderbird, that I might mistakenly delete information when updating a record when it goes to sync.

Anyone know what is going on?

Thunderbird, with the latest update, will decide on its own who moves some inbox item or two to the archive file without me doing anything. When I discovered the emails in the archive file I can move them back to the inbox without any problem but I would like to stop Thunderbird from sending anything to the archive unless I tell it to do so.

I would appreciate any insight I could get from anyone on what may be going on and how can I resolve the problem.

Hello, Recently, some attachments, such as photos, are no longer displayed as attachments in Thunderbird. This is not a problem in the mail program on the smartphone. Do you have any idea what setting I need to change to get the attachments displayed again? When I forward the mail, the attachment is displayed in the mail to be sent. I hope you can help me. Thank you very much.

Best wishes Stephan

Why does Thunderbird INSIST on directing web links to Bing?

I have changed the Windows Default browser to FireFox.  I have restarted my machine and restarted Thunderbird multiple times.  When I go to Windowz settings it tells me that FireFox is my default browser.  Yet Thunderbird continues to direct links from an email to that CLINKING CLATTERING CONGLOMERATION OF COLLIGINOUS JUNK that is Bing.

Any help would be appreciated.

Hi,

My wife and I both have our comcast email accounts on the same Thunderbird. Every so often my email{incoming} fails, asking for my password{error 1014}, which doesn't work. S, within TB I some how reset it and we are back in business. This time, I cannot remember how to do it!!!!!!! Can you help? I cannot get my emails or send. My wife's account is somehow fine. This all happened after I replaced my comcast router with a new Comcast router today.

Thank you, WILLIAM

When I double-click on an event in my TB Lightning calendar, the event details window/popup/whatever-you-call-it opens up at a fixed size which 90% of the time is too short vertically to see the Edit button. This forces me to have to resize it manually just to be able to click on Edit. This is making the calendar very annoying to do. Any of the following might help:

1. How can I change the default popup window size?
2. How can I make the manually selected size sticky?
3. Can you change the default size to automatically be tall enough for the Edit button to be visible?

Thanks for your help

Fresh Thunderbird (115.7.0 (64-bit)) install on windows 11. Set up my POP3 (x4)accounts okay, but missing any form of the address book. When I click on "Tools" > "Address Book" , or hit CTRL+Shift+B nothing happens. The program is grabbing email addresses as when sending new messages I get the contacts button with previously used addresses, but no actual address book that I can add/edit addresses. I did try un-install and re-installing thinking i just had a bad install.

The second issue is that Thunderbird is no longer automatically retrieving emails on startup, even though I have the option checked for each email account. It is retrieving on the 10 minute intervals that I've set it too, but not on startup.

I'm a long, long time Thunderbird user, this is the first time I have ever had any issues. Any help would be much appreciated. Cheers

For no particualr reason that I can see, all my email subfolders have disappeared today (15 Feb). they were OK yesterday. Very worrying as the filing systems separates and keeps all things I want to keep. Can you help please ? What have I done and can I restore them somehow ? Adrian Simmerson

I have a new (one month old) Lenovo Yoga Book 9i with Win 11 and Thunderbird 115.7.0 (64-bit) installed, using Maildir folders. When opening another tab or window to view another folder (Right click, "Open in New Tab" or "Open in New Window"), the new tab or window opens in the new folder as it should. But so does the original tab/window! Opening further tabs and windows and switching between tabs/ windows and clicking on a new folder in any of the open tabs or windows results in all tabs and windows always being synchronized.  In other words, I cannot view two or more separate e-mail folders. They always all synchronize back to one folder. I can never have two different Thunderbird e-mail folders open at the same time!

Never had an issue like this before on other computers or earlier versions of Win/TB, including the same version of TB set up exactly the same way in Win 10 on another computer. As this is my only Win 11 machine, I cannot test it elsewhere. Has anyone else experienced this? Is it a problem with Win 11? Is there a solution, TB config setting perhaps?
