Start new Windows session. Start Thunderbird and works OK. Shut Thunderbird down and try to re-start during same Windows session and it will not launch. Reboot Windows and try to start Thunderbird and works OK. Alternatively, going into Task Manager there will be a number of Thunderbird processes running. If I manually end them all (while Thunderbird is NOT active) then I can restart as normal too. This all began with 124.0 Beta 1. Never had the issue prior.

Also, Thunderbird crashes if restarting within the app. By this I mean clicking the X it appears to close (excepting those persistent processes running) but "Restart Thunderbird" such as to launch Troubleshooting mode or from the "Restart to update Thunderbird" config crashes the app with 100% consistency.

I upgraded to Thunderbird 115.10.0 (x64) earlier today and now the program is no longer closing completely (I've tried using the X at the top right of the window, and I've also tried File menu -> Exit). I first discovered this when I was using CCleaner to clean my temporary items and it asked me if I wanted to close Thunderbird after I had already closed it. I then checked my running processes and there are three Thunderbird processes that remain after the program has supposedy closed (Task Manager screenshot attached).

Any help with this seemingly new bug is greatly appreciated!

Much thanks, -Snipe

Thunderbird updated to 115.10.1 (32-bit) and I cannot see any emails now. I use View > Folders > All. If I run a search, TB lists the emails. Have tried opening in Troubleshoot mode but still same, no emails nor inboxes. Windows Security Ransomware turned off for preparing for maintenance prior to TB updating itself. How should I go about fixing issue?

Here in Jan 2024 suddenly TB will no longer connect to any hotmail or outlook..it says I have to enter a new password but I have not changed my password and can get onto them if I go directly to that site. Any suggestions?

I get this message from Thunderbird on my desktop computer on app start up: ]Warning: Potential Security Risk Ahead

Thunderbird detected a potential security threat and did not continue to live.thunderbird.net. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

This started suddenly about a week ago.

I have Thunderbird on laptop that works fine.

How can fix this?

Hyperlinks in Thunderbird (115.9.0 64 bit) running on Ubuntu 22.04.4-LTS have quit working overnight. Too my knowledge nothing changed. I have followed all the steps in the document "Hyperlinks in messages not working" with no luck. 1) My default browser was Chrome. Changed to FireFox. No Luck. Changed back no luck. 2) Check that no application is specified for HTTP content can not be followed No Preferences option exists under the menu in my version of Thunderbird. Checked in settings found nothing matching the description. 3) Checked for incorrect preferences. Used config editor. Their is no Reset option for the settings. Found the referenced setting. Switched from True to False and then back again, hoping the might reset it. No Luck 4) Switched to Safe mode from the Help menu. No luck.

New to Linux, just set this system up 2 months ago. Migrated my Windows Thunderbird database without issue and it was working fine until this morning.

In need of suggestions. If uninstalling is going to be required, I need to be able to do it a way that does not lose my historical email records or my cardbook address book of 1000 names.

Thanks

"Enter Password" box no longer comes up when I start up Thunderbird. One account has password saved but the other doesn't so I cannot access emails on this account now as they won't download without either a saved password or (as I usually do) entering a password. This affects my husband also so not just something on my account. This happened around the 20th December. I've searched through Thunderbird settings but I can't find any way of adding a password directly into Password Manager - only edit or delete. So I can't fix the problem we now both have with accessing new emails. So - any suggestions please or is there a fix coming?, kind regards

Hello,

For a few days I have had the following message for my outlook mailboxes "Login to server imap-mail.outlook.com failed."

I tried to change the password, I tried to remove the address and put it back but nothing to do the message is still there... Do you have a solution?

Of course I use the latest version of thunderbird!

This is probably a mess of my own making, having been lazy about back ups. My laptop threw a critical error at me just before Christmas and I could only fix it by doing a reset and reload of Windows 10. (I think it may have been a partial HDD corruption) I selected the option to retain personal data files etc, but the reload wiped almost all my installed programs, including Thunderbird. Documents, etc folders have all survived. I re-installed the latest Thunderbird and it is working fine. However, I appear to have lost my Local Folders (as well as my address book) Not a life-or-death matter, but I would prefer to recover them, if possible. I have an "..@tiscali.co.uk" (TalkTalk) email account, with IMAP settings on the incoming mail and SMTPS on "sent" items. I can see all incoming emails that are still on the server, but the "sent" items folder is empty. All local folders and contents are gone. I have read up on the Thunderbird Profile and understand that it is separate from the program folder. I have used the "Help>Troubleshooting>..." feature to find that my current profile is "zqx......default-release". Using file search, it also indicates that there is another profile file, "k32....j5.default", in the same area. Both have creation dates corresponding to the reload time. I cannot find anything similar in the "Windows.old" folder that was created at the time of the reload. Is it possible that the folder contents are still in the HDD and it is just the file address that is lost? Thanks. Neil

when clicking an email link this is shown

"Thunderbird is already running, but is not responding. To use Thunderbird, you must first close the existing Thunderbird process, restart your device, or use a different profile."

