Thunderbird Support Forum

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?

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.

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, I installed the latest Thunderbird on OS X Monterey for a friend and am using an Imap email account. Sending and receiving emails is working correctly. The problem is viewing what is in the inbox, it shows a certain number in the inbox but not all of those messages are showing up, some are missing. I've played around with the settings but I didn't see anythng that could help me out. On my own computer this works correctly, when I see a number in the inbox, it does show all of those email messages. Not sure what is going on, maybe it's simple like a setting not done correctly, or I missed something. Anyway, any help would be appreciated.

Thanks

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.

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?

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 have had a Thunderbird email program for several years. Recently, when I send an email a copy of it is not saved in the "Sent" folder. My emails are received by reciepents. How do I fix the problem?

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?

Hi Folks. About a year and a half ago I some how got hacked in communication with a help desk somewhere. From that point on , I have not been able to use my Thunderbird email. It asks for my password that I do not have. I have spent hours trying to reset it. I have tried a clean reinstall, but it recognizes me and asks for my password. I have my email addresses saved and would be happy to do a fresh install, but I have not been able to figure out how to do this. I am very much obliged for any help you may offer. Thanks Tom Adams , [edited] @comcast.net [removed email, phone# and location privacy info from public]

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?

When I open Thunderbird all the emails are listed BUT they are double spaced. This is not the spacing of an email response, just the way they are displayed when TB is opened. I'm sure it is a simple mouse click selection but it eludes me. Can anyone suggest the choice? There are two computers and one of them displays exactly they way wanted. The other one show each email double spaced before opening it. The attached image is the display I want. Thanks for any help.

Previous versions of TB did not chain or link replied messages to the original and were received as separate messages. So if I have a reply to a message it comes in in TB as a new received message. Now however it is linked to the original so there are "sub messages" linked under the original. How can I change that TB behavior back to the single message only? Replies get buried under multiple layers of linked messages which is often an issue even seeing a new one come in.

Tnx for anyone who may provide guidance. Searching the TB forums has not provided an answer.

After trying to change the name of a large folder with a lot of important information I cannot access anything and when I do the following message appears:

Unable to open the summary file for Accounts on david.vasmer@gmail.com. Perhaps there was an error on disk, or the full path is too long.

Any idea how to restore my access?

Thank you to anyone who cam help

'Hola, I still have message ID & user agent & X account key in the header of my emails, along with the date. I NEVER had them before; I don't need them. How do I get rid of them?
