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.

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

With the moving of Cox emails to Yahoo would it be feasible for Thunderbird to put an instruction list(with screenshots) of how to get all our TB email accounts from Cox to TB? Do we have to delete all our TB email accounts and re-enter them into TB under the new Yahoo or can we just change the server settings on the existing Cox settings? If just changing server settings what are the settings for the new yahoo? All my accounts are IMAP so if instructions could be made, maybe one for IMAP and one for POP for those who use either. Thank you

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]

Your instructions for unthreading do not work. The commands you suggest do not appear in my "View" folder. And I do not want to unthreads many dozens of folders manually.

Please provide guidance on how to fix this, or I will have to abandon Thunderbird (which I have used loyally for many years) or work via the Gmail platform (ugh).

I can't seem to be able to edit Address Book entries in TB 115.3.3.

I highlight the email to change and can't do anything with it

In fact the address book is no longer found under Tools.

Even though highlighting text is a SUPER minor feature, it is one I would love to see in Thunderbird. I am using Release 115.6.1 (64-bit) and would love to have that capability. I searched for add-ons but the only one I found had been withdrawn by its author. Please advise if that capability exists and how to install it. Thanks, mkcgkc@gmail.com Ken Cawthorne

'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?

The ability to change font size is disabled. I lost my User profile on my PC, and I am starting from scratch with all settings. My custom folders are still there, but I have had to recreate message filter rules, and I can't get the font large enough to read.

Note: When I click on the image I provide below, it makes it look like my font size is huge. It is not.

I have thunderbrird on both my laptop and computer, i got home, and did my normal, and on my computer it come up with Authentication Failed, its only doing it on the computer, but no the laptop, i have version 115.4.1, on both, but howcome it only doing it on the computer not the laptop? should i re-install on the computer?? or is their another way to fix this problem?

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?

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 when I try to get to the window to enter my password: 400. That’s an error. The server cannot process the request because it is malformed. It should not be retried. That’s all we know.

On opening Tbird I have started getting a Google pop up asking me to sign in to Google to continue to Tbird. This is just annoying as I can access all my email accounts without signing in to Google. I just have to close the annoying pop up every time I open Tbird. How can I stop this happening?

I changed my Xfinity password on Xfinity website. Now I get error message on Thunderbird.saying my imap password is wrong. How can I change my imap and outgoing email passwords to match xfinity password.
