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 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:

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 am looking of the name of a address book I added. I know the\at the main book is called abook.sqlite. I have other sqlite files called abook-1.sqlite, abook-2.sqlite and abook-3.sqlite. What are these file contain? Also where are the other info like "Notes" stored? Are they also in the abook.sqlite file. I am using a DB browser and i don't see that info in the file.

I have 4 email accounts with Thunderbird. When a message comes in it is posted on ALL of the accounts. What am I doing wrong? My main email address is: [edited from community support forum] @rogers.com. Kindly answer to this address. I am 83 years old and don't under stand the young way of talking.....please be specific. Thank you very much. Bryan Baker.

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

This is the only place I thought might match my request.

Well, maybe not so much support, but a request.

Any chance of adding a dedicated notes tab?

There are times I need to jot down ideas on an email, or quickly need to have data available readily.

DON'T want to have to open another application JUST to take down info.

Thank you for a great product.

I have been using Thunderbird for ages now with no problem, but I suddenly realised that no recent emails were appearing from my Gmail account. I have tried everything suggested on line to resolve the problem, including uninstalling and reinstalling Thunderbird, and deleting and re-entering my acccount details but neither the IMAP or SMTP servers will connect to Gmail. I have reset all of the server settings on Thunderbird, and have checked that Gmail is IMAP compliant (which, apparently, is is now automatically). I have spent hours trying to sort this out and am just at the point of abandoning Thunderbird completely, but I am loathe to do so if there is a solution. The latest error message i have received is "Unable to log in at server. Probably wrong configuration, username or password" but I don't know what else I can check or change.

On my Linux machine, I exported the public key for an email address in Thunderbird 140.8.0esr (64-bit) into a file. I transferred the file to my Windows 11 machine via Warpinator.

On the Windows machine I am running Thunderbird 148.0.1 (64-bit). In Account settings>End-to-End encryption, I click Add Key>Import an existing OpenPGP key>Select File to import, and then I select the file.

I get an error message: Error! Failed to import file.

I'm surprised. I would think that going from one installation of Thunderbird to another would work this way. I am concerned that I won't be able to read incoming encrypted emails without the key working.

Can someone help me?

About 140.8 ESR. Use the internal spam filter or externals like Bogofilter or SpamAssasain? 2nd: RSS option (Blogs and Feeds) every so often downloads duplicate feeds - how to remove duplicates?? Last: Earlier versions Thunderbird can import Outlook Templates - anyone knows how??? Example: I want to send my mom a Mother's Day email with a nice background but the background does not have to be animated - how would I go about that? I have plenty of email templates from Outlook 95/XP - just not sure how to import and use.

Bei Absenden der email (wilhelm-wisch@t-online.de) folgende Fehlermeldung: "Senden der Nachricht fehlgeschlagen. Fehler beim Senden der Nachricht, SMTP-Server Fehler. Der Mail-Server antwortete: IP=38.246.32.196 - Your address is blocked.

Please help, thank you!
