Thunderbird Support Forum

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.

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

I tried to update Mozilla Thunderbird to 115.5.0. Now I can not receive emails on my computer. The message I received said, Error: Platform version 115.4.0 is not compatible with version 115.5.0. How do I "return" to 115.4.0 so I can have access to emails on my computer? I can receive emails on my cell phone. Thank you.

I sent a message a while back about slowness with 115, which I had to download because I had a crash.

There were various suggestions, but no solutions to the excessive slowness with 115. This culminated to day in a long 'no reply' mail which suggested the issue might be the virus checker.....

I checked again the various messages about 115 - most were archived, only one month since they were posted!!

Is there an issue with 115?? I saw a thread which asked was I having issues with it, my answer is yes, is there nobody out there with a suggestion??

Open thunderbird up and want to print an email. Most of the time the printer is the default. Once I print and then go to the next email to print, the default printer is gone and the only option is save to PDF. I can close thunderbird and reopen it and seems to alleviate the issue for a few times then back save to PDF only. Strange issue. I have reinstalled thunderbird a few times. All other programs on the pc I print from always use the defaut printer.

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 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?

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

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?

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.

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.

My colleague has updated his thunderbird to version 115.4.1. He As operating system he has windows 11 Home Version 22H2. His "old" thunderbird worked perfectly.

Now he has the following problem: If he writes an e-mail, the "send" button is missing. I've found nothing but a solution in my research. However, he can easily receive e-mails.

Do what?

Just about everything seems slower with 115 from sorting a large column, loading emails at startup, opening an email in a new window, etc. How can I troubleshoot this? thanks, todd

After updating Thunderbird, I can't see my email. There are no emails or even accounts, although there are messages in the program settings and messages are downloaded in the background.

• • So when is the very nice team from Thunderbird gonna solve duplicates issues once and for all? **

Mailer service is gMail. Incoming as normal as POP3. Never see duplicates at my mail account service gMail. Thunderbird version is 115.4.1 (64-bit). Platform is MacBook Pro. OS is Apple macOS Ventura Version 13.6.1 (22G313)

• • Or should I trash Thunderbird for ever? **

Joke, but we all need to have a certain grade of stability. Tired of suffering the nasty issue. Happening as of now since months ago.

Love Thunderbird, guys please commit. Cheers

I have never needed to see every single email in my inbox when I first open Thunderbird but I'd assume it trying to load everything is why it freezes for a few minutes every time I open it.
