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

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.

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?

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.

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.

Need to set up Thunderbird to receive emails from yahoo. Cox is transitioning emails to yahoo presently have two addresses : cliven@cox.net and daciaandclive@cox.net

Is there a built-in way or an addon that will allow the ability to create folders as a filter action?

I can move or copy to an existing folder but is there a way to make a folder in a specific location with a specific name based on previous parameters.

Thanks in advance!

Version 115 is absolutely horrid! I was surprised recently by an apparent automated update and it has thrown off my email routine enough to seriously consider changing clients. The user interface is unusable, folders are disappearing from view, and is aesthetically a mess. As a 10+ year user of Thunderbird, I'm going back to 91 or will find a new product...

Thunderbird will no longer save sent emails to my SENT folder. I get an error message when I send an e-mail saying, "Your message was sent but a copy was not placed in our sent folder(Sent) due to network or file access errors. You can retry or save the message locally to Local Folders/Sent-using my email address. Cox Communications is my ISP and they say the problem is not theirs.

Numerous users of Thunderbird have expressed their total dissatisfaction with the recent upgrade, especially the new font and layout in the email lists. Why has the Mozilla team ignored requests to return to the previous load to restore the font and list displays? Do you expect users to support your product when they totally do not like the new version?

I have installed Thunderbird on a new (Windows 11) lap-top. When I get to "Account setup>>Set up existing email address", and enter my password, I get the response "Configuration found in Mozilla ISP database", but when I click "Done," there is a long hesitation on "Checking Password", and finally the message pops up "Unable to log in at server. Probably wrong configuration, username, or password." I know my username and password are correct. All configurations appear to match those on my old lap-top. Server is att.net.

I prefer Thunderbird for composing, reading, and replying to emails, and have a decade's worth filed and stored locally on an older lap-top, which I will want to import.

After decades of using Thunderbird it has amassed contacts. Even for my own contact it saves a contact like "lynn@szetosolutions". incomplete email addresses, or associated with DMV...just for my own email it has saved 7 versions and or affiliations. I want to clean up and remove the excess, inaccurate email addresses that keep auto filling my emails and reduce the constant annoyance. Can someone help me? I'm so grateful for any help.

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.

I recently reset my desk top and after that my thunderbird will not open without a password that I have not got. I need a simple way to find the password or otherwise allow me to reinstal a new download. I have tried for two days using lots of suggestions from web and help but I cant get past the request for a password