How do I make Thunderbird instead open a new email?

This is on Fedora

I am getting a non-overridable TLS error when Thunderbird opens or when I attempt to download new emails (the emails will sometimes download later after I force a download. I have tried to change my TLS version without success. Please help me solve this issue.

My email setup is to an IMAP server (POP will not work with Gmail.com accounts). See my attached image files for further information.

I use dark mode (Windows 10 Pro, Thunderbird 115.4.2 (64-bit)). Fresh installation, fresh profile. When I reply to some emails, the reply text is not visible. The examples I saw were with a light (white?) background, but I'm not sure if it also happens with other backgrounds. But it's not all white backgrounds either, some emails with a light background I can reply to just fine.

The reply area can be dark with a dark grey font (slightly different color), or it can be white with a white font. In both cases, obviously the text I type is not readable.

Any idea how to fix this?

All of a sudden all of my Comcast accounts are receiving the message: "Alert from account XXXXXX: Temporarily blacklisted IP Address - Try again later". Contacted Comcast and elevated all the way up to the top technical group and was told it was a Thunderbird issue. Tried resetting passwords, etc to no avail.

Hi All, Greetings!!! For the past two days, I have got the error like "Sending of the message failed. The message could not not be sent because the connection to Outgoing Server (SMTP) timed out". So I have restared our router (Broadband Modem), and then tried to send the mail, but the result is same. Then I have tried using my mobile network (using hotspot method), this time mail was sent sucessfully. Please help me to solve the issues...

Thanks Karthik

Upon initial setup, Thunderbird says the ISP is recognized and auto-populates all the settings. Well of course these settings don't work and I'm unable to log in and receive some sort of message saying it didn't work. If I login using a browser via cellphone, I'm provided with the list of settings to use with email clients which is as follows:

Domain: @hot.rr.com SSL: On for SMTP and IMAP Protocol: IMAP Incoming Server: mail.twc.com Incoming Server Port: 993 Outgoing Server: mail.twc.com Outgoing Server Port: 587 Requires Authentication: Yes, or checked

Using these settings in manual configuration results in receiving the "Thunderbird Failed To Find the Settings For Your Email Account" message. The only difference between the settings that were auto-populated and the settings provided by logging in via web browser on a cellphone are the incoming/outgoing servers. Auto-population had them as mobile.charter.net, and they're listed as mail.twc.com by the email provider to use with email clients.

I'm trying to solve this problem for someone else and they happen to have the same email domain as me so I can fiddle with it without having to be at their computer with their passwords, etc. Presumably if I'm able to find the solution it will work for both of us. I don't normally use Thunderbird or any other email client, I just use web based email but they prefer to use a client. However, I'm doubtful that it will work considering the fact that settings provided by the email provider don't work.

Any input is appreciated.

Hi. I have used Thunderbird for a long time. I have never had a problem accessing my hotmail account for emails. Overnight Thunderbird now posts error message boxes when trying to login to the hotmail server. It reports incorrect username or password. Neither has been changed by me and comparison with Eset Password Manager shows them to be correct. I can login to Outlook online using the same login credentials an get my emails that way. I have also changed my Outlook hotmail password while logged in in my browser and updated everything on the PC to match of course.

I have massaged the server Settings for hotmail and have had the system working again, for a while. Twice I have reset the settings to a different server and back again and that seems to clear the problem for a while. Then the error messages switch on again consistently. At this moment using "File" -> "Get New Messages For:" -> "Hotmail" works without any problem and the automatic scheduled checking reports "No messages to download" so it appears to be working. But that is after just coming back to my PC to find a string of failed attempts, each with its own error box, which have appeared since I last "fixed" the problem and assumed it was now fine.

My server settings are Type: POP; Name: pop-mail.outlook.com; Port: 995; Username: same as for browser access (which works); Password: As in Thunderbird's stored passwords matching Password Manager and working browser access.

In my paranoia I have even wondered if I am being locked out by Microsoft somehow. Can anyone suggest what is going on here?

I have used Thunderbird for many years without a issue. But as of a couple days ago I have been getting errors when I open Thunderbird. 1) It always ask me to login even after I save the password to always login. 2) I get this message: "Login to server imap.comcast.net with username caulkerguy@comcast.net failed." 3) Then I get this error message "Alert from account caulkerguy@comcast.net 1014." I have checked all my Server settings and all are correct as per your online settings. I have searched the web and have not found any fixes. Are there any fixes or work arounds? I would hate to stop using Thunderbird as I really like it! I have included 2 screenshots.Thanks for any and all help! Mike: caulkerguy@comcast.net or caulkerguy@gmail.com
