Today I have experienced a problem downloading new messages, bulk, trash or anything else in my mail server into thunderbird. it requires my primary password and then my regular password. I just set up my primary password so I understand why it is asking for that, but I don't understand why it is also asking for my regular password before I can get access to the mail server that I am using. the regular password was set up on 6/17/24 and until today it was working fine.

There is a folder in my Downloads folder ('~/Downloads') called 'thunderbird.tmp' Whenever I delete it it reappears whenever I open Thunderbird. How do I relocate this because I like to keep my Downloads folder neat? I have not found an option for this anywhere in settings on the app.

I use apple mail on my phone and Thunderbird on my PC and my (IMAP) email provider is GMX. I recently added a couple of sub-folders to an existing folder and changed the names of couple of others (in the same main folder). I did those changes on my phone. However, those changes are not reflected on my PC. The folders with changed names are in the folder list but greyed out but the new folders are missing. If I click on a greyed out folder it is empty. I've tried several ways to force the list to update but, so far have been unsuccessful.

What is causing my problem and how can I fix it?

Thanks for any advice.

I've been trying to move my Thunderbird data (148.0) from a Win10 to a Win11 machine. I've meticulously followed both the methods outlined at http://mzl.la/1ApHiU3. I have copied my original profiles.ini from the ...AppData\Roaming folder to that location on the new machine, then corrected the drive locations in the file (see attached profiles.ini image). (yes, the correct "j4sqsccb.XXXXXXX" folder is copied to the new installation's root: a bulky several-GB)

In order to try to replicate my original computer's admittedly-awkward installation from long ago, I have added the suffix " -p -no-remote" to the desktop icon's Target field. And on startup, the new T-bird does properly show my original profiles in the Select panel - even though I only ever used the one that functioned correctly, identified as 1 in the profiles.ini file (see Choose User Profile image, IDs X'ed-out).

However, on selecting that profile on the Win11 machine, Thunderbird just takes me to the account setup screen, as if it's unable to locate or load the account settings for that profile.

I'm only doing this clunky method of copying-over out of ignorance; I'd be very happy to simplify the mess I'd created decades ago with my original installation. OR if you think I'm better off wiping all evidence of past installations to start from a clean install, I'll be happy to do that. Please let me know if you need additional info I've failed to provide here!

Also adding images of my ...Roaming\Thunderbird\Profiles folder and Installs.ini file, just in case!

Hi,

I configured my account using the server's IMAP service. Every time I open Thunderbird, it asks me for the password of the calendar service of that IMAP service. But it doesn't have a calendar service. Even if it has, I don't want to use it.

I looked everywhere in the settings page, but could not find a way to disable it.

Why the app keeps asking me for the calendar service's password and how to disable it?

Thanks.

I have problems every time I try to fetch my imap gmail, with Thunderbird complaining that: "The certificate for imap.gmail.com:993 does not come from a trusted source".

As near as I can tell, imap.gmail.com:993 is still the recommended setting for

Version is Thunderbird 148.0.1 (64-bit). Adding an exception for the missing certificate does not seem to make a bit of difference.

I do not know if the use of Bitdefender as my security and vpn software is a factor. I notice that the certificate (exception certificate?) shown when I click on View Certificate in my gmail account settings appears to mention Bitdefender, so perhaps that's a factor. That certificate looks as follows:

Certificate Subject Name Common Name imap.gmail.com Issuer Name Country US Organizational Unit IDS Organization Bitdefender Common Name Untrusted Bitdefender CA Validity Not Before Mon, 02 Feb 2026 08:37:57 GMT Not After Mon, 27 Apr 2026 08:37:56 GMT Subject Alt Names DNS Name imap.gmail.com Public Key Info Algorithm Elliptic Curve Key Size 256 Public Value 04:2D:20:DA:19:33:1D:AC:28:91:52:02:EB:B8:7E:33:C0:B7:E4:F3:5E:4E:88:92:E5:7E:BB:30:0C:6C:E4:84:A8:3D:D7:49:9B:22:C8:C0:BB:01:80:4B:84:30:3A:3B:73:70:8F:AB:EB:C0:F0:D5:7B:8B:0B:64:1B:DC:76:67:41 Miscellaneous Serial Number 1A:50:ED:15:50:A1:A7:93:5D:05:8A:CD:85:A5:15:FD Signature Algorithm ECDSA with SHA-256 Version 3 Download PEM (cert)PEM (chain) Fingerprints SHA-256 12:8A:58:44:DF:B5:E1:E4:EF:CC:F7:35:09:BA:6E:88:86:16:15:78:F9:28:52:23:FC:0E:E9:69:D1:AF:21:86 SHA-1 A3:30:CB:65:39:51:46:9B:3B:BC:0B:B9:09:DD:26:40:A8:52:25:3D

I just updated from TB 142.0 to 148.0.1. After the update, my Yahoo and AOL accounts display a login window and prompted to re-enter the login credentials. After I enter the email address and click 'Next' an error is displayed:

Edge: Too Many Requests

This appears to be a browser error. What is needed to fix this? I am unable to re-enable my email addresses.

When I tried to copy the link to a 'real' browser window I was able to get the verification code from the sites, but then got the error Can't reach this page at 127.0.0.1, connection refused which, of course, is the loopback address.

I have saved relevant e mails to local folders in my Thunderbird account on my Applemac. I opened up Thunderbird on my MacBook and downloaded my Thunderbird account but it did not copy those local folders, merely 1 empty folder. Without these also shown in my Thunderbird account when I am away from home, I cannot see those records. I am struggling to find a solution. Are you able to help please? Alan Dowler

I have been using Thunderbird with two POP3 Hotmail accounts for some time and I am trying to set up a third account with exactly the same configuration. However, both the automatic and the manual configurations failed. The new account receives mail, but the outgoing smtp server config seems to have a problem. Sending messages times out or keeps prompting for a new password.

The Hotmail account has POP3 and IMAP enabled. Thunderbird is set to receive all cookies. I cleared history and cache after every attempt and also temporarily disabled the firewall.

Any suggestions about what the problem could be?

Hi there. I'm looking for a shortcut that takes me from the folderlist pane to the message pane and the first new message, when I'm on the inbox folder. The tab is not good. It moves between to many fields/options.

Thunderbird--All of my current year INBOX emails disappeared. I have tried repairing the folder, deleting INBOX.msf and restarting including in troubleshooting mode, reinstalled Thunderbird. None of these actions changed the situation. Is it possible to retrieve these messages?

The INBOX folder is much larger than the INBOX.msf folder, so I'm thinking the message info is in there?

I;m using Windows 10.

Good morning . . . I have recently switched from an old Windows 10 machine to a new macmini, and have switched my Office 365 account over to it. Simply stated, Outlook is not working, and I have no desire to continue with it. Will Thunderbird suit my needs? Will it allow me to import my old contacts and emails, both from my Windows machine and the new MacOutlook?

A few days ago I started getting a failed sign in for one of my emails. The solution seems to be that my authentication method in ≡ > Account Settings > Server Settings does not give OAuth2 as a choice. Screenshot shows what is available. All other email authentication methods have that as a choice. Is this a problem with the email program or T'bird? T'bird is 140.8.1esr (64-bit) O/S is Win11 Thanks for your help
