Thunderbird Support Forum

I've been using Thunderbird for years and have never had this problem. Since the upgrade today, after I run Thunderbird once and close it I can no longer start it up again. I have to reboot or use Task Manager to kill it in order to run it. This is on Windows 11. Please help - not an acceptable workaround for long. Optionally, how do I downgrade to previous version? I should know better than allow automatic upgrades.

Adding a couple images below, when it has started successfully it shows as one of the Apps in Task Manager. When I close it, Thunderbird drops into the Background Processes but doesn't end. I have to kill it here in order to start it again.

We have been using Thunderbird with a Cox email account. Cox has just transferred all its customers to Yahoo. I want to use Thunderbird with Yahoo. How do I set that up?

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.

Windows 10 22H2, Thunderbird 115.5

Thunderbird periodically loses my saved passwords (11 accounts) necessitating the re-entry of said passwords. This has been happening for about six to eight months.

I have searched for solutions and have tried deleting the pkcs11.txt and secmod.db files but the problem reoccurs. There is no rhyme or reason as to how often this happens. If I new where the passwords were stored, I could copy the good password file back into the thunderbird directory.

Any suggestions would be greatly appreciated.

Thanks.

Running 115.5.0 and want to export my contact list to be able to use it in a spreadsheet. The export function in the Tools dropdown only allows for export of "accounts, messages, address books and settings to a ZIP file." What happened to the ability to export just the address book separately to a csv file? Please help. Thank you.

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 just got the new "supernova" update and now I can't find the stettings to place my tabs bar at the top of the screen. The old version had the tabs right at the top, just as a browser would typically have it as well (see new and old schreenshot for comparison). But I'm just unable to configure it that way.

Can anybody please tell me how to configure thunderbird to use all that wasted space at the top sensibly?

There is an email account profile on my Thunderbird email program and I simply cannot get rid of it. I have tried everything including running the program as an administrator and nothing works. None of the instructions to remove an email account anywhere on this forum works. When I go into the account settings, there absolutely no selection for me to remove a particular email account/profile from Thunderbird. I have removed Thunderbird, wiped out all traces and profiles for Thunderbird, reinstalled Thunderbird and this particular account keeps coming back. I bought a new computer, installed Thunderbird on that, and this particular email account suddenly appears on the new installation on a new computer. I can't get rid of it. I brought both computers to a technician and they scanned for viruses, trojans, etc., etc., etc., and there is nothing there, but this email address account keeps coming back on any computer I have installed Thunderbird, including new computers that are new out of the box. The email account I want to remove is clogged with spam and tying up my internet connection and the ISP (Charter Communications) will not help me by eliminating this particular email account. I have followed multiple instructions I have found on this forum about how to remove an unwanted email account from Thunderbird and not a single one works because the selection to do this does not exist in Thunderbird. All I get is asked for a password for the email address that the ISP says doesn't exist, but it is being flooded with hundreds of thousands of emails that get sent to this email address in my Thunderbird program. Every time I run Thunderbird, it locks into this particular account and downloads emails until my hard drive is full and crashes. Is there a way to get rid of this email account on Thunderbird or do I just remove the whole program from my computer and use something else?

There are many answers to the question of how to disable message threading. All are from earlier versions than mine, which is 115.7.0 -- as witnessed: Sorry! 0 results found for ‘disable threading in version 115.7.0’ for ‘Thunderbird'

Thunderbird seems to have so many minor changes and alterations in the recent past, that basic usability is affected. Not a good thing.

Once before, a few years ago, Thunderbird got so out of control that I had to go to a different mail client. Are we back to that?

Emails won't send on Thunderbird. I get this message: "Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtpauth.earthlink.net timed out. Try again." My outgoing server is: Description: EarthLink Server Name: smtpauth.earthlink.net Port: 587 User Name: kenndixi@earthlink.net Authentication method: Normal password Connection Security: STARTTLS

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?

How does one enable calendars in Thunderbird version 115.8.0? When I click the calendar icon on the left of the page, I get a calendar displayed but it has a message highlighted in yellow that says: "All calendars are currently disabled. Enable an existing calendar or add a new one to create or add events."

I cannot find anything in settings or elsewhere to enable calendars.

TIA

Ever since the last "upgrade" which is terrible I get my emails in threads. Does anyone know how to get rid of the stupid threaded messages? I've tried everything. All I want is emails to be listed in the order I received them. I DO NOT WANT THREADS

Every time I try to reply to a my question on this forum I am now seeing the following message after I submit it:

An Error Occurred Oh, no! It looks like an unexpected error occurred. We've already notified the site administrators. Please try again now, or in a few minutes.

I use the latest FireFox on Win10. When looking for a solution the only one I found suggested cleaning out my cache data. I did that but it still fails. This issue started yesterday (or maybe two days ago).

Thoughts?

Recently all cox.net emails transferred to yahoo mail but kept the cox.net address. I prefer the Thunderbird format for emails, more options. How can I add them to Thunderbird? I already have them in Thunderbird with the cox.net address but no new emails are coming in on the ones that have already transferred to yahoo mail. (They didn't all go at the same time so I am still getting emails on the ones that didn't transfer yet.) Thanks.
